These trash bags are made from LLDPE (linear low-density polyethylene), which is a plastic that stretches to conform to waste and resists tears, impacts, and punctures. They hold discarded items that have sharp corners or edges, including glass shards, sticks, and broken-down cardboard.

Trash bags for soft refuse are made of HDPE (high-density polyethylene), which is a lightweight plastic that may tear from contact with sharp corners or edges. These bags hold discarded items with soft or rounded edges, such as paper towels, paper, and fabric.

These trash bags resist tears and punctures and can hold heavy or sharp trash such as wood, metal, and concrete. Polypropylene bags do not stretch and are stronger and less likely to puncture or tear than super hexene HAO bags. They are also known as contractor bags and can be reused multiple times. Super hexene HAO bags are stronger and less likely to puncture or tear than LLDPE or HDPE bags, and they stretch to conform to waste with sharp corners or edges.
