Description

Technical Field

[0001] The utility model relates to the technical field of cooling devices, in particular to a plastic film cooling device. Background Art

[0002] Plastic film is a thin, soft and tough sheet material made of plastic; different types of plastic film have different characteristics, but in general, plastic film has the following advantages: Lightweight and soft: Plastic film is light, soft, easy to process and carry. Excellent barrier properties: It can effectively block the penetration of moisture, oxygen, carbon dioxide and other substances to protect product quality. Good weather resistance and corrosion resistance: Plastic film has excellent weather resistance and corrosion resistance, and can maintain stable performance in various environments.

[0003] In the processing of existing plastic films, the plastic particles are first heated and melted, extruded through an extruder, blown into plastic film through a blower, and then heat-sealed and cut through a bag-making machine to finally make a plastic bag.
