Problems solved by technology

[0003] At this stage, with the development of society, there is an increasing demand for paper trays ranging from household appliances and machinery to fruits and bowls. The mass production of paper trays has caused a large number of felling of trees, resulting in waste of resources and environmental pollution.
[0004] And the paper tray made of white wood pulp or discarded carton newspapers often has poor solvent resistance. For example, when some cold drinks are placed, the shockproof effect of the paper tray will be greatly affected due to water soaking; and the paper tray itself The smell of wood pulp will also produce a bad user experience when used in the food field

Abstract

The invention belongs to the technical field of packaging, and particularly relates to a tea residue paper support and a preparation method thereof. The preparation raw materials comprise raw wood pulp, tea leaf residues, cellulose, soybean meal and water. By adjusting the mass ratio of the tea residues to the cellulose to the soybean meal, the bursting strength of the tea residue paper support can be improved, then the service life of the tea residue paper support can be prolonged, and the production cost is reduced; green tea leaf residues are selected, so that the acting force among the tealeaf residues, cellulose and soybean meal can be enhanced, and the wood pulp taste on the surface of the paper tray is improved; and the tea leaf residues with the particle size of 100-200 meshes areselected, so that the enhancing effect of the tea leaf residues on the performance of the paper support is improved on the premise of ensuring good dispersity.

Description

technical field [0001] The application belongs to the technical field of packaging, and more specifically relates to a paper holder for tea leaves and a preparation method thereof. Background technique [0002] Molded pulp tray, also known as pulp mold, is made of newsprint, white pure wood pulp, etc., after pulping and blending into a certain concentration of slurry, and then according to product requirements and design, it is formed by vacuum adsorption. After drying to form environmentally friendly paper products of different types and uses. It has good shockproof, shockproof, antistatic, anticorrosion and other effects. It is widely used in the four major fields of industrial paper trays, agricultural paper trays, food paper trays and medical products. [0003] At this stage, with the development of society, there is an increasing demand for paper trays ranging from household appliances and machinery to fruits and bowls. The mass production of paper trays has caused a ...
