Problems solved by technology

Water-based resin is added to the water-based transfer coating, that is, the blend system of water-based acrylic acid and cellulose acetate butyrate; the water-based acrylic acid has high gloss under the condition of ensuring various unique properties of the acrylate coating, and removes most of the organic volatile solvents. Substitute for water, so as to achieve the purpose of greatly reducing air pollution, and completely solve the problem of bad smell and light reflection caused by solvent-based coatings; while cellulose acetate butyrate has good storage stability, UV resistance, cold resistance, flexibility, Transparent, electrical insulation and other properties

Abstract

The invention relates to a seamless PET (polyester) laser transfer membrane which comprises a carrier PET base membrane, a protection layer, an imaging layer and an aluminum layer, wherein the protection layer is a transfer coating layer, a transfer coating is prepared by adopting raw materials by weight percent: 12-40 percent of water-based resin system, 6-10 percent of ionic copolymerization monomer, 3-7 percent of a diluent, 40-68 percent of dispersion medium, 1-5 percent of a pH modifier and 4-8 percent of a crosslinking agent. The invention also relates to a preparation method of the seamless PET laser transfer membrane. The seamless PET laser transfer membrane provided by the invention is strong in metal luster and excellent in mechanical property, moisture prevention and weather resistance. The surface of the seamless PET laser transfer membrane adapts to various printing processes, and thus various artistic designs can be printed.

Description

technical field [0001] The invention relates to a seamless PET laser transfer film and a preparation method thereof, belonging to the field of new polymer materials. Background technique [0002] Since the laser packaging material was put into the market, its application in the fields of food, medicine, daily chemical products, tobacco and wine has been rapidly promoted, and its organic combination with color printing technology has become the most cutting-edge technology product in the world's printing and packaging industry. With the development of the world's green environmental protection requirements, the environment-friendly laser transfer film mainly using BOPP and PET as the carrier base film gradually replaces the traditional aluminum foil or plastic composite materials. But in contrast, the overall performance of BOPP transfer film is not as excellent as that of PET transfer film, and the recycling rate is not as high as the latter. Therefore, PET transfer film has...
