There are many types of film blowing machines, including PE, POF, PVC, etc. The new materials blown out with new particles are new materials with uniform color, clean, and good bag stretching. The film blowing machine needs to use high-temperature blowing technology to blow film during the production process, which will generate higher temperatures. In this process, this type of cooling mechanism plays a very important role.

[0003] The existing film blowing machines are generally large in size, and the film blowing area at the upper end thereof will generate high temperature.
