Technical Field

The utility model relates to the technical field of plastic films, in particular to a plastic film with a tensile effect.

Background

Plastic films are films made of polyvinyl chloride, polyethylene, polypropylene, polystyrene and other resins and used for packaging and as a film coating, and plastic packaging products occupy larger and larger portions in the market, in particular to composite plastic flexible packages, which are widely applied to the fields of food, medicine, chemical industry and the like, wherein the plastic films have the largest proportion of food packaging, such as beverage packaging, quick-frozen food packaging, steamed food packaging, snack food packaging and the like, and the products bring great convenience to life of people.

The patent with the bulletin number of CN216782949U discloses a plastic film with tensile effect, including receiving the reel, the surface winding of receiving the reel has the plastic film body, the both sides of plastic film body all are provided with the tensile layer, one side that the plastic film body was kept away from to the tensile layer is provided with high temperature resistant layer.
