HDPE Plastic

HDPE is used to make many types of packaging. It is most notably used to make packaging bottles for products with a short shelf-life, like milk. Natural HDPE is semi-transparent, and has excellent barrier and rigidity properties. As a result of HDPE’s excellent chemical resistance, it is used for packaging many household and industrial chemicals such as detergents and bleach. In thermoforming applications HDPE is commonly used where durability and/or cushioning are required.
