High-density polyethylene (HDPE) is a common plastic with high density and strength, typically exhibiting a melt flow index ranging from 0.1 to 100 g/10min. 

Applications:

1.Packaging industry: Used to produce plastic bags, rigid containers (such as bottles for detergents, oils, and milk), and packaging films.

2.Pipe systems: Applied in water supply pipes, gas pipes, and drainage pipes because of its corrosion resistance and pressure resistance.

3.Consumer goods: Manufactured into toys, buckets, basins, and household appliances parts through injection molding.

4.Industrial applications: Used for making chemical storage tanks, liners, and protective covers due to its resistance to many chemicals.

5.Agricultural sector: Utilized in the production of agricultural films (such as mulch films) and irrigation pipes.
