TUF-R® Linear Low Density Polyethylene (LLDPE) plastic bags provide extra strength and puncture resistance compared to Low Density bags of the same gauge. Because of this, it is possible to use a lighter gauge TUF-R® bag to do the job of a heavier gauge LDPE bag, which saves money and helps to reduce the environmental impact. TUF-R® bags are made from virgin materials, so they comply with FDA requirements for use in food applications. Made from seamless tubing with no slits or side seals that can rip.
