Abstract

The invention discloses perfumed laser-jet paper. The laser-jet paper comprises multiple layers, and comprises a varnish layer, a laser-jet layer, an aluminum-plated layer, a composite adhesive layer, a base paper layer and a back coating layer in sequence from exterior to interior, wherein a perfuming coating is added into one layer or several layers of the varnish layer, the laser-jet layer, the composite adhesive layer and the back coating layer. According to the perfumed laser-jet paper disclosed by the embodiment of the invention, on one hand, the one layer or the several layer in the structure of the laser-jet paper are subjected to perfuming treatment, the perfuming coating is added into the one layer or the several layer in the structure of the laser-jet paper, an attractive faint scent is emitted, and the purchase desire of a consumer is stimulated, and on the other hand, a modified polyvinyl alcohol high molecular polymer is added into the perfuming coating, besides that the modified polyvinyl alcohol high molecular polymer can form intermolecular hydrogen bonds with organic essence molecules containing hydroxyl groups in a natural plant essence, the self cross-linked structure of the modified polyvinyl alcohol high molecular polymer can more effectively restrain the essence molecules, and the effect of slowly releasing a perfume is achieved.

Description

technical field [0001] The invention relates to the technical field of the packaging industry, in particular to a scented laser paper. Background technique [0002] Laser-sprayed aluminum paper, referred to as laser paper, is a high-end packaging paper that loads laser holographic patterns or text signals on the surface of aluminized paper by molding. Laser paper is widely used in cigarettes, food, medicine and other packaging materials due to its gorgeous colors and decorative effects. [0003] Laser paper is divided into direct composite laser paper and transfer laser paper. Direct composite laser paper is made by directly compounding laser film and base paper with composite glue; while transfer laser paper is made by compounding laser film and base paper, and then peeling off the laser film to transfer the aluminized layer to the base paper through adhesive action. Compared with composite laser paper, transfer laser paper is more environmentally friendly and economical,...
