Monitoring of anti-aging effect of woven bags

Plastic woven bags are mainly composed of polypropylene bags and polyethylene bags; According to the sewing method, it is divided into sewing bottom bag and sewing edge bottom bag. At present, it is widely used as a packaging material for fertilizers, chemical products and other goods. The aging resistance of plastic woven bags can be measured by artificial accelerated aging test and outdoor exposure weather resistance test. Artificial accelerated aging experiment is to put the plastic bag test sample in the test equipment, which can be affected by light, oxygen, heat and humidity at the same time or alternately. Under this condition, the main environmental parameters can easily remain relatively stable, so the obtained data can maintain good repeatability.
According to the above ultraviolet accelerated aging products tested, in the actual use of the environment, the anti-aging effect will be different, especially when adding filler to add hindered amine light stabilizer, its anti-aging effect is not stable. Although the outdoor exposure test of woven bags takes a long time and has a large investment in human and financial resources, the test data basically meet the actual use requirements, and can be used for the anti-aging quality evaluation and anti-aging effect monitoring of woven bags.
