Production method of high environmental protection water-based transfer cardboard

Abstract

The invention discloses a high-environmental friendliness aqueous transfer paperboard production method. The method comprises treating a PET polyester film through a gravure roller of a coating machine so that water-based paint with solid content of 15% bonded in ink cells of the gravure roller is instantaneously bonded to the surface of the PET polyester film and an aqueous transfer resin layer is formed and carrying out drying through an oven of the coating machine so that 85% of water is transformed into water mist from liquid and is discharged into air. The discharged water vapor in air does not cause pollution. The method can realize high-level environmental protection of a domestic eco-friendly paper and drives the whole industry eco-friendly development. The product can greatly satisfy high and low temperature resistance of the PET on the market, is nontoxic and odorless, has good safety and good environmental friendliness, keeps the original luxuriant appearance of the paper, can be directly used for food package, cigarette label package and wine package and can provide great convenience for life of people.

Description

technical field [0001] The invention belongs to the field of cardboard production, and in particular relates to a production method of high-environmental protection water-based transfer cardboard. Background technique [0002] Transfer cardboard is a new type of cardboard newly developed in recent years. It is mainly used for printing high-end packaging such as cigarette packs, wine packs, and cosmetics; traditional transfer cardboard transfer coatings are basically solvent-based, and solvent-based coatings contain 75- 85% of solvents, these solvents volatilize into the air in a large amount during the production and printing process, which is easy to cause environmental pollution; in addition, the traditional transfer cardboard has poor surface gloss and is only suitable for low-end packaging, which cannot meet the needs of people today. The need for luster and aesthetics. Contents of the invention [0003] Aiming at the problems existing in related technologies, the pur...
