Example Embodiment

[0018] Example 1

[0019] A method for preparing high-strength environmentally friendly plastic bags for packaging includes the following steps:

[0020] (1) Preparation of plant fiber: 20 parts by weight of plant stalks (including corn stalks and straw stalks mixed in a mass ratio of 1:3) and water accounting for 13% of the total weight of the plant stalks are added to the high-speed grinding wheel grinding system to crack Then use a high-speed decomposer to separate the above-mentioned fiber bundles into individual fibers at a speed of 5000r / min, and then use a plant fiber shearing machine to cut the individual fibers into short lengths of 5-8mm fiber;

[0021] (2) Raw material treatment: Take 10 parts of filler, 10 parts of vegetable starch, 10 parts of calcium carbonate whiskers and mix by weight, add 3 parts of silane coupling agent and 5 parts of polypropylene compatibilizer , Stir and mix evenly with a high-speed mixer;

[0022] Among them, the filler is a mixture of wood flo...

[0026] Example 2

[0027] A method for preparing high-strength environmentally friendly plastic bags for packaging includes the following steps:

[0028] (1) Preparation of plant fiber: 30 parts by weight of plant stalks (including corn stalks and straw stalks mixed in a mass ratio of 2:5) and water accounting for 18% of the total weight of the plant stalks are added to the high-speed grinding wheel grinding system to crack Then use a high-speed decomposing machine to separate the above-mentioned fiber bundles into individual fibers at a speed of 9000r / min, and then use a plant fiber shearing machine to cut the individual fibers into short lengths of 5-8mm fiber;

[0029] (2) Raw material treatment: Take 20 parts of filler, 20 parts of vegetable starch, 20 parts of calcium carbonate whiskers and mix by weight, add 5 parts of silane coupling agent and 8 parts of polypropylene compatibilizer , Stir and mix evenly with a high-speed mixer;

Abstract

The invention discloses a preparation method of a high-strength environment-friendly plastic bag for packaging. The method comprises the following steps of plant fiber preparation, raw material treatment, extrusion pelletization, film blowing forming and bag forming. The tensile strength of the plastic bag ranges from 5 MPa to 8 MPa, the elongation at break of the plastic bag ranges from 10% to 20%, and the degradation rate of the plastic bag is 90% or above. The preparation method of the high-strength environment-friendly plastic bag for packaging is simple in technology and easy to achieve, and by means of the scientific formula design and preparation technology, the prepared plastic bag has excellent structural strength and anti-shock performance, has an all-dimensional protection effect on a packaged object, has biodegradation and light degradation performance and can effectively reduce environmental pollution.

Description

technical field [0001] The invention relates to the field of plastic bags for packaging, in particular to a method for preparing high-strength environment-friendly plastic bags for packaging. Background technique [0002] Plastic bags are widely used because of their cheapness, light weight, and easy storage, and they have always occupied an important position in people's lives. However, because the traditional plastic bags cannot be degraded, they will seriously pollute the environment after being used and discarded, which greatly limits their use. At present, there are a large number of degradable plastic bags on the market, but most of them have low strength and cannot meet the requirements of use. Contents of the invention [0003] The technical problem mainly solved by the present invention is to provide a preparation method of a high-strength environment-friendly plastic bag for packaging, which can solve the above-mentioned problems existing in the existing packagi...
