Polyethylene (PE) is a crystalline plastic produced from the polymerization of ethylene.    
PE has the features of (1) lower specific gravity, (2) chemical stability and water and chemical resistance, (3) excellent strength and flexibility (soft and bendable) and (4) high formability. 
PE is classified into High Density Polyethylene (HDPE or PE-HD), Low Density Polyethylene (LDPE or PE-LD) and Linear Low Density Polyethylene (LLDPE or PE-LLD). 
HDPE (PE-LD, High Density Polyethylene): Has excellent water and chemical resistance and relatively high resistance to hot and cold temperatures.
LDPE (PE-LD, Low Density Polyethylene): Has excellent flexibility, and water and chemical resistance.
LLDPE (PE-LLD, Linear Low Density Polyethylene): Has higher tensile strength and cold temperature resistance.
