[0002] Bubble film is made of high-pressure polyethylene as the main raw material, and then added with whitening agent, opening agent and other auxiliary materials. It is extruded and blister-formed into bubbles at a high temperature of about 230 degrees. It is a new type of plastic packaging material with light texture, good transparency, non-toxic and odorless. It can prevent moisture, cushion and keep warm for products. It is also called bubble pad.

[0003] At present, when producing bubble films, it is necessary to perform heat pressing treatment on the bubble films. During the heat pressing treatment, for example, a heat pressing device for producing bubble films is proposed in patent publication number CN117621417B. In this patent, a collecting roller is driven to rotate by a second rotating rod, so that the produced bubble films are rolled up. In the rolling process, the following problems may occur: 1.
