Polypropylene bags are more accurately referred to as “woven” polypropylene (PP) bags. Manufacturing the woven fabric used to make PP bags includes:
- Melting the raw polypropylene pellets.
- Extruding the melted PP pellets into flat thin sheets.
- Cutting the extruded PP sheets into thin tapes.
- Rolling the long PP tapes onto bobbins.
- Weaving the PP fabric from the bobbins loaded on the circular or flat weaving loom.
Weaving is a method by many threads or tapes woven in two directions (warp and weft), to form a fabric for plastic industry needs.
In the plastic woven industry, with a plastic film is drawn into filaments, woven into fabric sheet or cloth. Woven PP fabric can be cut and sewn into bulk bags, small PP sandbags, tarps and shopping bags.
