Polyethylene membrane laser holography false-proof method

Abstract

The invention relates to a polyethylene film laser holographic anti-counterfeiting method, which can effectively solve the anti-counterfeiting problem of polyethylene film packaging. The pattern is made on the polyester film or polypropylene film coil with laser holographic anti-counterfeiting technology, and then the low-temperature transfer medium is scraped on the polyester film or polypropylene film coil, and the existing anti-counterfeit pattern coil is compounded on the surface of the polyethylene film; After heat preservation treatment, the two kinds of coils are peeled off and rolled by the stripping equipment, and the anti-counterfeiting pattern is firmly attached to the surface of the polyethylene film without deformation; the film with the holographic anti-counterfeiting pattern is printed into colorful packaging by a printing machine, making the holographic anti-counterfeiting The colorful luster and printing pattern coexist on the polyethylene film. The invention does not affect the product name, pattern, heat sealing, and bag making, and also has the effect of laser holographic anti-counterfeiting, so that users can ensure that their property rights are not violated.

Description

1. Technical field [0001] The invention relates to anti-counterfeiting technology, in particular to a laser holographic anti-counterfeiting method for polyethylene film. 2. Background technology [0002] With the rapid development of my country's economy, especially the packaging industry, as one of the carriers of material and cultural exchanges, it has played a role in promoting. All kinds of product packaging are changing with each passing day, which not only protects the product, establishes the product image, but also highlights the brand effect. Especially with the emergence of counterfeit goods in recent years. While the packaging protects the product itself, it also pays more attention to the anti-counterfeiting effect. At present, international and domestic anti-counterfeiting technologies are mainly laser holographic anti-counterfeiting. And it can only be used on paper packaging and high temperature resistant polyester (PET) or polypropylene (BOPP) film packagi...

Problems solved by technology

[0004] In view of the above situation, the purpose of the present invention is to provide a polyethylene film laser holographic anti-counterfeiting method, which can effectively solve the anti-counterfeiting problem of polyethylene film packaging. Under the premise of affecting its wetting tension, the laser holographic anti-counterfeiting pattern is transferred to the polyethylene film surface through the polyethylene film transfer medium (transfer glue), so that the polyethylene film has a specified laser holographic anti-counterfeiting pattern and has a holographic pattern. The thin film is not deformed, the pattern is firmly attached and does not fall off, and becomes the packaging product specified by the customer through printing, and has an anti-counterfeiting effect. Accordingly, the method of the present invention is realized by the following steps:
