Analysis of the role of PVC shrink film

The role of PVC shrink film is transparent, moisture-proof, dust-proof, damage-proof, maintenance and beautification.

Raw materials are easy to shrink, shrinkage environment temperature requirements are not high. They can start to shrink at 40℃, but their strength is greatly affected by the external temperature, and their softness is poor in the low temperature environment. PVC shrink film can be widely used in the outer packaging or collection packaging of doors, windows, profiles, stainless steel tubes, electrical appliances, books, handicrafts and other products.

PVC shrink film is a good film packaging material with the following advantages:

(1) Good anti-theft and dust proof performance;

(2) Heat shrink film packaging bags can pack a variety of commodities to prevent individual small commodities from being lost and make it convenient for customers to carry;

(3) Good transparency so that customers can directly see the packaged goods, convenient for customers to choose goods;

(4) Close to the shape of commodities, PVC shrink film suitable for all shapes of commodities packaging, packaging content is extensive;

(5) By choosing different resins and formulations, heat shrinkable films with different mechanical strength and functions can be prepared. It can be used not only for the inner packaging of low-strength and small commodity weight, but also for the transportation packaging (outer packaging) of mechanical products and the construction materials of containers with high-strength requirements.
