Abstract

The invention discloses an upper and lower film integrated packaging bag. A bag body structure of the packaging bag comprises an upper film, a lower film, a bottom sheet material and a side accordion,wherein the upper film, the lower film and the bottom sheet material are of an integrated structure; and the bottom sheet material is positioned between the upper film and the lower film. The packaging bag has the beneficial effects that the upper film, the lower film and the bottom sheet are of the integrated structure, cutting is not needed, the cutting process is reduced, and film loss is reduced; the upper film and the bottom sheet material as well as the lower film and the bottom sheet material in the integrated structure do not need secondary packaging, so that the strength of the bag body is enhanced, and the service life is prolonged; and technical equipment is simple in structure, convenient to operate and high in applicability.

Description

technical field [0001] The invention relates to the field of packaging bag processing machinery, in particular to a packaging bag with an integrated upper and lower film, as well as equipment and a processing method for processing the packaging bag. Background technique [0002] Packaging bags refer to bags used to pack various supplies, which make the goods convenient to transport and store during the production and circulation process, and are widely used in daily life and industrial production. Traditionally, the upper film, lower film and bottom sheet of the packaging bag are an independent split structure or the lower film and the bottom sheet are integrated and separated from the upper film. Under this structure, the separation between the film and the film passes through The ironing method is fastened, and the firmness and reliability of the ironing place are low, which may easily cause the rupture of the bag body. [0003] Therefore, those skilled in the art are com...
