When to Add a 15μm–25μm BOPA Nylon Core Layer to Your Barrier Pouch Laminate
While 3-layer PET/AL/PE works for lightweight dry snacks, liquids, bone-in foods, sharp coffee beans, and >1kg pouches require a biaxially oriented polyamide (BOPA) core to survive 1.5m drops.
"When qualifying When to Add a 15μm–25μm BOPA Nylon Core Layer to Your Barrier Pouch Laminate (CMP-NYL-09) for Heavy 1kg–15kg Dry Bags, Liquid Spout Pouches & 135°C Retort Pouches, 90% of field failures occur at the heat-seal interface due to product contamination or differential web shrinkage. By pairing our 4-Ply PET/AL/BOPA/PE vs 3-Ply PET/AL/PE structure with solventless polyurethane curing at 52°C and precision Totani ultrasonic gusset tamping, we guarantee ≥48 N/15mm seal strength and <0.5 mg/m² GC residual solvents on every shipment."
