Preparation technology of disposable paper cup

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
