Problems solved by technology

In the prior art, due to the small peeling force of the decorative film, usually below 100g, during the cold stamping process, the hot stamping images and texts tend to have low definition and coating powder falling off, which affects the quality of the printing process and affects the whole process. The production environment and decorations cause pollution, and it is difficult to clean the equipment

Abstract

The invention discloses a transfer print type decorative film suitable for a cold wave technology. The transfer print type decorative film comprises a base material, a release layer, a metal layer and a bonding layer, wherein the release layer comprises the following components in part by weight: 600 to 2,000 parts of acrylic resin, 100 to 400 parts of rosin resin, 30 to 120 parts of amino resin, 3 to 50 parts of aid and 2,000 to 3,000 parts of solvent. According to the decorative film, stripping force between the release layer and the base material can reach more than 100 grams, powder cannot fall in the cold wave process, and graphics and words are high in definition; and the decorative film can be widely applied to decorative processing of surfaces of plastic films, plastic packaging products and the like in a package printing industry.

Description

technical field [0001] The invention relates to a decorative film, in particular to a transfer-printing decorative film suitable for cold stamping technology. Background technique [0002] In recent years, due to the increasing importance of printing and packaging, unique and beautiful design and processing techniques have gradually become a part of commodity packaging technology. In the fierce market competition, in order to increase the added value of products and carry out more effective packaging anti-counterfeiting and decoration, more and more packaged goods adopt bronzing technology. Hot stamping technology is divided into hot stamping and cold stamping. The early hot stamping technology is mainly hot stamping. Cold stamping technology has developed rapidly in recent years, and can be applied to flexographic printing and lithographic printing. The main application scope of cold perm technology: wine labels, medicine labels, beverage labels, candy paper, wine boxes, c...
