What is the difference between white paper pulp and sugar cane pulp in paper tray products?   Paper tray products are made of many types of materials, such as bamboo pulp, wood pulp, corrugated pulp, large white pulp (also known as white pulp or A4 pulp), sugar cane pulp, etc. Among the many materials used in paper tray products, the most commonly used materials are There are white paper pulp and sugarcane pulp. How to distinguish between the two?   Dry pressed white pulp paper holder In fact, it is very simple. First of all, from the color point of view, although they are all white, the sugar cane pulp paper holder will appear a little yellower, while the white paper pulp is as bright and white as the A4 copy paper we usually use for office use. Secondly, look at the toughness of the product. In general, white paper pulp is rarely used in wet pressing processes. Therefore, in terms of dry pressing products, sugarcane pulp has softer fibers. In addition, the dry pressing product itself is not particularly compact, which makes the dry pressing process difficult. The hardness of paper tray products made from sugarcane pulp will not be as good as that from white paper pulp. Generally, the products selected for dry pressing process are considered from the perspective of product protection. Therefore, it is recommended that you choose white pulp paper tray when making dry pressing paper tray. HUATAO provide more than 80 pulp molding equipment specifications.

Can bagasse be made into paper tray packaging? Advantages of bagasse pulping Sugarcane bagasse is a by-product of sugar mills and a typical raw material for paper fiber. Sugarcane is a stem-like plant fiber stem-like plant fiber raw material. The average fiber length is 1.47-3.04mm, and the bagasse fiber length is 1.0-2.34mm, similar to broadleaf fiber. Sugarcane bagasse is a good raw material for papermaking. Bagasse is a grass fiber. It is easy to cook and blanch. It consumes fewer chemicals and contains less silicon than wood, but less than other grass fiber raw materials. Therefore, bagasse pulp and alkali recovery technology and equipment are more mature and simpler than other straw fiber raw materials. Therefore, bagasse is a cheaper raw material for slurry. Businesses need to tap into renewable resources quickly. Bagasse utilizes low energy-related emissions, helping to reduce global warming. It requires less energy to make because it's just fiber left over from sugar processing. What's more, it's durable and not affected by temperature, making it a useful material in consumer spaces. Notable advantages of bagasse include: Microwave and oven safe Hot liquid can handle 120℃ Oven safe up to 220 degrees Celsius. Bagasse market Research shows that the molded pulp packaging market may exceed US$4.3 billion by 2026. It’s time to look into a truly sustainable resource for manufacturing mold pulp products, namely sugar cane waste. Since sugar cane is a rapidly growing staple food, we have access to more sustainable alternatives. Smarter choice Using agricultural waste is a better option. This waste by-product is already being produced, rather than being cultivated like wood, which takes many years to grow. Bagasse requires much less investment than paper to produce the same amount of pulp. This is an overlooked opportunity when looking for truly sustainable packaging. About 80 cane sugar-producing countries have the potential to better utilize the fibrous residue known as bagasse. Design advantages of bagasse Practical benefits include space savings. Nesting and stacking can reduce storage costs by 70%. Protection is another benefit bagasse provides for outstanding shock and vibration cushioning. Additionally, bagasse can be designed to your specifications, and custom design options are a big advantage. It provides price stability with minimal dependence on oil, gas and resin price fluctuations and gives you long-term price guarantees. It also costs less than other protective packaging options like foam and thermoformed plastic. Products made from sugarcane bagasse do not require a PLA liner and can be used in both home and industrial composting because it is naturally oil- and leak-proof. Bagasse is a great compost material, so its second life as packaging is great for the environment. Sustainable development in the future Bagasse doesn't need any misleading labels, biodegradable labels. It can be home compost or industrial compost. What happens with [sensitive word] is that these products will end up in your home compost, but they may end up being recycled (since they look the most like paper products), being incinerated, and ending up in a landfill. It is important to note if industrial-component materials are placed in landfills. Home composting is something you can do. Composting reduces the production of methane (a major source of greenhouse gases) and provides a range of economic and environmental co-benefits.

