The aging of the ton bag is mainly due to the formation of ultraviolet light in the sun, which causes the degradation of polypropylene, so that the ton bag presents a decrease in tension, powder, fading and other appearances. On the basis of the aging elements and the aging inspection specifications, all customers can be satisfied with the anti-aging needs of ton bags. How to improve the anti-aging effect of all tons of bags?
The first point: to fully understand the customer's needs for anti-aging ton bags, such as the use of address, the use of time cycle, etc., some customers will provide artificial accelerated aging test time and retention strength, some customers mark the increase of UV additives, according to the needs of customers, develop the product technical plan.
The second point: planning the production formula. Due to the aging of the recycled material, the cracking of the molecular chain, the mechanical properties have been reduced a lot, and the use time has been sharply shortened, and it is necessary to choose new materials for raw materials.
Third point: For the anti-aging masterbatch that improves the aging resistance of tons of bags, customers should be stable and investigated, although the increase is small, it is very crucial, it is necessary to put forward strict requirements for the anti-aging masterbatch suppliers to fully ensure the quality of the goods.
Fourth point: a good ton bag contains base cloth, sling, material cloth and sewing thread, which must meet the needs of anti-aging, if a problem, severe results will occur, many users have suffered similar experience.
Ton bags are not high value things, can be said to be high consumables, but we also have to take measures to slow down the aging.
