Analysis of the causes of brittle brittle plastic woven bags

Plastic woven bags are widely used in agriculture, industry and daily life because of their lightness, durability and relatively low production cost. However, sometimes we find that these bags can become brittle and brittle under certain circumstances. What causes this? Chengdu woven bag manufacturers below to carry out an in-depth discussion and analysis.

Material aging

Plastic woven bags are made of polypropylene or other plastic materials. Under the action of long-term light, high temperature and oxygen, these materials will undergo oxidation reactions, resulting in gradually brittle materials. Especially in the environment of high temperature and high humidity, the aging speed of woven bags will be accelerated. Therefore, for long-term storage of woven bags, should be placed in a cool, dry place as far as possible to slow the aging of materials.

Stress concentration

During the production of plastic woven bags, stress concentration may occur in some parts. These stresses will gradually be released during the use of the woven bag, resulting in cracks or breakage of the woven bag. In order to avoid this situation, it is recommended to avoid severe bending or folding when using woven bags.

Low temperature environment

At low temperatures, the toughness of plastic materials will be reduced and become fragile. Therefore, special care should be taken when using woven bags in cold winter or low temperature environments. Try to avoid long-term exposure to the outdoors at low temperatures to prevent the woven bag from breaking due to low temperatures.

Chemical corrosion

Plastic woven bags may be damaged by corrosion if they come into contact with certain chemicals, such as organic solvents, strong acids and alkalis. Therefore, when using woven bags, contact with these chemicals should be avoided to prevent woven bags from becoming brittle and fragile due to chemical corrosion.

Manufacturing process problem

Some plastic woven bags may have process problems in the manufacturing process, such as improper material ratio, unreasonable weaving process, etc., resulting in poor quality of woven bags and easy to be brittle and fragile. In order to ensure the quality of woven bags, manufacturers should strictly control the manufacturing process and material ratio.

In summary, there are many reasons for the brittleness of plastic woven bags, including material aging, stress concentration, low temperature environment, chemical corrosion and manufacturing process problems. In order to extend the service life of woven bags, the above adverse factors should be avoided as far as possible. At the same time, when purchasing woven bags, users should also pay attention to choosing good quality products to ensure their service life and safety.
