Multi-color overprinted tipping paper with metallic luster and preparation method thereof

Abstract

The invention discloses multi-color overprinted tipping paper with metallic luster and a preparation method thereof, wherein an aluminized tipping base paper layer, an ink layer and a gloss oil layerare arranged sequentially from inside to outside. The tipping paper takes an aluminum layer of the aluminized tipping base paper as a printing face, and a bottom color adopts a transparent alcohol ester ink. Polar hydroxyl groups contained in the ink can be bonded with metal aluminum, and have excellent adhesion force to metal aluminum, so as to realize direct printing on a metal aluminum layer. At the same time, the ink is matched with tackifying resin, so that the bottom color ink layer adheres firmly to the metal aluminum layer and the multi-color overprinted ink layer without stripping. Inaddition, the adopted ink solvent has good release property, and the safety and hygiene indexes of the tipping paper product meet the standards. Under the mutual combination of metallic luster of thealuminum layer and the luster of the ink, the tipping paper has the advantages of obvious metallic luster visual effect, rich color, high-grade luxury, decoration with strong stereo texture and a certain anti-counterfeiting property.

Description

technical field [0001] The present invention relates to ink and tipping paper, more specifically to a multi-color overprint tipping paper with metallic luster and a preparation method thereof. Background technique [0002] Tipping paper is a special industrial paper, which is mainly used for connecting filter tips and cigarettes, commonly known as "tipping paper". With the enrichment of material and spiritual life in modern society, and the change of people's consumption concept and health awareness, there are new requirements for cigarette packaging. The use of tipping paper is not limited to simple packaging, but also pays more attention to decoration. Tipping paper has greater market potential and development space. [0003] The printed matter printed with metallic luster can produce a shiny, translucent, luxurious, elegant, chic, peculiar, and magnificent visual effect, which greatly improves the grade and taste of commodity packaging, and is especially popular in the f...

AI Technical Summary

Problems solved by technology

Ester-soluble ink has strong adhesion, and can obtain a firm ink layer on the aluminum layer. In order to obtain colorful printed products, the subsequent overprinting process must use the same system of ester-soluble ink, but the solvent release of the ester-soluble system is poor, and the product VOC residues in the medium exceed the standard

At present, there is also a method of first coating a layer of primer on the aluminum layer and then printing to overcome the problems of adhesion fastness and solvent residue, such as the disclosed invention patent "transfer-type tipping paper and its preparation method, application number: 201710228740.4", which provides a method of first coating a transparent primer solution containing resin on the metal aluminum layer, and then printing with gravure ink, so as to solve the problem that it cannot be printed directly on the metal aluminum layer, but setting such a primer process, there are defects of increased production cost, low production efficiency and monotonous color
