How is the stretch film manufactured and what are its properties?

Stretch film is a popular name for polyethylene film. It is a packaging material made of linear low-density polyethylene (LDPE for short). The most important properties of stretch film are its high flexibility, transparency, thermoplasticity and stickiness. The production processes of polyethylene film are quite complex. How is stretch film made?How to make stretch film?
The manufacturing industry mainly uses two methods of creating stretch films, which differ from each other not only in the technology used, but also in the devices. What are these methods?The Blow method is translated from English as blowing. It consists in melting synthetic resin, which is then blown in two directions: machine and transverse. The next stage is air cooling of the material. This method is much more time-consuming, but it was created using it.The stretch film is much more resistant to punctures and has better bonding conditions. It is mainly used in agriculture and food industry.The machine casting method is also called cast in English. In this case, the raw material is directly poured out of the corresponding head, and then quickly stretched and cooled using specialized extruders. This is a method that is characterized by high production efficiency, but the equipment needed to implement it is extremely expensive. The stretch film created in this way is characterized by high elasticity and better tear resistance. It is mainly used in transportation and storage for packing pallets and cargo.What properties does stretch foil have?
One of the most important features of stretch film is that it is directly related to the material it is made of. LDPE is lightweight, flexible and heat shrinkable. Moreover, the method that was chosen to create it also has a great impact on the properties of a particular product. Blowing allows you to create films with a wide range of thickness, stretch, and damage resistance. However, in the case of machine casting, the final product is characterized by much greater extensibility and flexibility.An important property of polyethylene film is its impermeability to odors, which is why it is often used in the catering industry to protect products and semi-finished products used indoors.
