Material Composition & Environmental Safety Water-Based Ink Compatibility: Surface-engineered with corona treatment (≥38 dyne/cm) to optimize adhesion and ink anchorage for water-based inks. The substrate features hydrophilic properties that align with the polar nature of water-based inks1 Eco-Friendly Profile: Free of phthalates, PVC, and volatile organic compounds (VOCs), complying with REACH, ROHS, and FDA 21 CFR §177.1520 for direct food contact. Supports sustainability goals by enabling recyclable mono-material packaging streams1 Ink Formulation Adaptability: Compatible with water-based inks containing water-soluble acrylic resins, organic pigments, and additives (e.g., silicone surfactants at 0.005-0.3% mass). Ensures stable pH (8.0-9.5) to prevent plate corrosion1 Functional Performance Print Quality & Durability: Delivers **≥90% light transmittance and high-resolution prints (up to 1440 DPI) with abrasion-resistant surface coatings**. Maintains color vibrancy and resists fading under UV exposure3 Rapid Drying & Processing: Optimized porosity and anti-fog coatings enable drying speeds of 150-200 meters/minute (hot air/IR systems), reducing production downtime5 Barrier Properties: Engineered OTR ≤5 cm³/m²·day·atm and WVTR ≤2 g/m²·day (ASTM F1249) to protect contents from moisture/oxygen ingress, extending shelf life4 Processing Efficiency Automation Compatibility: Pre-cut widths of 200-1,200 mm (±0.2 mm tolerance) and roll lengths up to 5,000 meters. Compatible with VFFS machines at ≥180 bags/minute without jamming4 Heat Seal Performance: Seal initiation temperature ≤110°C and seal strength ≥25 N/15mm (ASTM F88), ensuring leak-proof closures for granular/powdered products Product Specifications Physical Parameters Thickness Range: 25-200 μm (customizable for flexo/gravure printing applications)4 Surface Tension: 38-45 dyne/cm (corona-treated), validated per ASTM D25784 Roll Dimensions: Core ID 76.2 mm (3") or 152.4 mm (6"); max. outer diameter 1,200 mm9 Printing Performance Ink Adhesion: **≥95% ink retention after tape test (ASTM D3359), suitable for PE, PP, PET, and paper substrates**1 Viscosity Adaptation: Optimized for water-based inks with viscosity 0.1-1.0 Pa·s (Newtonian fluid behavior)2 Color Gamut: Supports 10-color gravure/flexo printing with ΔE ≤2.0 color accuracy (ISO 12647-2)7 Barrier & Mechanical Properties OTR: ≤5 cm³/m²·day·atm (23°C, 0% RH; ASTM D3985) WVTR: ≤2 g/m²·day (38°C, 90% RH; ASTM F1249)4 Tensile Strength: ≥50 MPa (MD), ≥40 MPa (TD) (ASTM D882)8 Puncture Resistance: ≥50N (ASTM F1306)8 Certifications & Compliance Food Safety: FDA 21 CFR §177.1520, EU 10/2011; heavy metal migration <0.01 ppm1 Sustainability: GRS 4.0 (recycled content ≥30% options), ISO 14067 (carbon footprint ≤1.5 kg CO/kg)7 Quality Management: ISO 22000, BRCGS Packaging Materials
