HDPE Plastic Bags, also known as shopping bag OR T-shirt bag , are affordable thermoplastic polymers with a straight structure with little to no degree of branching. It is manufactured at low temperatures ranging from 70ºC to 300°C and pressures ranging from 10 to 80 bar. It is obtained through the catalytic cracking of crude oil into gasoline or modifying natural gases such as ethane, methane, or propane mix.

LDPE Plastic Bags, also known as Low-Density Polyethylene (LDPE), is a soft and flexible polymer. It has a lower density, strength, and temperature resistance than HDPE plastics.
