"Case Qty. 4,000- Tuf-RŪ bags are made from a unique blend of linear low density (LLD) resin. This material allows bags to be of a thinner gauge while still providing the same or better strength and puncture resistance as a standard low density bag of a higher gauge. Tuf-RŪ bags also meet FDA requirements for use in food applications and are a cost effective alternative when compared to a standard low density bag. Bottom sealing gives them added strength."
