Description

Water-resistant smooth paper straw

Technical Field

The utility model relates to a paper straw production technical field, concretely relates to water-fast smooth paper straw.

Background

The straw is an article which is frequently used by people and is widely applied to the life of people, however, the existing straw is made of plastic, when the straw meets high temperature and other substances which are easy to react with the straw, the straw easily releases substances which are harmful to human bodies and can cause bad influence on the health of the human bodies, and the existing straw is a disposable plastic product, has no value of reutilization after being used and cannot be degraded.

The use of plastic straws is prohibited from all sides in 2021 in China and European Union, the paper straws are the best products for replacing the plastic straws at present, and the paper straws on the market at present have the following defects:

1. the water resistance of the paper drinking straw is very poor and the paper drinking straw is easily softened when contacting with liquid beverage.

2. The paper straw has rough and unsmooth surface and poor taste when being sucked and drunk.

3. The printing ink on the surface of the paper suction pipe is easy to fade when being impregnated by liquid.

The applicant researches and discovers the following reasons:

1. the paper suction pipe is made of bamboo fiber paper which meets the food standard, the bamboo fiber paper has microscopic pores, and liquid can quickly permeate into the paper fibers after contacting with liquid beverage, so that the suction pipe is softened and loses hardness and stiffness.

2. Because bamboo and wood fibers have pores, the surface of the paper is rough and not smooth, and the taste of the paper is not smooth like a plastic straw when the paper is sucked.

3. The paper straw surface pattern printing adopts environment-friendly food-grade ink, the adhesion force of the food-grade ink and paper is not high compared with that of common ink, and the paper straw surface pattern printing has a fading phenomenon when being soaked in liquid.

SUMMERY OF THE UTILITY MODEL

In view of the above, the present invention is directed to a water-fast and smooth paper straw, which solves the problems of easy softening, rough surface, poor taste and fading of ink in the contact between the paper straw and liquid.

In order to realize the technical purpose, the utility model discloses a scheme is:

preferably, the water-resistant smooth paper straw comprises a paper layer, and is characterized in that: the paper layers are arranged into four groups, a waterproof adhesive film is arranged between each group of paper layers, the surface of the outermost paper layer is coated with a food-grade smooth waterproofing agent, and the inner wall of the innermost paper layer is coated with a food-grade smooth waterproofing agent.

Preferably, the method is characterized in that: the thickness of the outermost paper layer is smaller than that of the other three paper layers.

The utility model has the advantages that:

1. the utility model discloses to the smooth waterproofing agent of bamboo wood fiber paper surface coating food level, make the paper have the function of separation liquid infiltration, improved the water resistance performance of paper straw, be difficult to soften.

2. The food-grade smooth waterproofing agent coated on the surface of the paper has the effects of brightness and smoothness, and the drinking taste is improved.

3. The paper with patterns printed on the surface is coated with the food-grade smooth waterproofing agent, so that the penetration of liquid into the paper is blocked, the printed patterns on the surface of the paper suction pipe are protected from being infiltrated by the liquid, and the problem of fading of the printing ink is solved.
