Woven Polypropylene (WPP) Sacks

WPP sacks are strong and durable, making them ideal for products like metal fixings, plastic parts, textile and paper recycling, animal feeds and more.

They’re made from PP (polypropylene), a high-strength thermoplastic that’s incredibly flexible. The PP is extruded in tubular form, and then cut into threads that when woven together (warp and weft) form a very strong fabric. The sack is then hemmed to stop it fraying.

There’s also the option to coat the woven polypropylene fabric with a thin PE layer to make your sack waterproof.
