Used to make hollow products such as dairy bottles, industrial containers and drums, liquid containers, and more, blow molders are among the largest users of high-density polyethylene.
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:
- 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
Blow molders actively participate in the fast-growing food and beverage industry by producing liquid food, dairy, water, and sports nutrition bottles.
Blow molders need to provide customers with containers for household and industrial chemicals that are tough enough to resist leaks and breaks.
Blow-molded HDPE is commonly used to create vessels for personal care items such as shampoo, cosmetics, and dish soaps.
On-site Blow Molding Equipment in Applications Hall
To set our technical service team up for success, we're filling the applications hall with state-of-the-art commercial equipment. As a result, customers can work hand-in-hand with our experts on our machines to test or qualify resin without having to shut down their business’ production lines.
The application hall will have two industrial-sized blow-molding machines:
- A Kautex electric, continuous extrusion shuttle machine equipped with a mono-layer and multilayer flow head that manufactures containers of different sizes
- A Uniloy hydraulic, reciprocating screw, machine equipped with a mono-layer head that produces containers for dairy applications
