Plastic woven bag placement and maintenance

The advantages and performance of plastic woven bags are more and more widely known, in the mass production and consumption at the same time, the simple maintenance of woven bags at ordinary times, place taboos also need to understand, how to reduce the aging of woven bags to a certain extent, extend the service life? Let’s first look at the anti-aging effect of woven bags monitoring.

The plastic woven bag is mainly composed of polypropylene bag and polyethylene bag. According to the sewing method, it is divided into sewing bottom bag and sewing edge bag. At present, it is widely used as a packing material for fertilizer, chemical products and other articles. The aging resistance of plastic woven bags can be evaluated by artificial accelerated aging test and outdoor exposure weatherability test. Artificial accelerated aging experiment is to place the plastic woven bag test sample in the test equipment, which can be subjected to the action of light, oxygen, heat and humidity at the same time or alternately. Under such conditions, the main environmental parameters can be relatively stable easily, so the obtained data can maintain good repeatability.

According to the above qualified products tested after uv accelerated aging, the anti-aging effect will be different in the real use environment, especially when the addition of blocked amine light stabilizer in the case of filling, the anti-aging effect is unstable. Although the outdoor exposure test of woven bags takes a long time and requires a large investment of manpower and financial resources, the obtained test data basically meet the actual use requirementsand 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 outdoor placement, rain, direct sunlight, wind, insects, ants and mice will all accelerate the destruction of the pulling quality of woven bags. Anti-flood bags, coal bags placed in the open air, etc., need to consider the anti-ULTRAVIOLET and anti-oxidation ability of woven bags themselves. Ordinary woven bags used by families or workers and farmers should be placed indoors in a place free from direct sunlight, drying and infestation by insects, ants and mice.
