Description

technical field

[0001] The invention relates to a process flow of a paper straw, in particular to a process method for bending and beveling a paper straw. Background technique

[0002] Straw, as a common object used to drink beverages in cups in daily life, is generally made of plastic in industrial production. The liquid after the plastic is melted is injected into the mold, and it is formed after cooling. Nowadays, people pay more and more attention to the concept of health and environmental protection. In order to solve people's needs, paper straws came into being.

[0003] The Chinese patent with the publication number CN109463964A discloses a paper straw, which includes a first paper layer and an adhesive attached to the first paper layer, and then the first paper layer is bonded to the second paper layer , the first paper layer is spirally wound to form a tube. This paper straw has better water repellency, oil repellency and better acid resistance.
