High-performance barrier coating for recyclable flexible plastic packaging
CelluShield™ is a bio-sourced, water-based barrier coating that helps the packaging industry combine performance with recyclability. Designed for easy integration, it enables converters and brand owners to meet growing regulatory and environmental demands without sacrificing efficiency.
Features & Benefits
Performance & Sustainability
- High oxygen barrier – protects product integrity
- Enables mono-material recyclable structures
- Acts as a primer for AlOx coatings and inks
- Transparent finish – maintains branding and product visibility
- Bio-based (cellulose origin) and renewable
- Low CO2 footprint, no PFAS, no VOCs
Regulatory Advantage
- Compliant with FDA and Health Canada requirements
- Supports the EU PPWR directive and EPR programs
Seamless Integration
- Water-based & ready-to-use formulation
- Applied using reverse gravure with a target coat weight of 1 gsm
- Compatible with PE, PP, and PET
- Uses standard lamination technology
- Available as a pre-coated film for simplified supply
How CelluShield™ Works in Packaging Structures
To achieve maximum performance, the CelluShield™ barrier layer is protected between two plastic films. This multilayer structure ensures durability while delivering outstanding oxygen barrier properties.
Example 1
- Outer polyolefin layer (printable / protective)
- CelluShield™ barrier coating
- Adhesive
- Inner polyolefin sealing layer
Example 2
- AlOx layer
- CelluShield™ primer
- Plastic layer
Typical values obtained at 1 gsm CelluShield™ dry coat weight in a three-layer PE structure:
| Oxygen Transmission Rate (OTR) 50% RH, 23 °C |
< 1 cc/m2·day |
| Water Vapor Transmission Rate (WVTR) 95% RH, 38 °C |
~ 1 g/m2·day |
These structures demonstrate how CelluShield™ enables high-performance, recyclable mono-material packaging that meets strict food safety and shelf-life requirements.
CelluShield™ – Recyclable Barrier Packaging that Works
CelluShield™ empowers converters to meet brand owner demands for high-performance, fully recyclable packaging—without costly retooling or complex reformulation.
For Converters
- Mono-material, EPR-ready – Allows recyclable structures that meet EPR and PPWR requirements.
- Runs on existing equipment – Water-based coating compatible with reverse gravure and lamination lines.
- High barrier performance – Excellent oxygen protection without PVDC, EVOH, foil, or harmful chemicals.
- Flexible formats – Available as a coating or a pre-coated film.
For Brand Owners
- Circular economy ready – Supports goals for 100% recyclable packaging.
- Safe & compliant – Meets FDA and Health Canada requirements; PFAS‑free, VOC‑free, chlorine‑free.
- Bio-based & low CO2 – Made from responsibly sourced cellulose with a low carbon footprint.
- Clear & attractive – Transparent packaging that protects product quality and brand image.
CelluShield™ bridges the gap between sustainability and performance—so converters win, brand owners deliver, and consumers trust.
