Problems solved by technology

[0003] The service life of the current mainstream plastic straws is only 15-20 minutes, but it takes more than 200 years to decompose into small molecules, and often cannot be completely degraded, which is extremely harmful to the environment. However, there are many paper straws made of white kraft leather. The safety and hygiene indicators cannot meet the food-grade requirements. After the tube is formed, the strength of the paper tube soaked in water is low, and it is easy to break and loose. The surface gloss of the tube is low, and the aesthetics are poor. get mouldy

Abstract

The invention discloses a paper-based material for a straw. The paper-based material for the straw comprises surface straw paper, middle straw paper and bottom straw paper, wherein the surface straw paper, the middle straw paper and the bottom straw paper are superposed and curled into a pipe shape. The paper-based material disclosed by the invention is special paper prepared with high-quality wood pulp as a main raw material and processed by using a special process without the usage of a filler. The paper-based material comprises the surface straw paper, the middle straw paper and the bottomstraw paper; and the paper straw is formed by bonding the above three paper-based materials through latex and then carrying out rolling and cutting, has the excellent characteristics of environment friendliness, degradability, no cracking, high water resistance, high antibacterial properties and the like, is diversified in styles and designs, rich and attractive in pattern, bright in color and luster and outstanding in layering sense, and is a fashionable environment-friendly material replacing plastic with paper.

Description

technical field [0001] The invention is applied in the field of environmental protection, and in particular relates to a paper-based material for straws. Background technique [0002] At present, the world consumes as many as 100 billion plastic straws every year. Although it can provide convenience for drinking, the damage to the environment, especially the ocean, is becoming more and more serious. The situation of straws replacing plastic straws has emerged as the times require, and domestic and foreign paper companies mainly use white kraft paper as the paper-based material for straws. [0003] The service life of the current mainstream plastic straws is only 15-20 minutes, but it takes more than 200 years to decompose into small molecules, and often cannot be completely degraded, which is extremely harmful to the environment. However, there are many paper straws made of white kraft leather The safety and hygiene indicators cannot meet the food-grade requirements. After ...
