Can PP woven bags be used in food? The answer is yes. The quality of the woven bag itself is recognized. It can hold cement, food and some sundries. However, the woven bag for food needs to be lined in order to ensure that the food will not be affected when it is stored. Just like our common chemical fertilizer packaging, pet feed packaging, etc., there are lining inside. Those without lining are specially treated bags, which can achieve the purpose of waterproof.
Reducing the weight of packaging is the basis of material development. Reducing the weight means reducing the input of certain raw materials, which can achieve the effect of energy saving and emission reduction, so as to achieve the role of environmental protection.
However, PP woven bags can't be mixed because of different product positioning, just like those containing fertilizer can't contain feed, even if they are cleaned, it's because of the material of the bags themselves.
