UV-energy-curing cold-ironing-technology alumite thermoprinting film

Abstract

The invention discloses a UV-energy-curing cold-ironing-technology alumite thermoprinting film. The UV-energy-curing cold-ironing-technology alumite thermoprinting film comprises a base layer, a peeling layer, a color layer, an electroplated layer and a glue layer, wherein the base layer, the peeling layer, the color layer, the electroplated layer and the glue layer are sequentially connected; theglue layer comprises UV glue; the UV glue is prepared from, by weight, 65-80 parts of polyurethane acrylic resin, 15-30 parts of vinyl resin, 10-30 parts of pure solid acrylic resin, 5-10 parts of adhesion promoter, 25-45 parts of solvent, 5-10 parts of initiating agent and 1-5 parts of assistant. According to the alumite thermoprinting film, when the UV glue is cured, a easy-to-peel alumite foilfilm after being peeled is not required to conduct synchronous delivering, the corresponding film use length of a peeling-easy alumite foil film corresponding to a part which is not required to be coldly ironed in the film feeding direction can be wound or stop to be delivered through a foil film rewinding device at this moment, the next step is not required to continue to be carried out, possible waste of the peeling-easy alumite foil film in the next step can be effectively avoided, and thus the production cost is greatly reduced.

Description

technical field [0001] The invention relates to the technical field of anodized aluminum hot stamping film, in particular to an anodized aluminum hot stamping film with cold stamping technology cured by UV energy. Background technique [0002] Hot stamping film refers to the technology of combining laser holographic anodized aluminum film with hot stamping technology to form colorful laser holographic marks and anti-counterfeiting marks of three-dimensional patterns on the surface of printed matter. This technology can add laser encryption and anti-tampering layer on the back, which is used for anti-counterfeiting of documents, cards, bills, trademarks, etc. If this kind of anti-counterfeiting mark is added on the outer packaging of the product, its anti-counterfeiting strength is unmatched by the current single laser holographic anti-counterfeiting mark. In addition, special laser holographic anodized aluminum films can be made for products according to the requirements of...

Problems solved by technology

However, the problem is that the mass production rate of the cold stamping printing machine is low due to the limitation of process materials, and the cold stamping technology is complicated and unstable, resulting in high loss costs.
