Problems solved by technology

[0003] However, it usually does not have an anti-counterfeiting function. When it is used in some fields that require anti-counterfeiting, it is necessary to additionally set special anti-counterfeiting marks on the polypropylene film, such as printing anti-counterfeiting ink, or pasting anti-counterfeiting labels, etc., which affects the appearance of the product. additional processing steps
And because these anti-counterfeiting technologies are widely used anti-counterfeiting technologies, it is easy for counterfeiters to see, thereby imitating the corresponding anti-counterfeiting marks

[0046] Examples 1-40 and Comparative Examples 1-6: Preparation of polypropylene anti-counterfeiting film

[0047] A kind of preparation method of polypropylene anti-counterfeiting film, its raw material formula is as shown in table 6~10, and its preparation method comprises the following steps:

[0048] Weigh each component by weight, and use two large and small extruders to extrude polypropylene, processing aids and the anti-counterfeiting masterbatches prepared in Tables 1 to 5 to the co-extrusion head, polypropylene and processing After the additives are mixed evenly, they are extruded from the large extruder, and the anti-counterfeit masterbatch is extruded from the small extruder. After extruding the two-color foam tube, it is blown, drawn, and wound to obtain a polypropylene anti-counterfeiting film with anti-counterfeiting strips. ; Wherein, the barrel temperature of the two large and small extruders is equally divided into three sections for control, followed by feedin...

Abstract

The invention discloses a polypropylene anti-counterfeiting film and a preparation method thereof. The polypropylene anti-counterfeiting film includes, by weight, 100 parts of polypropylene, 0.1-20 parts of anti-counterfeiting masterbatch and 0-1 part of a processing aid. The anti-counterfeiting masterbatch includes, by weight, 30-99.9% of a carrier resin, 0.01-15% of a fluorescent powder, 0.01-65% of a coding material and 0-3.25% of an auxiliary; and the carrier resin is polypropylene. The preparation method is as below: conducting extrusion molding on polypropylene, processing aid and anti-counterfeiting masterbatch to a coextrusion head by using a large extruder and a small extruder respectively; evenly mixing polypropylene and the processing aid and extruding from the large extruder; extruding the anti-counterfeiting masterbatch from the small extruder; and extruding a double color bubble tube, and conducting blowing, traction and rolling. By adopting specific coextrusion film blowing process, the anti-counterfeiting strip and the polypropylene film are combined into one body to gain good binding force; the production process is simple, low in anti-counterfeiting cost, and easy for processing and moulding and mass production; and according to the fluorescent features and coding information on the anti-counterfeiting strip, authenticity and traceability of the product can be realized.

Description

technical field [0001] The invention relates to the technical field of packaging anti-counterfeiting, in particular to a polypropylene anti-counterfeiting film and a preparation method thereof. Background technique [0002] Polypropylene film has many excellent properties, such as low relative density and high mechanical strength. In particular, it has a high degree of transparency and heat resistance, making it widely used, especially suitable for small packages of clothing, food and various daily necessities. [0003] However, it usually does not have an anti-counterfeiting function. When it is used in some fields that require anti-counterfeiting, it is necessary to additionally set special anti-counterfeiting marks on the polypropylene film, such as printing anti-counterfeiting ink, or pasting anti-counterfeiting labels, etc., which affects the appearance of the product. The processing procedure has been increased. And because these anti-counterfeiting technologies are ...
