Bulk bags-----For almost 20 years, we at Laizhou Yongfeng Plastics have been manufacturing the highest quality PP and PE bulk bags. Using only the highest quality resins, our polypropylene and polyethylene bags are produced to exceed the industry standards. While we may manufacture many different types of bags, they all contain some or all of the following characteristics: strong fabric and loops, Anti-seepage material, no static electricity, UV ray protection for anti-aging, and no contamination. There is no such product as "a standard" bag since majority of our products are custom designed with the assistance of our clients. Our manufacturing technology allows us to have the flexibility to produce more than 1,100 different specifications of bags.
