COEX Bottles

Multilayer protection engineered for demanding formulations.

Multilayer, co-extruded bottles built for products that can't afford to degrade. Using blown coextrusion technology, we combine multiple polymers — including high-barrier materials — into a single container with up to 4 protective layers.

Multilayer COEX Technology

Through blown coextrusion — simultaneously extruding two or more polymers — multilayer packaging is built using multiple extruders, one of which carries the barrier material itself.

Depending on what your product needs to survive — moisture, oxygen, chemical exposure or temperature swings — containers can be built with up to 4 layers of protection.

  • Up to 4-layer barrier protection
  • High-barrier polymer integration
  • Chemical-resistant HDPE construction
  • Available in multiple shapes and sizes
