Abstract

The invention discloses an anti-ultraviolet thermal shrinkage film. The thermal shrinkage film comprises a thermal shrinkage film body, adhesive layers and anti-ultraviolet coating layers, the thermalshrinkage film body is vertically provided with an upper surface and a lower surface, the adhesive layers adhere to the sides, away from the thermal shrinkage film body, of the upper surface and thelower surface correspondingly, the anti-ultraviolet coating layers adhere to the sides, far away from the upper surface and the lower surface, of the adhesive layers, the upper surface and the lower surface are consistent in thickness, and the thickness of each of the upper surface and the lower surface is 1-2 microns. The thermal shrinkage film has good ductility and flexibility, it is guaranteedthat packaged products cannot be irradiated by ultraviolet rays, and therefore the quality of the product is guaranteed, meanwhile, the preparation cost is low, a production process is simple, and popularization and use are facilitated.

Description

technical field [0001] The invention relates to a heat-shrinkable film, in particular to an ultraviolet-resistant heat-shrinkable film. Background technique [0002] In the field of packaging technology, heat-shrinkable film is essential for product packaging. Heat-shrinkable film has good dust-proof, moisture-proof, and easy-to-observe characteristics. Heat-shrinkable film is mainly used for food, disinfection tableware, medicine, and plastic products. On the packaging; after the product is packaged, the product needs to be packaged and transported. During the process of transportation and product sales, the product may be exposed to ultraviolet radiation, especially some drugs. Radiation regret affects the drug properties, and in severe cases, it will endanger the life, safety and health of patients. The existing heat shrinkable film does not have the characteristics of UV protection, so we propose an anti-ultraviolet heat shrinkable film. Contents of the invention [0...
