4-Layer COEX Technology
"Why Multilayer Matters"
Multilayer barrier packaging uses polymers with high barrier qualities alongside the specific attributes each product's packaging needs. 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.
How Blown Coextrusion Works
Blown coextrusion is the process of simultaneously extruding two or more polymers to create a single, unified container with multiple distinct layers.
Each layer serves a purpose. One layer carries the barrier material itself, while others provide structural strength, chemical resistance or specific performance attributes the product requires.
The result is a single container with up to 4 layers of protection — engineered based on what your product needs to survive.
- Multiple extruders working simultaneously
- Barrier material carried by a dedicated layer
- Up to 4 distinct layers of protection
- Layer structure engineered around product needs
Sustainability Built In
Better packaging, less material, smaller footprint
Recyclable Containers
Designed for recyclability — subject to confirmation of the exact product and recycling specification.
No Separation Needed
No separation required between treated and untreated packaging for recycling — confirm applicability.
Lightweighted Design
Less plastic per container, lower transport cost and a smaller overall footprint.
