Do you know how the bubbles on the bubble film are formed? The manufacturer of 3 layers bubble film machine tells you that there has always been such a problem. Let's take a look at how the bubble wrap that many people like to pinch by hand is made.

The 3 layers bubble film machine manufacturer tells you that according to different raw materials, the raw materials are mixed evenly through the soft film mixer, and then sent to the next mixing process according to different raw materials.
The raw material is put into the extruder. The 3 layers bubble film machine manufacturer tells you that at a high temperature of 230°C, the raw material particles are heated and melted, and the resin melted into a paste will be sent to the film forming blow molding machine.
Films are made by extruding and expanding resin. Cylindrical films are made by pulling at the outlet of the film while injecting air. Injecting air can make the thickness of the film more uniform.
Then, the cylindrical film is cut with a knife into two films, which are then received on a roll. The two films are made into a double-layer film through a pressure roll, softened by heating the film, and then slowly wound on a vacuum forming roll with round holes. A thin film is absorbed by the round hole, forming a vacuum bubble.
3 layers bubble film machine manufacturers tell you that these bubble films can be cut and bundled for packaging. I've always thought these bubbles were inflationary. As it turns out, they are simple. In the future, I can pinch the foam safely and boldly.
