Properties Of PET Shrink Film

PET shrink film is a new type of heat shrinkable packaging material. Because it is easy to recycle, non-toxic, tasteless, good mechanical properties, especially in line with environmental protection, polyester (PET) has become an ideal substitute for polyvinyl chloride (PVC) heat shrinkable film in developed countries.


This is one of the greatest features of shrink film packaging. With the help of the super strong winding force and retractability of the film, the products are compactly and fixedly bundled into a unit, making the scattered small parts a whole, even in an unfavorable environment. edge and stickiness to avoid damage.

primary protection

The primary protection provides the surface protection of the product, forming a very light and protective appearance around the product, so as to achieve the purpose of preventing dust, oil, moisture, water and theft. It is particularly important that the stretch film packaging can make the packaged items evenly stressed and avoid damage to the items caused by uneven force, which cannot be achieved by traditional packaging methods (bundling, packaging, tape, etc.).

compression fixity

The product is wrapped and packaged with the help of the retracting force of the stretched film to form a compact unit that does not take up space, so that the pallets of the product are tightly wrapped together, which can effectively prevent the mutual misalignment of the product during transportation. Moving, while the adjustable stretching force can make hard products close to each other, and soft products can be shrunk, especially in the tobacco industry and textile industry, which has a unique packaging effect.

cost saving

The use of stretch film for product packaging can effectively reduce the cost of use. The use of stretch film is only about 15% of the original box packaging, about 35% of the heat shrinkable film, and about 50% of the carton packaging. At the same time, it can reduce the labor intensity of workers, improve packaging efficiency and packaging grades.
