ECO Friendly Coating Paper is an innovative, sustainable packaging material that combines paper substrate with environmentally friendly coatings to replace traditional plastic laminates. This specialized paper features a thin, biodegradable coating (typically 5-20 microns thick) applied to paper surfaces (ranging from 80-300 gsm basis weight) to provide functional barrier properties while maintaining compostability. The coating formulations often utilize bio-based polymers such as PLA (polylactic acid), PHA (polyhydroxyalkanoates), or water-based acrylics with >90% biodegradation within 180 days under industrial composting conditions (ASTM D6400).
Barrier Performance: Provides oxygen transmission rates (OTR) of 5-50 cc/m²/day and water vapor transmission rates (WVTR) of 10-100 g/m²/day, suitable for short-to-medium shelf life products.
Thermal Resistance: Withstands heat sealing temperatures up to 150-200°C with seal strengths of 2-5 N/15mm.
Mechanical Properties: Exhibits tensile strength of 30-60 kN/m and elongation at break of 4-15%.
Environmental Impact: Reduces carbon footprint by 40-70% compared to conventional plastic laminates, with >90% renewable content.
Printability: Supports offset, flexo, and digital printing with surface energy of 38-42 dynes/cm for optimal ink adhesion.
Compostability: Achieves 90% disintegration within 12 weeks and full biodegradation in 180 days under industrial composting conditions.
The versatility of ECO Friendly Coating Paper makes it suitable for numerous applications across industries:
Dry Foods: Ideal for packaging cereals, snacks, and baked goods with 6-12 month shelf life protection.
Fast Food Wrapping: Used for burger wraps and sandwich packaging, resisting grease penetration for 2-4 hours.
Frozen Food: Maintains integrity at temperatures as low as -18°C with minimal moisture absorption.
Cosmetics: For powder compacts and secondary packaging, providing 0.5-1.0% water vapor protection.
Pharmaceutical: Used for blister pack backing with 20-40 μm coating thickness.
Luxury Goods: High-end gift boxes with 200-300 gsm weight for premium feel.
Release Liners: Silicone-coated versions with 20-50 g/m² release force.
Labels: Wet-strength versions with 60-80 gsm basis weight for bottle labeling.
Protective Wrapping: For fragile items during shipping with 30-50% recycled fiber content.
Proper handling and storage are essential to maintain the performance characteristics of ECO Friendly Coating Paper:
Maintain relative humidity at 45-55% RH to prevent curling or moisture absorption.
Store at temperatures between 15-25°C, avoiding direct sunlight.
Keep in original packaging until use to prevent dust contamination.
Stack rolls vertically with >10 cm clearance from walls for air circulation.
Acclimate material for 24-48 hours in production environment before converting.
Use tension controls of 1-3 N/cm during unwinding to prevent stretching.
For printing, maintain ink viscosity at 20-30 sec (DIN4 cup) for optimal results.
When die-cutting, use blade angles of 30-45° with 0.5-1.0 mm penetration depth.
For heat sealing, use temperatures of 120-160°C with dwell time of 0.5-1.5 seconds.
Maintain nip pressure at 2-4 bar during lamination processes.
For cold foil stamping, use adhesive coat weights of 3-5 gsm.
When embossing, limit depth to 0.3-0.8 mm to prevent coating fracture.
For industrial composting, maintain pile temperature of 50-60°C and moisture content of 50-60%.
In home composting, turn piles weekly to ensure adequate aeration.
For recycling, separate from conventional plastics as it may require specialized pulping at 45-55°C.
In anaerobic digestion, maintain pH between 6.5-7.5 for optimal breakdown.
