Turn your flexible packaging line into a platform for high-value structures without unnecessary plastic
Design pouches, films, and flexible structures with oxygen barriers, adhesion primers, and heat seals to replace hard-to-recycle multilayer materials with sustainable mono-material solutions.
High oxygen barrier
OTR < 0.8 cc/m²/day for oxygen-sensitive foods.
Recyclable mono-material
Remove EVOH or aluminum layers for PE/PE or PP/PP structures.
Technical validation included
Support from pilot trial all the way to industrial scale.
What a flexible packaging manufacturer can achieve with Coaterex
Convert sustainability and performance demands into new high-margin products. Our technical routes help you differentiate without changing your converting line.
Replace multilayer structures with EVOH or aluminum
Move to mono-material structures with high-efficiency water-based barriers that preserve product shelf life.
Improve adhesion in printing and lamination
Apply primers optimized for flexo, gravure, or extrusion and ensure robust bonding in every structure.
Add low-temperature heat seals
Reduce sealing energy consumption and expand substrate compatibility with next-generation heat seal coatings.
Design structures for digital flexible packaging
Combine HP Indigo-certified primers with functional barriers for digitally printed pouches ready for market.
What changes in your structure
The same protection, with a material recyclers can actually recover.
Today
Multi-material laminate
- Printed PET film

Product families to build your offer
Each family solves a specific technical challenge. Combine them to create differentiated structures that your customers cannot find anywhere else.
Primers and adhesion promoters
For printing, lamination, extrusion, and metallization. The starting point for any high-performance flexible structure.
Advanced oxygen and moisture barriers
Replace EVOH and aluminum with high-efficiency water-based barriers for recyclable mono-material structures.
Heat seals and sealants
Reliable sealing on a wide range of substrates. Control seal strength, activation temperature, and opening behavior.
Surface resistance and finishes
Protect inks and substrates against abrasion, chemicals, and heat. Improve performance on converting line and logistics.
How to implement a solution with the lowest possible risk
Define the functional target, choose the right technical route, and validate in pilot before scaling production.
Key technical controls
- OTR (ASTM D3985): oxygen transmission of the coated film.
- WVTR (ASTM F1249): water vapor transmission rate.
- T-peel / Lap-shear: lamination and seal bond strength.
- Hot-tack: seal resistance under heat during filling.
Implementation steps
- Define base substrate, packed product, and real use conditions.
- Prioritize functional goal: barrier, adhesion, sealing, or surface finish.
- Select product and application method for your current equipment.
- Validate impact on printability, lamination, line speed, and sealability.
- Run pilot trials controlling coat weight and curing parameters.
- Document results to scale production with stability and repeatability.
