What are the general properties of heat shrinkable films

Primary Protection:

Primary protection provides surface protection of the product, creating a very light protective appearance around the product, heat shrink film thus protecting against dust, oil, moisture, water, and theft. The outermost shrink wrap is especially important in order to subjecte the packaged item to a uniform force and avoid damage to the item due to uneven force, which cannot be achieved by traditional packaging methods (binding, packaging, tape, etc.).

Compression Fixity:

With the help of the retraction force of the stretched film, the product is wound and packed into a compact unit, which does not take up space, so that the product pallet is tightly wrapped together,heat shrink film effectively preventing the products from being misaligned and moving with each other during transportation. At the same time, the adjustable tension can bring hard products closer to each other and make soft products tighter, especially in the tobacco industry and textile industry, with a unique packaging effect.

Cost Savings:

The use of film rolling machine for product packaging can effectively reduce the cost of use. The amount of winding film used is only 15% of the original packaging box, 35% of the heat shrink film, and 50% of the carton packaging. At the same time, it can reduce the labor intensity of workers and improve packaging efficiency and packaging grade.
