What is stretch film and what is its use

Stretch film, also known as stretch film and heat shrinkable film, was the first in China to use PVC as the base material, DOA as the plasticizer and self-adhesive effect to produce PVC stretch film. Due to environmental problems, high cost (large relative PE ratio, less unit packaging area), poor stretchability and other reasons, when the domestic production of PE stretch film began in 1994 to 1995, it was gradually eliminated. PE stretch film was firstly made of EVA as self-adhesive material, but its cost is high and tasted. Later, PIB and VLDPE were used as self-adhesive materials. The base material is now mainly LLDPE, including C4, C6, C8 and metallocene PE. (MPE).


The production process of the stretch film promotes itself to have good self-adhesion, good tensile properties, strong penetration resistance, tear resistance, high transparency and high retraction rate. state.





It is used for the packaging of single items such as food, chemical raw materials, light textile products, fertilizers, and mechanical and electrical products, as well as pallet packaging and other bundled packaging.


In addition, it has the properties of high strength and puncture resistance, and wrapping the articles can make the packed articles stable and tidy, and also has the function of waterproof. are widely used in various aspects.
 

It is mainly used for packaging products and strengthening them. Many enterprises can use them in machinery factories, food factories, can factories that make tinplate, food canning factories, glass bottle factories, wineries, and many many stretch films are characterized by shrinkage and energy. It can strengthen and protect many easy-to-touch and fragile things, because most of these products cannot be used with ropes or packing belts.
