Problems solved by technology

[0003] The existing laser-coated aluminum-coated paperboard preparation process generally includes direct composite laser paper, transfer composite laser paper, and transfer composite laser paper is one of our more commonly used processes, but the existing process is in the process of transfer composite laser paper. The temperature resistance of the laser coating used is poor, which affects the actual product application

Abstract

The invention discloses a high-strength heat-resistant laser packaging material and its processing technology; the invention adopts a film transfer method to place a PET film or a laser PET film on glue-coated horse paper or cardboard for compounding, and then peels off the PET film, aluminum Molecular layers are transferred to paper or cardboard through gluing to prepare laser anti-counterfeiting vacuum aluminized paper with radiant arbitrary patterns and arbitrary characters. This paper can be used as packaging materials for cigarettes and food, and is widely used in the packaging field; The invention coats laser paint on the surface of the base film to form a laser coating. The base film can be selected as any one of PET film, PVC film, and BOPP film; the overall process design is reasonable, the operation is simple, and the prepared laser packaging material has Excellent temperature resistance, and the peeling effect of the entire packaging material is good, green and environmentally friendly, and the prepared vacuum aluminized paper can be widely used in the packaging field.

Description

technical field [0001] The invention relates to the technical field of packaging materials, in particular to a high-strength heat-resistant laser packaging material and its processing technology. Background technique [0002] With the increasingly fierce market competitiveness, our product packaging materials are also increasing to meet the ever-changing packaging styles. Commodity packaging is the image of the commodity and the mark that distinguishes it from other commodities in the same industry, which stimulates consumers' desire to buy and facilitates consumers to make differentiated purchases; in the prior art, the anti-counterfeiting printing and packaging industry mainly consists of bronzing paper, laser film, laser plating Aluminum cardboard and other packaging materials. [0003] The existing laser-coated aluminum-coated paperboard preparation process generally includes direct composite laser paper, transfer composite laser paper, and transfer composite laser pape...
