Abstract: The invention relates to an inflatable composite film and a manufacturing method thereof, which are composed of an upper film, a lower film, an upper valve film, and a lower valve film, etc.; firstly, they are coated between upper and lower air valve films. The cloth has a heat-resistant coating solution, and then the upper and lower air valve films are sandwiched between an upper film and a lower film to form a multi-layer film group, and then the multi-layer film group is formed by a copper mold It is molded once by hot embossing and finally wound on a rolling bar to form a roll of inflatable composite film. The inflatable composite film is provided with a straight heat-seal line, upper and lower transverse heat-seal lines, an inlet heat-seal line, an oblique heat-seal line, a reticulated hot-printing point, a folding line and the like, so that each air chamber is independent , And in a roll type continuously wound on the scroll bar. The present invention can elastically cut different lengths to increase the application range of the packaging bag body and has a more beautiful overall appearance.
Sovereignty items: 1. An inflatable composite film comprising: an upper film, a lower film, an upper valve film, and a lower valve film, characterized in that the inflatable composite film is provided with straight heat Sealing lines, upper and lower transverse heat-seal lines, inlet heat-seal lines, diagonal heat-seal lines, mesh-like hot-printing dots, folding lines, etc., make each air chamber independent, and continuously wind in a roll type On the scroll bar.
