Printing method for composite plastic flexible package

Abstract

The invention relates to a printing method for a composite plastic flexible package. The method involves a bottom plate, a cleaning device, a gluing device and a bonding and winding device. The method can solve the following problems possibly occurring in the plastic film gluing and bonding process of existing equipment that a, when the existing equipment glues plastic film, the plastic film cannot be effectively sucked and fixed generally, so that the plastic film is liable to slip in the gluing process, the gluing effect is poor, and then subsequent processing of the plastic film is influenced; and b, when the existing equipment performs gluing, the phenomenon of non-uniform gluing often occurs, so that the thickness of the glued plastic film is not uniform, the bonding effect is poor, the production quality of the plastic film is reduced, and then the quality of the composite plastic flexible package is influenced.

Description

technical field [0001] The invention relates to the field of composite plastic flexible packaging manufacturing, in particular to a printing method for composite plastic flexible packaging. Background technique [0002] Composite plastic flexible packaging is a new type of plastic packaging made of two or more layers of plastic film through glue coating, pattern printing, hot pressing and other processes. It has the advantages of light weight, softness and strong protection. widely used. At present, the most used on the market is double-layer composite plastic flexible packaging. Before printing the pattern, it is usually necessary to glue the plastic film first. [0003] At present, the existing equipment may encounter the following problems in the process of gluing and bonding the plastic film: a. When the existing equipment is gluing the plastic film, it usually cannot effectively absorb and fix the plastic film, The plastic film is prone to slip during the gluing proc...

Problems solved by technology

[0005] The present invention can solve the following problems that the existing equipment may encounter in the process of gluing and bonding the plastic film: a. When the existing equipment is gluing the plastic film, it usually cannot effectively absorb the plastic film fixed, causing the plastic film to slip easily during the gluing process, resulting in poor gluing effect, which in turn affects the subsequent processing of the plastic film; b. Existing equipment often has uneven gluing when gluing phenomenon, resulting in uneven thickness of the bonded plastic film and poor bonding effect, thereby reducing the production quality of the plastic film, which in turn affects the quality of the composite plastic flexible packaging
