Description

Technical Field

[0001] The utility model relates to the technical field of cling film processing, in particular to a cling film extrusion molding device. Background Art

[0002] Cling film is a plastic packaging product, usually made through polymerization reaction with ethylene as the masterbatch. Cling film can be divided into three categories: the first is polyethylene, referred to as PE; the second is polyvinyl chloride, referred to as PVC; the third is polyvinylidene chloride, referred to as PVDC.

[0003] In the processing of cling film, an extruder is needed to melt the cling film raw materials and extrude them to the appropriate position. During the extrusion process of the cling film raw materials, the raw materials are prone to adhesion, which can easily lead to the inability to achieve quantitative proportioning of the raw materials, thereby affecting the quality of the cling film after extrusion. In addition, in most commonly used cling film extrusion molding devices, it is not convenient to quickly install and disassemble the extrusion plate. When extruding cling films of different sizes, the through holes on the extrusion plate cannot be changed, and the extrusion plate needs to be replaced, which is time-consuming and labor-intensive.

[0004] Therefore, we propose a plastic wrap extrusion molding device. Utility Model Content
