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.

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.
