Linear Low Density Polyethylene (LLDPE)
LLDPE is a thermoplastic, further classified as a polyethylene plastic. It has a fairly low density among the thermoplastics in the database. The graph bars on the material properties cards below compare LLDPE to: polyethylene plastics (top), all thermoplastics (middle), and the entire database (bottom). A full bar means this is the highest value in the relevant set. A half-full bar means it's 50% of the highest, and so on.