What issues should we pay attention to when purchasing a blow molding machine?Huatao Group will take you through all the issues of purchasing a blow molding machine. Huatao Group divides the considerations for choosing a blow molding machine into three parts: blow molding machine quality, case conditions, and after-sales service. Before choosing a blow molding machine, we must first understand the configuration of different blow molding machine products when selecting equipment. , performance, parameters, etc., so you must first understand your own production needs and purchase a blow molding machine in a targeted manner.1. Quality of blow molding machine The quality issue of the blow molding machine is one of the important reference values. As the blow molding machine industry gradually becomes known in China, more and more companies are recognizing the role of blow molding machines and engaging in the production and manufacturing of related industries. Whether the blow molding machine equipment is worn and whether there are safety hazards is related to whether there will be serious safety hazards when the equipment is put into use, whether the production is smooth, and whether the products produced are defective.  2. Case situation Cases are the main means of demonstrating blow molding machine production technology. There is technology but no actual cases, which cannot prove that the blow molding machine can maintain stable operation during long-term operation.3. After-sales serviceBlow molding machine equipment is a large-scale industrial production equipment, and its after-sales service is crucial. Improved after-sales service and timely feedback of equipment problems to the manufacturer for repair can reduce equipment damage. The more perfect the after-sales service, the more protection it will provide to our users, which will be beneficial to future production development.

Why does the bottle mouth expand and outgas occur when the hollow blow molding machine stretches the plastic bottle? How to deal with it? (1) Causes When stretching hollow blow molded plastic bottles, the main reason for the expansion and outgassing of the thread area of the bottle mouth is that the temperature of the space around the blowing device is too high, which reduces the cooling effect of the oven, resulting in the mandrel, The temperature of the threaded area increases. During inflation, the material at the bottle mouth is also inflated due to the high temperature, causing the bottle mouth to become thinner or even cracked, causing outgassing. The problem will be more serious when the temperature is higher, and the sound of air leakage can be heard when the bottle mouth expands.  (2)Processing methods ①Adjust the position of the cooling plate so that it can better protect the threaded area of the preform. The structure of the preform may make it difficult to adjust. ② External cooling can be used to control the temperature of the threaded area and core rod when the preform passes through the oven. ③Improve the structural design of the cooling plate and improve the cooling effect.

A brief discussion on buffer packaging of paper products   With the development of the economy and the improvement of people's living standards, my country's production, circulation and consumption patterns are undergoing tremendous changes, which will bring about the development of the logistics industry. Reducing logistics costs has become a third-party profit source for enterprises. As a result, the requirements for my country's logistics technology are getting higher and higher, which promotes its increasing modernization. The vigorous development of logistics has brought many problems. Paper product packaging occupies an important position in my country's packaging industry. The paper product packaging industry accounts for about 38%, accounting for 1/3 of the entire packaging industry. It mainly analyzes the logistics and transportation packaging supplies in my country. From the current situation and difficulties faced by paper product packaging, as well as some existing problems, to the bottlenecks that restrict the rapid development of my country's logistics in transportation and packaging, we analyze and discuss how to develop logistics towards specialization and modernization.   Paper structural buffer packaging materials mainly include: corrugated cardboard, honeycomb cardboard, pulp molded products, etc. Due to their different structural characteristics and molding methods, these materials are also used differently in buffer packaging applications. The reason why paper structural buffer packaging materials have good buffering properties is not only due to the certain elasticity of their own fiber materials, but also the presence of porous structures or concave-convex structures in the structures of these materials that are suitable for the packaged products. Therefore, Studying the structure of paper-structured cushioning packaging materials is crucial to studying their cushioning properties.

  How to solve the problem of black bars in injection molded products?   Reasons for black bars in injection molded products 1. Thermal decomposition of materials 2. Damage to the screw of the injection molding machine 3. Carbonization of materials due to friction and compression of air   Related knowledge 1. The most common black streaks produced by the residue of material decomposition remaining in the barrel of the injection molding machine. 2. In the plunger injection molding machine, residues tend to remain in various parts. 3. Injection molding machines with valve-controlled nozzles are prone to residue residues in the valve-controlled part. 4. The air in the barrel is compressed to a high temperature. This high-temperature gas combined with the shear heat at the gate can easily form black bars.   Solution 1. Immediately: When replacing materials, reduce the injection pressure and reduce the temperature of the heating barrel. 2. Short term: cleaning of heating barrel (use copper wire brush). 3. Long term: barrel repair.   Due to differences in materials 1. The pigments, paints, lubricants, ultraviolet absorbers, antistatic agents, etc. in the mixed resin are overheated in the barrel. Thermal decomposition of these materials when retained for a long time is also the cause of black streaks. Especially when certain types of additives have poor heat resistance, this tendency will become more obvious. 2. When molding with polycarbonate (PC), it is easy to produce black streaks with a valve-controlled nozzle. 3. Screws with backflow prevention washers are also prone to burnt residue.   HUATAO provides blow molding equipment. Including:  Plastic Mold Equipment Automatic Blow Molding Machine Semi-automatic Blow Molding Machine PS Foaming Machine EPE Foaming Machine PU Foaming Molded Machine Horizontal lnjection Molding Machine vertical lnjection Molding Machine All-electric Injection Molding Machine Thick Sheet Blister Machine Thin Sheet Blister Machine Color Plastic Masterbatch Plastic Recycle Machine     Whether you need help with equipment selection, process optimization, or design customization, our team can help.

