Abstract

The invention discloses a preparation technology of a disposable paper cup. Before printing, rectangular paper is subjected to corona treatment, the surface tension of the treated rectangular paper is 40-50 nM / m, the surface tension of the rectangular paper can meet requirements of printing during printing, printing quality is guaranteed, adhesion temperature and adhesion temperature of a paper board forming machine can be controlled, adhesion quality of the paper cup can be guaranteed, so that yield of the paper cup is guaranteed, after a finished product is formed, the disposable finished paper cup is placed in a disinfection cabinet and is disinfected for 6-8 hours and at the temperature of 100-120 DEG C, and the quality of the disposable paper cup can be improved. A cup body produced by the method is regular in appearance, market potential is huge, and the prospect is wide.

Description

technical field [0001] The invention belongs to the field of preparation of disposable water cups, more specifically, the invention relates to a preparation process of disposable paper cups. Background technique [0002] A paper cup is a kind of paper container made by mechanically processing and bonding raw paper (white cardboard) made of chemical wood pulp, and its appearance is cup-shaped. Waxed paper cups for frozen food, can hold ice cream, jam and butter, etc. Paper cups for hot drinks are coated with plastic, resistant to temperatures above 90°C, and can even be filled with water. The characteristics of paper cups are safety, sanitation, lightness and convenience. It can be used in public places, hotels and restaurants, and it is a disposable product. Inferior paper cups use recycled polyethylene, which will undergo cracking changes during reprocessing and produce many harmful compounds, which are more likely to migrate to water during use. In order to achieve the...
