| General Specifications |
• Product Type: Stand-up spout pouch with heat-sealed closure • Application: Chocolate sauce, syrups, and viscous liquid packaging • Capacity Range: 200ml–5L (customizable) |
| Material Structure |
• Base Laminate: PET (12μm) / Adhesive / Nylon (15μm) / EVOH Barrier (6μm) / LDPE (70μm) • Barrier Properties: EVOH layer reduces oxygen transmission rate (OTR) to ≤0.05 cc/m²/day at 23°C, 0% RH
• Sealant Layer: Food-grade LDPE for hot-fill compatibility |
| Thermal Resistance |
• Hot-Fill Tolerance: 120°C for ≤30 seconds without deformation/delamination • Post-Fill Stability: Maintains seal integrity during rapid cooling (100°C → 25°C in ≤5 mins) • Operational Range: -40°C to 130°C (short-term exposure) |
| Barrier Performance |
• Oxygen Barrier: EVOH layer blocks ≥99.9% O₂ ingress
• Moisture Barrier: Water vapor transmission rate (WVTR) ≤0.5 g/m²/day at 38°C, 90% RH • Light Barrier: Optional aluminum foil (9μm) for UV protection (add-on) |
| Safety & Compliance |