Why does the incision position always shift when the toy blow molding machine is stretching and blowing? Why is the bottom of the product not full during stretch blow molding? How to deal with it? The main reasons why the bottom of the product is not full during the stretch blow molding process are: ①The blow molding pressure is not high enough and the blowing air is insufficient. ②The parison temperature during blowing is too low. ③The parison inflation speed is too slow. Why does the incision position always shift when the toy blow molding machine is stretched and hollow blow molded? Solution: ① Check whether the high-pressure filter on the side of the mold is unobstructed to prevent it from affecting the supply of high-pressure air. ② Check the air flow control component of the blower to ensure the correct setting value and that the inside is smooth and free of obstructions.③ Ensure that the air blowing can be completed in the shortest time, otherwise it will bring additional cooling to the material during bottle blowing. ④ Make sure that all ventilation holes (exhaust holes) on the mold are not blocked.⑤ Increase the blowing pressure appropriately.

What are the requirements for extrusion equipment for multi-layer co-extrusion composite hollow blow molding products of float blow molding machine? Multi-layer extrusion blow molding uses several single-screw extruders to provide different polymer melts. The task of the extrusion system is to provide well-plasticized melt to the parison head stably and evenly at the same time. Moreover, this method requires higher uniformity of materials for the functional layer and adhesive layer. Therefore, the requirements for the extrusion device are correspondingly higher. In order to ensure that the extrusion device for multi-layer extrusion blow molding has stable plasticizing performance, the following requirements should generally be met. ①Advanced structure screw and barrel. Proper design of the extrusion system (screw and barrel) can significantly improve extrusion stability. Screw design should fully consider the characteristics of various plastics under operating conditions. The screw length-to-diameter ratio is a major parameter that affects extrusion stability, and it is best to be above 25. In order to achieve good mixing effects, new screw structures (such as separation type, pin type, and corrugated screws, etc.) can also be used to ensure that various additives can be well dispersed and mixed, thereby improving the uniformity of the melt temperature. A slotted bushing should be installed in the barrel feed section to improve extrusion stability and ensure product quality. ② Set up a gear pump between the extruder and the machine head to improve the stability of the extrusion. That is, the melt extruded by the extruder will be pumped into the machine head after being pressurized by the gear pump. The gear pump is a forced displacement device that can discharge a fixed volume of melt per revolution, regardless of the properties of the extruded plastic. In this state, adjusting the screw speed can change the melting and mixing properties of the plastic to facilitate control of the thickness ratio of each layer. ③Use a metering feeding device to control the feeding amount of the extruder to improve the extrusion stability. Since the screw groove is not completely filled, ④The extrusion device used to process multi-layer recycled materials should consider the composition of the recycled materials and their heating history during processing. It is required that the screw can fully mix various resins at the lowest possible temperature rise, especially for resins containing heat-sensitive resins. The material layer, such as PVDC barrier layer, and the screw structure of the extrusion device must be properly selected to ensure good mixing performance at a lower temperature.

