The aging of tons of bags is mainly due to the formation of ultraviolet light in the sun, ultraviolet light caused the degradation of polypropylene, so that tons of bags show tension reduction, powder, fading and other appearances, the value of tons of bags is not high, a general ton of bags is a few dollars, but the material is thousands of times or even tens of thousands of times the value, so the safe use of tons of bags is a very important issue.
In order to transport the safety of materials, the general aging resistance of tons of bags is required, reaching half a year or even more, of course, depending on the specific needs of customers in fully understanding the mechanism of aging of tons of bags, the elements of aging and the specifications of aging inspection of tons of bags, on the basis of which all customers can be satisfied with the anti-aging needs of tons of bags.
Here are some suggestions for further preventing the aging of tons of bags:
First: To fully understand the customer's needs for anti-aging of tons of bags, such as the use of address, the use of time cycle, etc., some customers will provide artificial accelerated aging test time and final retention strength, and even some customers will mark the increase of UV additives, according to customer needs, develop product technical plans
Two: Planning the production formula.
Due to the aging of recycled materials, molecular chain cracking, mechanical properties have been greatly reduced, the use of tons of bag base cloth life is sharply shortened, raw materials are necessary to choose new materials to deal with the aging of tons of bags, it is necessary to increase anti-aging additives in accordance with a certain proportion if the use of UV additives will make the dispersion of materials difficult to deal with, the formation of technical processing is difficult, And anti-aging masterbatch can be useful to deal with this question.
For the color of the product, according to customer requirements, choose different fast grades of color masterbatch
Three: For the anti-aging masterbatch that improves the aging resistance of tons of packages, customers should be stable to investigate, although the increase is small, but the effect 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
Four: a ton of sound bag base cloth contains the base cloth, sling, material cloth and sewing thread, which must meet the needs of anti-aging, if a problem occurs, severe results will occur, many users have been subjected to similar experience.
