Abstract

Belonging to the technical field of plastic bag processing, the invention discloses a preparation method of an anti-counterfeiting high strength plastic bag. The method includes the steps of: (1) preparation of anti-counterfeiting masterbatch; (2) weighing of raw materials for standby use; (3) mixing treatment; and (4) extrusion molding. The preparation method provided by the invention has a simple overall process and reasonably collocated steps, is easy for mass production and manufacture, and the prepared plastic bag has high mechanical strength, good weather resistance and stable anti-counterfeiting quality.

Description

technical field [0001] The invention belongs to the technical field of plastic bag processing, and in particular relates to a preparation method of an anti-counterfeiting high-strength plastic bag. Background technique [0002] Polyethylene plastic bags are a kind of plastic bags with a very wide range of applications. However, they usually do not have anti-counterfeiting functions. Ink, or sticking anti-counterfeiting labels, etc., not only affects the appearance of the product, but also increases the processing procedure. Moreover, these anti-counterfeiting technologies are widely used anti-counterfeiting technologies, which can be easily seen by counterfeiters, thereby imitating corresponding anti-counterfeiting marks. [0003] Chinese patent CN102815444A discloses a lined anti-counterfeiting soft package, which is packaged with a product and an anti-counterfeiting thread on the flexible packaging bag. The middle section of the line is suspended. The invention eliminat...
