PP Woven Bag Technology Principles

Technically speaking, PP woven bags are made by a series of processes including melting, extrusion, stretching, and weaving of polypropylene granules. In this process, the polypropylene granules are heated to a molten state, then extruded into a film using an extruder. The film is then stretched to give it a certain strength and toughness, and finally woven into a bag using a weaving machine. This production process gives PP woven bags both the flexibility of plastic bags and the strength and durability of woven bags.
