Embodiment Construction

[0014] The technical solution of the present invention is further illustrated below through specific examples.

[0015] The production method of high-gloss glass transfer cardboard, it comprises the steps:

[0016] (1) Through the compound machine, the paper is transported to the back coating seat through the film unwinding seat, and the back coating glue with a solid content of 8% in the gravure roll is instantly reversed to the back of the paper; to add water to the back of the paper The role of sealing paper fiber holes; the back coating material is a modified acrylic emulsion, which adheres to the back of the cardboard and forms a back glue layer. It has the function of adding water and sealing the base paper fibers, so that the finished paper can reach Moisture balance, in high and low temperature humidity environment, it can keep the paper from increasing and releasing moisture.

[0017] (2) Transport the PET polyester white film from the film unwinding seat to the glue...

Abstract

The invention discloses a production method of a highlight glass transfer paperboard. The method comprises 1, conveying a paper to a back-coating base through a membrane unrolling base through a compounding machine and instantaneously bonding back coating glue to the back surface of the paper, 2, coating the front surface of a PET polyester blank membrane with highlight high-environmental friendliness resin glue with solid content of 20%, 3, bonding the PET polyester blank membrane with the highlight high-environmental friendliness resin glue and the paper, 4, putting the fully bonded paper on a paper unrolling base of a stripping machine and separating the paper and the PET-based membrane of the PET polyester blank membrane with the highlight high-environmental friendliness resin glue and 5, conveying the separated paper with the highlight high-environmental friendliness resin glue layer into a rolling base and carrying out paper rolling to obtain a paper finished product. The back surface of the paper is coated with the highlight high-environmental friendliness resin glue so that a coating process, an aluminizing process and a membrane finished product slitting process are avoided in membrane preparation and thus a cost is saved for the whole industry. The highlight glass transfer paperboard has high environmental friendliness.

Description

technical field [0001] The invention belongs to the field of cardboard production, and in particular relates to a production method of high-gloss glass transfer cardboard. Background technique [0002] Transfer cardboard is a new type of cardboard newly developed in recent years. It is mainly used for printing cigarette packs, wine packs, cosmetics and other high-end packaging. The transfer cardboard currently used includes adhesive layer, paper layer, glue layer, aluminum layer, Solvent-based transfer resin layer and varnish layer have many papermaking processes, heavy workload, high production cost, poor safety performance, and poor surface gloss. They can only be suitable for low-end packaging, and cannot meet people's current needs for gloss and aesthetics. In addition, the current transfer coating for glass cardboard is basically solvent-based. Solvent-based coatings contain 60-80% solvents, and these solvents volatilize into the air in large quantities during the prod...
