The below two elements are effect to the pp woven bag's quality:
1.Material quality
Plastic woven bags are made of PP polypropylene particles. They are generally divided into new materials and recycled materials. As the name suggests, the tensile strength and transparency of new materials are much better than recycled materials. The appearance of new material woven bags is generally uniform and bright in color, and has very good toughness and tensile strength. The quality of recycled material woven bag is also measured based on the degree of recycling of recycled materials and the quantity of masterbatch added. The toughness and tensile strength of low-priced recycled materials will be much reduced.
2. Weight
The quality of woven bags is inseparable from the weight. Generally speaking, the weight more higher, the bag more thicker , and the quality more better. The export quality of the plastic woven bags produced by our company generally ranges from 130g/㎡ to 160g/㎡. The square gram weight directly determines the thickness and strength of the woven bag. For China domestic market most jumbo pp woven bags are based one 110g/㎡ or less.
The quality of woven bags is mainly measured through these two parts, material quality and weight. The material quality determines the tensile strength and toughness of the bag, and the weight determines the thickness and density of the bag. In real life, various woven bag factories produce The appearance of woven bags looks very similar but they are very different. This is mainly due to the issue of how much masterbatch is added. If more masterbatch is added, the tensile force of the bag will decrease. This is what is generally used when comparing woven bag products from different manufacturers.
