PP L5E89 is a widely recognized raffia-grade polypropylene (PP) homopolymer specification in the Asian market. It is primarily used for extrusion and weaving applications, including woven bags, FIBC (jumbo bags), ropes, and injection-molded household products.

It is important to note that “L5E89” refers to a grade specification rather than a single proprietary brand. Multiple petrochemical producers manufacture and market PP under the L5E89 designation, each supplying material under their own corporate brand.
