It’s essentially a thermoplastic, implying that it can be molten and remolded into the desired shape making it reusable and cost-effective. Of all the different kinds of plastics produced around the world, polyethylene is the most common and significant.

Polyethylene is manufactured in three different forms namely:

Low Density Polyethylene (LDPE),High Density Polyethylene (HDPE) andLinear Low Density Polyethylene (LLDPE),

Each of these three plastics has different applications ranging from containers, packaging and films to buckets and bottles.
