Problems solved by technology

[0003] The technical problem to be solved by the present invention is that the existing paper cups have poor barrier performance when the cup body is bonded, and the waterproof, gas-proof and moisture-proof effects are poor, resulting in damage to the cup body, and the quality of the paper cup cannot be guaranteed, which affects the subsequent process. The effect is poor, which increases the production cost, thereby providing a cup body for paper cups

Abstract

The invention relates to a cup body for a paper cup. The cup body for the paper cup comprises paper which is rolled over to form the cup body, a first PE layer, a second PE layer and a printing layer. One bonding end of the paper is provided with a folding portion which is folded inwards, the other bonding end of the paper is provided with a connecting portion of which the inner side is coated with the third PE layer, and the folding portion is provided with a fourth PE layer, a paper layer, a bonding layer, a paper layer and a fifth PE layer in sequence from inside to outside. The cup body for the paper cup has the advantages that the two bonding ends of the paper are provided with the fifth PE layer and the paper respectively, the structure of bonding of the fifth PE layer and the paper is adopted in bonding of the paper, the weakness of bonding of an original PE layer and an original printing layer is improved, barrier property of the bonding position is improved, waterproof performance, airproof performance and damp-proof performance are good, the quality of the cup body is improved, service life is long, stability is good, the damage of the cup body is reduced, and yield of the cup body is improved.

Description

technical field [0001] The invention relates to a cup body for a paper cup. Background technique [0002] At present, paper cups are a kind of paper container made by mechanically processing and bonding base paper made of chemical wood pulp. The appearance is cup-shaped. Paper cups play an important role in people's lives and improve the quality of paper cups. , the cup body used for traditional paper cups is PE layer, paper, PE layer, and printing layer from inside to outside, and then it is wound and bonded into a cup body, so that the PE layer and the printing layer are bonded when bonding, so that The bonded cup body has poor barrier performance, poor waterproof, gas-proof and moisture-proof effects, resulting in damage to the cup body. The quality of the paper cup cannot be guaranteed, which affects the follow-up process, poor use effect, and increases production costs. Contents of the invention [0003] The technical problem to be solved by the present invention is ...
