The woven bags generally is made from polypropylene or polyethylene.  polypropylene and polyethylene molecules in the sunlight and easy to accelerated aging and decomposition under the irradiation of ultraviolet light,  long time outdoor exposure, it's easy to let the bag lost use value.  Many woven bags need to be in daily use outdoor long-term exposure or used in the environment of high UV.  So we will need to use to Anti - UV Woven Bags.  Anti - UV Woven Bag  is in the process of production to join the resistance to UV stabilizer,  The polypropylene or polyethylene molecules is relatively stable under the sunlight or ultraviolet light .  Under normal circumstances,  Anti - Uv Woven Bags in the sunshine of life is much higher than the ordinary woven bag,  anti - UV woven bag is in high sunlight or ultraviolet light environment service life can reach six months to a year, during this period,  the performance of anti - UV woven bags will not change.
