New improved SecureFit360® HD liner bags are more rigid to provide a better formed fit, making installation and removal easier and more efficient. The frosted color masks the contents yet still allows cleaning staff to see and avoid potential needles and other sharps. The heat seal at the top strengthens the built-in wrap around strap and makes it appear neater on the receptacle. Not only is the thinner high density bag made with considerably less plastic than the original low density SecureFit360®, it sends 50% less material weight to a landfill than Kraft waxed paper bags. The 12 um THK adds maximum strength and performance.
