Oxygen barrier
EVOH can provide strong oxygen-barrier performance within an engineered multilayer structure.
High barrier packaging
High Barrier EVOH COEX Packaging
Multilayer bottle and container development for projects that need more protection than a standard monolayer structure can provide.
Barrier technology
Engineer the structure around the filled product
EVOH is used as a functional barrier layer within a multilayer COEX structure. The final layer arrangement, resin selection and thickness are confirmed project by project.
Reduced permeation
The selected COEX structure can help control permeation for compatible formulations and storage conditions.
Chemical resistance
Layer selection is reviewed against the formulation, concentration, closure and intended service life.
Product protection
Barrier, container geometry and closure are evaluated as one packaging system.
Potential applications
For sensitive liquid packaging projects
- Selected agrochemical formulations
- Industrial chemicals and additives
- Food ingredients and sensitive liquids
- Products requiring controlled oxygen transmission or permeation

Technical answers
Frequently asked questions
What does EVOH add to a plastic packaging structure?
EVOH can provide a high oxygen barrier within a multilayer COEX structure and can help reduce permeation for compatible products. The complete structure must be selected for the specific formulation and use conditions.
Is every existing mould available with EVOH COEX technology?
No. COEX availability is model- and project-specific. EIPS reviews the required structure, mould, production route and order volume before confirming feasibility.
Which applications may benefit from high-barrier packaging?
Potential applications include selected agrochemicals, chemicals, sensitive industrial liquids and food ingredients. Final suitability depends on formulation, concentration, storage period, temperature and closure system.
