Problems solved by technology

Because these processes need to go through several high temperatures, even if BOPP and PVC films can be made into metallized holographic laser anti-counterfeiting films, due to high temperature pre-shrinkage, their shrinkage properties have completely disappeared, and cannot be applied to packaging that requires heat shrinkage

Embodiment Construction

[0017] 1. Metallized holographic laser anti-counterfeiting shrink film

[0018] The metallized holographic laser laser anti-counterfeiting shrink film has a BOPP shrink film layer 1 with a thickness of 20 μ ~ 100 μ, and a polyurethane curable adhesive layer 2 is compounded on the shrink film layer 1, and a 300 The aluminum-coated layer 3 of ~380 Å is compounded with a holographic laser anti-counterfeit molded layer 4 on the aluminum-coated layer 3, and the side of the molded layer 4 that meets the aluminum-coated layer 3 has anti-counterfeit patterns and / or characters molded by a molding machine, The molded layer 4 is compounded with an acrylic resin transparent release paint layer 5 (this layer faces outwards when used for packaging).

[0019] 2. The cold transfer production method of the metallized holographic laser anti-counterfeiting shrink film

[0020] The method is to adopt a thin film substrate layer, and sequentially coat a transparent release coating layer 5 and a h...

Abstract

The metallized holographic laser anti-fake shrinkage film includes one shrinkage film layer, adhesive layer, aluminum plating layer, molded holographic laser anti-fake layer and transparent demolding paint layer. It is produced through cold transferring process, in which one transparent demolding paint layer and one holographic laser paint layer are coated successively onto one film substrate, the holographic laser paint layer is molded to form the molded holographic laser anti-fake layer, on the molded holographic laser anti-fake layer, one vacuum aluminum plating layer is plated, one adhesive layer is painted and one shrinkage layer is stuck, and the film substrate is finally peeled off. The shrinkage film of the present invention is suitable for packing commodity.

Description

technical field [0001] The invention relates to a heat-shrinkable composite film for packaging with anti-counterfeiting performance and a production method thereof. Background technique [0002] At present, the outer shrink film used for packaging goods generally adopts BOPP, PVC transparent shrink film or printed shrink film, which cannot be further processed. In particular, its thermal shrinkage performance affects its development in the direction of high-grade deep processing such as metallization and holographic laser anti-counterfeiting. As we all know, my country's holographic laser anti-counterfeiting materials have developed rapidly, and generally use PET film as the base material, and are made by hard pressing or soft pressing. Since these processes need to go through several high temperatures, even if BOPP and PVC films can be made into metallized holographic laser anti-counterfeiting films, due to high temperature pre-shrinkage, their shrink...
