The use of plastic woven bags and performance more and more widely known, in a large number of production and consumption at the same time, plastic woven bags at ordinary times simple maintenance, placement taboo also need to understand, how to reduce the aging of plastic woven bags to a certain extent, extend the service life? Linyi donglian plastic and we will first look at the plastic woven bag anti-aging effect of monitoring. The plastic woven bag is composed of polypropylene bag and polyethylene bag according to the main materials. According to the sewing method is divided into sewn bottom bag, sewn edge bottom bag. At present, it is widely used as a packaging material for express package, fertilizer, cement, rice, chemical products, etc. The aging resistance of plastic woven bags can be evaluated by artificial accelerated aging experiment and outdoor exposure weathering test. Artificial accelerated aging experiment is to put the plastic bag test samples in the test equipment, can be simultaneously or alternately by light, oxygen, heat and humidity and other factors, under this condition, the main environmental parameters can be relatively stable, so that the data obtained can maintain a good repeatability. According to the ultraviolet accelerated aging after the detection of qualified products, in the real use of the environment, the anti-aging effect will be different, especially in the case of adding filler to add blocked amine light stabilizer, the anti-aging effect is not stable. Although the outdoor exposure test of woven bags takes a long time and requires a large human and financial investment, the test data obtained basically meet the requirements of practical use, and can be used for the anti-aging quality evaluation and anti-aging effect monitoring of woven bags. In daily use of woven bags, the ambient temperature, humidity, light and other external conditions directly affect the service life of woven bags. Especially in the open air, rain, direct sunlight, wind, insect ants and mice will accelerate the destruction of the tensile quality of woven bags. Anti – flood bags, coal bags placed in the open air need to consider the woven bags themselves anti – uv anti – oxidation ability. The common woven bag that family or worker farmer USES, had better be put indoors the place that does not have direct sunlight, dry, do not have insect ant rat to harm, forbid sunshine insolation.
