Polyethylene membrane laser holography false proof method

Abstract

The invention relates to polyethylene film laser holographic anti-fake method, which can effectively solve the anti-fake problem of the polyethylene film packages. The method is characterized in that the polyethylene is made into package film coils by blow molding and flow casting; through corona treatment, the brand patterns are made on polyester film or poly-propyl film coils by the laser holographic anti-fake technology; after that, low-temperature transfer mediums are coated on the polyester film or poly-propyl film coils, and the existing anti-fake pattern coils are compounded on the surface of the polyethylene film; through the treatment of heat preservation, the two coils are peeled and coiled by a peeling device; the anti-fake patterns are firmly attached to the surface of the polyethylene film and does not deform; the films with the holographic anti-fake patterns are printed into motley packages by a printing machine, and colorful luster and printing patterns of the holographic anti-fake motley coexist on the polyethylene films. The invention has the advantages of not affecting the name of the product, patterns and hot sealing, laser holographic anti-fake effect when applied to the bag preparation, leading a user to ensure the property right not to be infringed.

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:
