Release Paper
Product
PE Coated Kraft Papers (also called PEK paper) are kraft paper substrates laminated with one or more layers of polyethylene, combining the natural strength of kraft fibre with the barrier performance of PE film. The result is a versatile packaging material that resists moisture, grease, vapour, and mechanical stress — without sacrificing print quality or process compatibility.
At TGX Group (Targanix), we manufacture PE Coated Kraft Papers to strict internal and international standards. Every roll undergoes rigorous quality control before dispatch. Explore our full release paper range or contact our team for custom specifications and pricing.
Key Features of PE Coated Kraft Papers
Moisture & Vapour Barrier
The polyethylene layer achieves ≥ 95% RH barrier performance, keeping contents dry through humid storage and transit.
Grease & Oil Resistance
Optional enhanced coatings provide up to Kit 8–12 grease resistance, ideal for meat, dairy, and oily products.
Heat-Seal Compatible
Seals cleanly at 120–160 °C, integrating seamlessly into automated form-fill-seal and lamination lines.
Full Print Compatibility
Works with flexo, gravure, water-based, and UV ink systems for sharp branding and product labelling.
Eco-Friendly Options
Recyclable kraft base and reduced-weight PE coatings available. Explore our sustainability commitments.
Fully Customisable
Single or double-side PE, 100–2000 mm widths, natural or white kraft, and custom roll diameters to order.

Storage & Processing Guidelines
| Stage | Recommendation | Reason |
|---|---|---|
| Storage – Environment | Dry, ventilated room; avoid direct sunlight | Prevents coating softening and discolouration |
| Storage – Packaging | Keep in original wrapping until use | Prevents dust, contamination, and moisture ingress |
| Pre-Processing | Acclimatise 24 hours in workshop conditions | Reduces curl and dimensional variation during conversion |
| Cutting | Use sharp, clean cutting tools | Maintains clean edges and prevents fibre pull |
| Heat Sealing | Optimise temp (120–160 °C) and dwell time by coating grade | Ensures strong seal without burn-through |
| Folding | Avoid excessive folding along the PE face | Preserves barrier integrity at fold lines |
| Handling | Prevent roll edge impacts and compression | Protects roll geometry and winding quality |
| Transportation | Covered, dry transport conditions | Maintains product condition during shipment |
