Abstract

The invention relates to a composite-bag-surface-scratch-prevention bag making method and system. The method comprises the following steps of: (1) covering a layer of non-heat-sealing type protective film on the external surface of a non-heat-sealing type outer membrane of a composite membrane; and (2) synchronously moving the protective film and the composite membrane to be subjected to a bag making process of a bag making machine together, thereby obtaining composite bags. The system based on the method comprises a composite membrane feeding mechanism, a first guide mechanism, a heat sealing mechanism, a traction roller and a discharging device which are sequentially arranged along the advancing direction of the composite membrane; a protective film feeding mechanism is arranged in front of the first guide mechanism; the protective film delivered by the protective film feeding mechanism covers on the external surface of the non-heat-sealing type outer membrane of the composite membrane; and the protective film and the composite membrane synchronously enter the first guide mechanism. During the process of bag making, only the protective film is scratched by a plurality of guide rollers and the traction roller of the bag making machine, and the surface of the composite membrane is not scratched, so that the problem that scratches exist on the surfaces of the composite bags is solved.

Description

technical field [0001] The invention relates to a compound bag making method and a bag making system, in particular to a method and a bag making system for preventing the surface abrasion of the compound bag making bag, and belongs to the technical field of compound bag production. Background technique [0002] Composite bag is a bag made of composite film, which is a kind of packaging bag commonly used in commodity packaging at present. The composite film used to make composite bags is usually composed of two or more single-layer films. Most of the composite films are provided with an outer film that does not have heat-sealing properties and is used to contact the object to be packaged. Sealing inner membrane. When making bags, the composite film is first folded in half, so that the outer film without heat-sealing properties of the composite film faces outward, and the inner film with heat-sealing properties faces inward, and then the folded composite film is heat-sealed a...
