What Is The Aging Of Woven Bags Related To

In our daily life, we can often see the use of plastic woven bags, which are widely used for packaging and express delivery, grain storage, transportation of goods, etc. However, many customers and enterprises often ask this question when purchasing woven bags: Why do woven bags age? How to avoid aging of woven bags?

The woven bag factory teaches you: What are the reasons for the aging of woven bags? The woven bag factory has sorted out several reasons for the aging of woven bags:

1. Polypropylene is a material that is easy to draw. Although polyethylene can also be drawn, it is relatively more difficult. Therefore, the large amount of polypropylene woven bags is also a major reason.

2. Woven bags are basically disposable products, especially for new products, which are not easy to use again. In order to reduce costs, the price of polypropylene is more appropriate.

3. In order to better reduce the market sales price of woven bags, a part of calcium carbonate will be added to the raw materials to calcium polypropylene, which will greatly reduce costs and enhance market competitiveness.

4. It is precisely because calcium carbonate is added to the polypropylene woven bag that it is easy to age and weather when it is placed outdoors.

The above is about the reasons for the weathering of woven bags. After absorbing ultraviolet light, woven bags will be stimulated and dissociated to produce free radicals, which will lead to aging. The woven bag manufacturer reminds that the woven bag can be recycled, but the polypropylene in the recycled woven bag has produced active free radicals such as hydroxide, so re production and manufacturing will accelerate the degradation and aging of polypropylene. Therefore, when not in use, we should remember to store woven bags, paper plastic composite bags, etc. to avoid direct contact with the sun.
