Problems solved by technology

The vacuum aluminized paper made by this process method has the following disadvantages: because the nitrocellulose coating on the surface of the aluminized paper becomes rough when the polyester film is peeled off, the surface finish of the aluminized paper is poor and lacks luster; The process makes it difficult to control the color difference of the product; due to the poor ability of nitrocellulose to resist organic solvents, the surface printing adaptability of the aluminum-coated paper made is poor, and large-area printing cannot be carried out

Abstract

The invention discloses a preparation method for an aluminum-plated paper packaging material for cigarettes. The preparation method comprises the following steps: (1) coating a polyester thin film with stripping coating, wherein the stripping coating layer consists of the components in percentage by weight: 18-22 percent of cellulose acetate resin, 7-9 percent of bi-chloride-vinyl resin, 24-26 percent of acrylic resin, 1.5-2.5 percent of polypropylene wax, 1-2 percent of dioctyl phthalate, 0.5-1.5 percent of a titanate coupling agent, 0.2-0.4 percent of 2-hydroxy-4-methoxybenzophenone, 0.1-0.2 percent of dibutyltin dilaurate and the balance of butanone; (2) performing vacuum aluminum plating; (3) adhering composite paper; (4) performing stripping to obtain the aluminum-plated paper packaging material for the cigarettes.

Description

technical field [0001] The invention relates to the technical field of packaging materials, in particular to a method for preparing an aluminized paper packaging material for cigarettes. Background technique [0002] Vacuum aluminized paper is a packaging material used in the packaging industry in recent years. It has a good metallic texture and is suitable for processing on embossing machines and high-speed cross-cutting machines. It has the advantages of avoiding light, moisture, and degradability. It can replace Aluminized plastic films and pure aluminum thin composite materials have broad prospects due to their low aluminum consumption, and have been widely used in the packaging and decoration of cigarettes, food, medicine, and trademarks. At present, the vacuum aluminized paper with coloring effect all adopts the pre-coloring method. The process method is to coat a polyester film with an easy-peelable coating made of nitrocellulose, and then coat it on the easy-peelable...
