Double layer casting does not have three layers of latency in the data

Technical anti-static stretching film use: anti-static stretch film is widely used in all kinds of electronic industries, the anti-static stretch film anti-static index of packaging can reach 10, which belongs to the excellent standard in the industry.

Also equipped with high quality tackifiers, after heating, squeezing, casting, and then cooled by a radification roller, high toughness, high elasticity, tear, high tack, thickness, cold resistance, heat resistance, Pressure, dust, waterproof, single-sided adhesive and double-sided sticking, etc. This is because the casting line produces a uniform thickness and high-level strength, which can be applied to high-magnification pre-stretching.

If you want to know more about the related content of Packaging Tape Manufacturer the stretch film, welcome to the PE stretch film manufacturer, we will serve you wholeheartedly. The surface has tiny, you can stick yourself. Logistics packaging stretch film to the packaged goods to prevent tidal, dust, ban, anti-loss. Early LLDPE stretch film was much blown film, from single layer to the second layer, three floors; today, based on the casting method, LLDPE stretch film is mainly.

The above is the role of the PE stretch film manufacturer to package the stretch film for transportation, hoping to help everyone. The logistics package stretch film is typically added to the PE membrane, such as a PIB masterbatch, after the casting is processed.

Single, double layer casting does not have three layers of latency in the data, and the formula is also high, so it is also reasonable in three-layer co-extrusion layout. Black stretch film is suitable for valuable items, which can effectively anti-theft. Widely used in carton trays, long building materials, food containement, glass ceramics, fertilizer cement, resin raw materials, cloth, empty tank solid cans. 

The supplied melt is converted to a thick and uniform membrane billet

Therefore, the purpose of extrusion theory and process is how to ensure the quality of plasticization Infancy increases on the basis. Any screw must complete the feeding, transport, compression, melting, mixing, and six major functions of exhaust. With the increase in people's living standards, the demand for colorful packaging tape suppliers winding films is greatly increased, then everyone is not very well understood by how the winding film is produced, then how is the winding film produced?

Next, from the PE wrap film The manufacturer briefly introduces the production process of winding film blowing. Feeding and delivery affect the yield of the extruder, compression, melting, mixing, and exhaust directly affect the extrusion quality of the winding film, the quality referred to herein refers to whether or not the melting is complete, but also the compression of the article, whether or not the mix is ​​uniform And the wrapping film products cannot have bubbles, which is the quality of the winding film we are talking about.

Talking about the production process of winding film blowing we have a good requirement for the yield and quality of the winding film, then there must be a good Extrusion system, each of the extrusion systems is associated with each other rather than isolated, the extruder is the key to obtain high-yield and high quality, and the melt is filtered by the mount to ensure the net, the head puts the extruder

The supplied melt is converted to a thick and uniform membrane billet, and the wind ring has a film blister blow molding and controlling the form of a membrane form, and the film soil-free refrigeration device is used to increase the membrane cooling efficiency and discharge membrane. 

So what factors determine the thickness of the stretch film?

In general, the thickness of the stretch film can be determined by market versatile and standardization, and intensity support is generally determined according to the weight of the packaged product, and the thickness of the functional stretch film is generally determined by the shelf life of the product.

So what factors determine the thickness of the stretch film? Next, the PE stretch film manufacturer is briefly introduced. Inhibition of microorganism growth reproduction, the key is to calculate the oxygen coefficient of the stretch film and the permeable carbon dioxide coefficient. May be that the thickness of the strip film material is uneven, and the thickness is too large.

The above is the reason why the winding film has a wrinkle, I hope to help everyone.It may also be tension settings and improper control, and each part of the tension is not coordinated, and it does not match. Why do you have a wrinkle after the finished product . It may be because the position of the substrate of the wrapping film material is deflected, and the degree of wrinkles will increase accordingly as the cumulative of the skew. Why do you have wrinkles after the finished film finished? What is the cause of wrinkles in the winding film?

Next, the PE winding film manufacturer is simply introduced. 3, if the substrate is a film material that scotch packaging tape Manufacturer is susceptible to humidity, and a moisture absorption is happened, and wrinkles are easily generated during extrusion compound.

So, why is the film that will be favored by the user? 1. Next, the PE stretch film manufacturer simply introduces the role of the stretch film and choosing its advantages. The thinness of the stretch film is better, and has a high cost performance, the appearance presents a relatively transparent state, and many films are capable of sticking on both sides. 

