Description

technical field

[0001] The invention relates to the technical field of shrink films, in particular to an anti-rust and anti-fog PE shrink film and a processing method thereof. Background technique

[0002] The coating film of the product outer packaging plays an important role in the storage, quality assurance and beautification of the product itself. At present, the coating film used in the domestic packaging market is more commonly used as PE shrink film. This product has the advantages of good flexibility, strong impact resistance, strong tear resistance, not easy to break, and large shrinkage rate.

[0003] The traditional PE shrink film used in the packaging market is a film blown by a single-layer blown film machine. Due to its small shrinkage rate and shrinkage force, various functions are not complete. For example, the invention patent application of CN1285663C discloses a high-transparency polyethylene heat-shrinkable film, which consists of 4-6 parts by weight of ...
