We hope to be able to control the aging of the container bags. Because of the safety of transportation materials, the general aging life of the container bags is required to reach half a year or even more. Some customers will provide the test time and final retention strength of artificial accelerated aging, and even some customers have indicated the addition amount of UV additives, and according to the requirements of customers, formulate the technical scheme of products. Design the production formula. Because the recycled material has been aged, the molecular chain has broken, the mechanical properties have declined greatly, and the service life has been shortened dramatically, the raw material must be brand-new.
