Embodiment 1

[0045]Example 1: The biodegradable starch packaging material is composed of the following raw materials: 70% starch, 4% viscose staple fiber, 8% pulp board, and 18% additives. Mix the raw materials in the above ratio, add water, the ratio of water to raw materials is 52:48, stir evenly, put it into a storage tank for standby. The material in the storage tank is injected into the heated mold with an injection gun, and it is made by foam molding. The additives include 70% of asbestos powder, 20% of glycerin and 10% of liquid paraffin.

Embodiment 2

[0046] Example 2: The biodegradable starch packaging material is composed of the following raw materials: 80% starch, 3% viscose staple fiber, 6% pulp board, and 11% additives. Mix the raw materials in the above ratio, add water, the ratio of water to raw materials is 52:48, stir evenly, put it into a storage tank for standby. The material in the storage tank is injected into the heated mold with an injection gun, and it is made by foam molding. The additives include 70% of asbestos powder, 20% of glycerin and 10% of liquid paraffin.

Embodiment 3

[0047] Example 3: The biodegradable starch packaging material is composed of the following raw materials: 76% starch, 3.4% viscose staple fiber, 7.2% pulp board, and 13.4% additive. Mix the raw materials in the above ratio, add water, the ratio of water to raw materials is 52:48, stir evenly, put it into a storage tank for standby. The material in the storage tank is injected into the heated mold with an injection gun, and it is made by foam molding. The additives include 70% of asbestos powder, 20% of glycerin and 10% of liquid paraffin.

Abstract

The invention belongs to the technical field of biodegradable materials, specifically relates to a fully biodegradable starch packaging material and its processing method and equipment for implementing the method, which solves the problem that the current starch packaging materials are mainly film products, which are far from satisfying the market need. The biodegradable starch packaging material is composed of starch, viscose staple fiber, pulp board and additives. The material is mixed with water, stirred evenly, and the material in the storage tank is injected into the heated mold with an injection gun, and it is made by foam molding. The processing equipment for finished products includes storage tanks, metering pumps, injection molding guns, and injection molding machines. The packaging products produced by the method, raw materials, and equipment of the present invention have smooth surface, bright color, elegant anti-counterfeiting, non-toxic and tasteless, clear marks, uniform thickness, and have certain impact strength and toughness, and can be completely degraded without causing damage. public nuisance. The investment is small, the cycle is short, the production site is clean and hygienic, and there is no emission. Waste products and pore residues can be recycled as papermaking raw materials.

Description

technical field [0001] The invention belongs to the technical field of biodegradable materials, and in particular relates to a fully biodegradable starch packaging material, a processing method thereof and equipment for implementing the method. Background technique [0002] With the strengthening of environmental protection awareness in various countries, people's calls for environmental protection are getting higher and higher, and various industries have put forward higher and higher requirements for the manufacturing materials of product packaging. It is difficult for non-renewable or non-recyclable materials to enter the market. [0003] Although traditional plastic packaging still plays an irreplaceable role in some fields, the "white pollution" it brings has also caused great trouble to people. The replaced paper product packaging, although it has been dubbed as environmental protection, degradable, green products, etc., but the discharge of "three wastes" in the produ...
