Problems solved by technology

Due to the thickness and compatibility of the polyethylene coating, the PE layer cannot always have good adhesion to the substrate, that is, the paper, and it is easy to peel off during production, causing production interruption, or peeling off in actual use.
In order to solve this problem in industry, it is often used to burn the base paper, or corona to eliminate the surface impurities to improve the adhesion between plastic and paper, but due to the similar compatibility of plastic and paper, it has little effect

Abstract

The invention relates to a coated paper for an instant noodle cup lid and a preparation process thereof, and relates to the technical field of composite paper. The coated paper for an instant noodle cup lid comprises a base paper layer, a first coated layer and a second coated layer from bottom to top, An adhesive layer is provided between the first coating layer and the base paper layer, and the adhesive layer includes the following components in parts by weight: 40-60 parts of polyacrylate, 20-40 parts of epoxy resin, 10 parts of polyisobutylene ~30 parts and 3~5 parts of dibenzoyl peroxide, the adhesive layer also includes a solvent, the solvent includes ethyl acetate and cyclohexane, the amount of ethyl acetate is equal to the total amount of polyacrylate and epoxy resin, and the cyclohexane The amount of hexane is equal to the amount of polyisobutylene; the preparation process includes: S1. Adhesive layer preparation; S2. Second coating layer preparation; S3. Adhesive layer coating; S4. First coating; S5. Second coating ; S6. Post-processing. The invention solves the problem of poor adhesion between the PE layer and the base paper layer by arranging an adhesive layer between the PE layer and the base paper layer.

Description

technical field [0001] The invention relates to the technical field of composite paper, in particular to an instant noodle cup lid coated paper and a preparation process thereof. Background technique [0002] Coated paper is a material that attaches plastic particles to the surface of the paper and is composited with paper. The main feature is that the composite material has good oil-proof, waterproof and heat-sealing properties. Different uses of coated paper have different requirements on its performance: when it is used to pack hamburgers, it has higher requirements for oil resistance; when it is used for coated paper packaging, it has higher requirements for water resistance; When it is packaged in an automatic packaging machine, the requirements for its heat sealing performance are relatively high. [0003] Plastic particles for coated paper are usually made of polyolefin materials, among which polyethylene coated paper is mass-produced in China due to its dimensional ...
