A.K.A. Carrier bag, poly bag

Low Density Polyethylene (LDPE) is softer, smooth and shinier than HDPE, and slightly elastic so it is not as strong. It is less dense because of the increased space between the few branches that form during polymerisation, which makes it more flexible. LDPE also has better clarity than more dense polyethylene materials, so it can be used as a packaging option that lets consumers easily see what’s inside. And, LDPE is easy to tear, which is a strength when packaging needs to be easy to open.