Egg paper tray technology and classification   The production process of egg trays is as follows: 1. First make and process the egg tray mold. According to the requirements or sample standards, first make the egg tray blister mold. Under normal conditions, gypsum is used to make the blister packaging mold, but wood carving and metal carving products are also used as molds. After the plaster mold is made, let it dry completely naturally or dry it, and then use a 1-2 mm drill to drill many small holes in the low recesses that will not affect the appearance of the product packaging according to the specific convex and concave conditions of the product surface. For products such as boxes, some small holes must be drilled around the edges so that the air can be extracted during blister production. After drilling the holes in the mold, the plaster mold must be hardened. The hardening method is to use concentrated Soak in alum saturated solution and dry.   2. After the egg tray mold is completely processed and dried, install the egg tray mold on the upper iron plate of the vacuum chamber, then load the plastic sheet into a suitable standard size according to the size of the egg tray mold, and then place the sheet into a heated wooden cabinet. inside, fix it thoroughly, and then place the wooden cabinet and the plastic sheet on a constant temperature furnace for softening. Paper tray packaging   3. Place the softened plastic sheet together with the wooden cabinet in the vacuum chamber, turn on the suction switch, and suck the air in the vacuum chamber clean. After the plastic sheet cools, you will get a concave egg tray that is the same as the mold.   4. Clean up the egg tray. After the produced egg trays are trimmed and cleaned, the finished egg trays are then packaged in cartons and shipped.   Egg trays generally refer to packaging materials used to hold eggs, duck eggs and other eggs. Their main function is to absorb shock and facilitate transportation and carrying. According to different manufacturing materials, they can be divided into paper pulp egg trays, plastic egg trays, etc. According to the number of eggs held, they can be divided into single egg trays and plated egg trays.   Paper pulp egg trays are mostly made of recycled paper pulp and processed by molding machines. Because of its simple manufacturing process, low cost and no environmental pollution, it is called "green" packaging and is the most common type of egg tray in our daily life.   Plastic egg trays use plastic as the material, but they can produce colorful and exquisitely shaped egg trays. Because of its higher cost, it is generally used more in supermarkets.   Single egg trays are generally used at home or in Western restaurants. They are cute in shape and easy to use, and can effectively prevent eggs from rolling off the table. It is an alternative small tableware for fashionable home.   The plated egg tray can hold dozens of eggs in one plate depending on the size, and it is also the most commonly used egg packaging tool.

  How to install the manifold and filter on the plastic blow molding machine?   Placement of manifolds and filters Manifolds come in various forms. Currently, the flat-plate manifolds that are simple in structure and easy to manufacture are commonly used. In order to make the flow rate of materials through the splitter plate uniform, the distribution of holes is often sparse in the middle and dense at the edges. The sizes of the holes are usually equal, and their diameters are generally 2~7mm and increase with the increase of the screw diameter. The layout is mostly arranged in concentric circles, and some are arranged in hexagonal shapes. The total area of the holes is about 30% to 70% of the effective area of the manifold. The thickness of the manifold is determined by the size of the extruder and the amount of pressure it can withstand. , generally 20%~30% of the barrel inner diameter. In order to facilitate the flow of materials and the cleaning of the manifold, the tunnel should be smooth and without dead corners, and a bevel should be provided at the feed end of the tunnel. The manifold plate is mostly made of stainless steel. When placing the manifold plate, the distance from the manifold plate to the screw head should not be too large, otherwise it is easy to accumulate materials and cause heat-sensitive plastics to decompose. However, it should not be too small, otherwise the material flow will be unstable and the quality of the product will be affected. unfavorable. Usually, the volume between the screw head and the diverter plate is less than or equal to the volume of one screw groove in the homogenization section, and the distance is about 0.1D (D is the diameter of the screw). Filters are usually used in situations where product quality is high or high plasticizing pressure is required, such as transparent hollow products, hollow products with high apparent quality requirements, etc., and for extruding UPVC and other materials with high viscosity and poor thermal stability. Generally, no filter or even a manifold is used. The fineness and number of layers of the filter mesh depend on the properties of the material, the form of the extruder, the shape and requirements of the product, etc. The fineness of the mesh is 20 to 120 mesh, and the number of layers is 1 to 5. If a multi-layer filter is used, the fine one can be placed in the middle and the coarse ones on both sides. If there are only two layers, the thick one should be placed against the manifold, so that the fine one can be supported to prevent it from being broken by the material flow. In order to ensure To ensure the quality of the product, the filter should be replaced regularly.

