What materials are used to make a shampoo bottle?

Common plastic materials used for shampoo bottles include:

  • PET. PET is a clear plastic material.
  • LDPE. LDPE plastic is highly flexible, squeezable, and durable.

  • MDPE.
  • PVC.

How are HDPE shampoo bottles made?

What is the difference between PP and HDPE?

Density is a key factor that differentiates HDPE from PP. Because HDPE has a lower density, it can be more rigid. Thanks to its lower density, though, PP, can be used when moulding parts with lower weight. Like HDPE, Polypropylene offers good chemical resistance.

What are the 2 types of plastics?
