During the production process of cross-linked films, high-energy rays are used to act on polymer molecules, making them generate active groups such as free radicals. These active groups then further react with each other, and finally the cross-linking of molecular chains is achieved. All the properties of cross-linked films are stronger than those of ordinary POF shrink films, but they are more expensive.
Regular cross-linked shrink film: In contrast to conventional POF shrink films, this particular film exhibits a superior shrinkage rate and enhanced strength, thereby offering robust protection. Boasting high light transmittance, it serves as an ideal packaging film for product transportation. It effectively ensures product sealing, keeping out impurities and moisture in the air, thus preventing product spoilage.
Anti-fog cross-linked shrink film: This material showcases outstanding anti - fog properties, effectively inhibiting water vapor from condensing on the surface of the film. As a result, the packaging remains crystal - clear, enabling consumers to have an unobstructed view of the products inside. Thanks to these features, it is highly suitable for packaging frozen and refrigerated foods in supermarkets.
Low-temperature cross-linked film: It demonstrates excellent shrinkage capabilities even at relatively low temperatures. When dealing with products that must avoid exposure to high temperatures during the packaging procedure, the low - temperature cross - linked film emerges as an ideal choice. This film is well - suited for packaging applications with stringent low - shrinkage temperature demands, effectively safeguarding products from potential deformation or damage.
