What does the back seal of packaging machine mean? Is it related to the installation of triangular bags?

by admin

the back sealing of automatic packaging machine is that there is a sealing line on the back of the bag. This heat sealing line forms an “I” shape with the bag mouth sealing line and bag bottom sealing line, so this kind of packaging effect is also called I-shaped packaging effect. It is a little similar to the triangle bag, that is, the middle sealing line has the same structure and the same molding device. However, triangular packaging is to complete the bag mouth seal and bag bottom seal with a pneumatic structure that turns dozens of degrees respectively. When a package is erected and viewed from above, the two sealing lines form an X-shape.
