blow molding containers

Blow-Molded Containers Provide Brands a Competitive Advantage

Polyethylene (PE) is the most widely used plastic in the world1; specifically, high-density polyethylene (HDPE) is the most common resin used in the extrusion blow molding (EBM) process2. The semi-crystalline, solid-state structure of HDPE offers unique properties like:

  • Rigidity
  • Toughness
  • Impact resistance
  • Moisture and chemical resistance

These features make HDPE ideal for various blow-molded products such as household and industrial cleaners, milk jugs, lotion bottles, and more. HDPE's unique properties combined with low cost and ease of fabrication, make this resin common for use in everyday products.

Blow molding PE allows plastic converters to quickly make large quantities of cost-effective, aesthetically pleasing containers that will last a long time.

 

Key Markets for Blow-Molders

Food and Beverage

Blow molders actively participate in the fast-growing food and beverage industry by producing liquid food, dairy, water, and sports nutrition bottles.


Household & Industrial Chemicals

Blow molders need to provide customers with containers for household and industrial chemicals that are tough enough to resist leaks and breaks.


Personal Care

Blow-molded HDPE is commonly used to create vessels for personal care items such as shampoo, cosmetics, and dish soaps.
