What plastic is used in shampoo bottles?

Shampoo bottles are typically made from one of the following types of plastic:

1. High-Density Polyethylene (HDPE): 

This is the most common plastic used for shampoo bottles. It is strong, durable, and resistant to impact, which makes it suitable for packaging liquids. HDPE is also recyclable.

2. Polyethylene Terephthalate (PET or PETE): 

PET is another common plastic used in shampoo bottles. It is lightweight, clear, and has good moisture barrier properties. PET is also recyclable and often used for clear shampoo bottles to showcase the product inside.

3. Polypropylene (PP): 

PP is sometimes used for shampoo bottles, especially for the caps and closures. It is rigid and has a high melting point, making it suitable for hot-fill applications.

These plastics are chosen for their durability, resistance to chemicals, and ease of molding into various shapes and sizes. Additionally, many manufacturers aim to use recyclable materials to reduce environmental impact.