The internal and external pressure difference occurs

The other is to pay attention to the accumulation of resources, actively promote or promote the product. . In recent years, the development of most PE stretch film manufacturers is especially true in the market, and the trend of development is still relatively stable.

So why do manufacturers will develop so stable? In fact, in this regard, it is more than one, one is to implement a strict systemist, and strictly control the manufacturers. Anhydrous soaking method, in this way is also commonly used, which is completely charged into the liquid, placed on the filter paper after the seal, if there is an outward leak, then there is a problem of. In the water city pressure method, this kind of vacuum sampling is similar, through vacuum extraction, so that the internal and external pressure difference immersed in water, the inner gas exterior can be initially judged to determine its sealing performance.

By pumping the vacuum, the internal and external pressure difference occurs, and if its product is swollen or the recovery of the shape of the sample after the vacuum, the sealing performance of the sample is determined. With the freedom of their own independent fields, they play their own advantages in their own independent fields, and they compete in each other in the market. Compared with other peers, China Hand Use Stretch Film Manufacturers there are fewer manufacturers to collapse almost in recent years. In addition, there is another important thing to detect quality, this is a level that must pass.

If you have other related questions, please call our PE stretch film manufacturers. So, how can you manage to develop so stable? Next, you will make a simple introduction. manufacturers are very paying attention to quality issues, so that in recent years, the quality testing of stretch film is managed and secret IDE management. Even bankruptcy. Vacuum survey method, this is the method of detection that manufacturers is generally used. Stretch film manufacturers have opened strict testing of stretch film! 

The tensile membrane is obtained by the polypropylene particles after the coextrusion sheet

For manufacturers in some packaging industries, when choosing packaging materials, often in order to simplify the outsourcing and funding of items, give the product a very fancy profile and some simple appearance maintenance.

Many people don't understand the PE color stretch film, which is mainly used for sales and transportation of various products, and its main role is to stabilize, cover and protect products. . One of the materials. With the continuous change in technology age and continuous advancement, the current stretch film is a packaging material that is both convenient and environmentally friendly in the logistics industry. 

The product has strong toughness, high elasticity, anti-tear, high viscosity, is widely used in Plastic clear packaging tape Manufacturer papermaking, logistics, chemical, plastic raw materials. The development of the current market is still relatively good, and its main liquidity is also relatively strong. In summary, Xiaobian is a preliminary understanding of the product.

The tensile membrane is obtained by the polypropylene particles after the coextrusion sheet, and the stretching of the two directions is made, and the main transparency in it increases with the molecular weight. But it is precisely because, we often ignore the true purpose of dust, oil, moisture, waterproof, and preventive damage packaging when we choose. However, there are also some bad manufacturers to make a cost savings for the production of products. The stretch film is nothing more than these reasons.

The final use of the scissors to cut the tray mechanism package

How to distinguish between winding films and stretch film? In summary, it is a method of using a wrapping film and a stretch film, and it is desirable to increase the knowledge of the wrapping film and the stretch film. So our single, double-layer casting does not have three layers of latency in the data selection, and the formula interest is also high, so it is still ideal in three-layer coextrusion.

What we need to know is that the single-layer casting cannot be unique, and the application field is limited. This is because the casting line has the advantage of uniform thickness and high transparency, which is largely applicable to high-magnification pre-stretch requirements. Developed from single-layer to the second layer and three; now producing LLDPE stretch film based on casting method, early stretch film occupying the mainstream position by blown film.

The PE anti-static stretch film packaging must be stretched, and the tray mechanical packaging has direct stretching wrap film Suppliers and pre-stretching. The method is less tensile (about 15%, if the tensile multiplication exceeds 55% to 60%, the original yield point of the film is exceeded, the film width is reduced, the puncture performance is lost, and the film is easily broken). Widely used in foreign trade exports, food, drinks, films, papermaking, dyes, plastic chemicals, glass ceramics, electromechanical castings, etc.

The final use of the scissors to cut the tray mechanism package on the packaging card into a draw form. Abstract Analysis of PE anti-static stretch film characteristics The PE anti-static stretch film is a plastic film having viscous stretchable and wrapped wrap, which is self-adhesive not adhered to the subject, which is only the surface of the apparatus and film.