Huatao Group takes you to understand the advantages of disposable biodegradable tableware made of pulp molded tableware Since disposable tableware was first used in my country in 1984, foamed plastic tableware made of polystyrene (EPS) as the main raw material has rapidly spread to every corner of our country, entering people's daily lives and forming a huge consumer market. According to statistics, my country consumes about 10 billion fast food utensils every year, most of which are disposable foam plastic tableware, and is growing at a rate of 25% every year. Due to the shortcomings of polystyrene, such as being non-decomposable and difficult to recycle, it has brought great inconvenience to the external processing work. After several years of hard work, my country's pulp molding disposable catering county production process, technology and equipment have been improved. With rapid development, in terms of varieties, various types of tableware (such as fast food, dishes, plates, bowls of various sizes) required for cold and hot catering have been developed; various food plates, Vegetables, fruit trays, etc. In terms of performance, it can fully meet the requirements of Chinese eating habits and can hold hot soup, oil and water without leakage. Since then, the pulp molding industry has rapidly grown and expanded across China with its environmentally friendly vitality. By the late 1990s, it began to move towards large-scale and industrialization. Currently, eco-friendly containers from nature are molded from paper pulp! 1.

Working principle of PET bottle blowing machine How does the bottle blowing machine work?   The bottle blowing process is a two-way stretching (longitudinal and transverse) process. During this process, the PET chains extend, orient and arrange in two directions, thereby increasing the mechanical properties of the bottle wall and improving the tensile, tensile and impact resistance. strength and good air tightness. Although stretching helps to increase strength, it cannot be over-stretched. The stretch-blow ratio must be controlled: the radial direction should not exceed 3.5~4.2, and the axial direction should not exceed 2.8~3.1. The wall thickness of the preform should not exceed 4.5mm. .   Blowing is performed between the glass transition temperature and the crystallization temperature, which is generally controlled between 90 and 120 degrees. In this range, PET behaves in a highly elastic state and becomes a transparent bottle after rapid blow molding and cooling. In the one-step method, this temperature is determined by the length of cooling time during the injection molding process (such as Aoki bottle blowing machine), so the relationship between the injection and blowing stations must be well connected.   The blow molding process includes: stretching - one blow - two blows. The three actions take a very short time, but they must be coordinated well, especially the first two steps determine the overall distribution of the material and the quality of the bottle blowing. Therefore, it is necessary to adjust: stretching starting timing, stretching speed, pre-blowing starting and ending timing, pre-blowing pressure, pre-blowing air flow, etc. If possible, it is best to control the overall temperature distribution of the preform. The temperature gradient between the inner and outer walls of the billet.

The importance of blow molding machine screw speed control   During the screw speed extrusion process of the plastic blow molding machine, the screw speed is high and the extrusion rate is fast, which can increase the output of the extruder and reduce the sagging of the parison. However, it is easy to cause the surface quality of the product to decrease, and it will also be affected by the shear rate. The increase will cause melt rupture of PE plastics and degradation of plastics with poor thermal stability such as PVC. Usually in the extrusion blow molding process, the screw speed should be controlled as fast as possible on the premise that it can extrude a smooth and uniform parison without overloading the extrusion transmission system. , but generally controlled below 70r/min. In order to control the screw speed below 70r/min, generally the hollow blow molding machine should choose a larger extrusion device.            Blow rate: The volume rate of air introduced during blow molding should be as large as possible to shorten the inflation time and make the product more uniform in thickness and better in surface quality; the air speed should not be too large, otherwise it may form at the air inlet. Low pressure will cause this part of the parison to sink in, or may break the parison at the die opening, making it impossible to inflate.            Blow pressure: The air used for blow molding should have sufficient pressure. Otherwise, it will be difficult to inflate the molded parts or the pattern on the surface of the product will not be clear. Generally, the pressure can be lower for thick-walled products, while thin-walled products and materials with high melt viscosity need to be used. Higher pressure, the general blow molding pressure is 0.2~1.OMPa.             The blow-up ratio refers to the ratio of the maximum diameter of the container to the maximum diameter of the parison, which is the multiple of the parison blow-up. The size of the parison and the blow-up ratio directly affect the size of the container. When the size and quality of the parison are constant, the greater the inflation ratio of the parison, the larger the size of the container. The inflation ratio of the parison is large and the thickness of the container wall becomes thinner. Although raw materials can be saved, inflation becomes difficult and the strength and stiffness of the container are reduced. If the blowing ratio is too small, the consumption of raw materials will increase, the wall thickness of the product will decrease, the effective volume will decrease, the cooling time of the product will be extended, and the cost will increase. Molding should generally be determined based on the variety and characteristics of the plastic, the shape and size of the product, and the size of the parison. Generally, the inflation of large thin-walled products is relatively small, taking 1.2 to 1:5 times; the inflation of small thick-walled products is relatively large, taking 2 to 4 times.
