Process for producing antibacterial food packaging bag having anti-counterfeiting function

Abstract

The invention discloses a process for producing an antibacterial food packaging bag having an anti-counterfeiting function. The process comprises the following steps of preparation of an antibacterialfilm: weighing raw material soybean fiber, potassium permanganate powder, nano silica powder, paraffin, polyethylene resin, polyhydroxyalkanoate, gelatin and plasticizer, melting and evenly mixing the paraffin, the polyethylene resin, the polyhydroxyalkanoate and the gelatin, and standing to make a mixed material; evenly mixing the soybean fiber, the potassium permanganate powder, the nano silicapowder and the plasticizer to obtain a mixture; adding the mixture into the mixed material, and performing melt blending to obtain a blended material; performing hot pressing on the blended material;performing cold press molding after hot pressing, and obtaining the antibacterial film. The preparation of the antibacterial packaging bag includes performing printing on a reverse side of the antibacterial film; performing spray printing of an anti-counterfeiting code on the reverse side; and compositing a PE film below the well printed antibacterial film, to form a composite film; curing the composite film; performing spray printing of an anti-counterfeiting image layer on the front of the composite film, and after code spraying, performing slitting to manufacture an independent packaging bag. According to the process, the antibacterial food packaging bag can kill various harmful bacteria and have a bacteriostasis effect and strong anti-counterfeiting performances.

Description

technical field [0001] The invention belongs to the technical field of packaging, and in particular relates to a production process of an antibacterial food packaging bag with an anti-counterfeiting function. Background technique [0002] At present, due to the low production cost and convenient use of packaging bags, they have been more and more applied to various fields of people's lives. Producing packaging bags with antibacterial function has become an urgent problem to be solved. [0003] At the same time, in order to protect their products, manufacturers print various anti-counterfeiting identification codes on the surface of ordinary packaging bags. The anti-counterfeiting identification codes on this product packaging bag or roll film are uniformly formulated. Although there is a certain anti-counterfeiting effect, but This anti-counterfeiting code is not unique, and the anti-counterfeiting property is not strong, which causes inconvenience in product management and...

[0002] At present, due to the low production cost and convenient use of packaging bags, they have been more and more applied to various fields of people's lives. The production of packaging bags with antibacterial function has become an urgent problem to be solved

[0003] At the same time, in order to protect their products, manufacturers print various anti-counterfeiting identification codes on the surface of ordinary packaging bags. The anti-counterfeiting identification codes on this product packaging bag or roll film are uniformly formulated. Although there is a certain anti-counterfeiting effect, but This kind of anti-counterfeiting code is not unique, and the anti-counterfeiting performance is not strong, which causes inconvenience in product management and unsatisfactory anti-counterfeiting effect
