Let’s start with the material itself. Polypropylene (PP) is a thermoplastic known for its durability, moisture resistance, and flexibility. When it’s woven into strips and stitched into a bag, it gains another level of strength and utility. The weave creates a strong base that doesn’t tear easily and holds its shape even when packed to capacity.Some versions are laminated for added protection. Others include liners, custom stitches, or even anti skid layers. The fact that these options exist proves how adaptable the bags have become. It’s no longer a one-size-fits-all situation—you can get the exact configuration your product needs.
