98°C vs 118°C Seal Initiation · 2.4x Higher Hot-Tack · Zero Gusset Leakers · MOQ FROM 500 PCS ($0 DIGITAL PLATE)
Metallocene Plastomer (mLLDPE) vs. Conventional Ziegler-Natta LLDPE: Hot-Tack & Drop Comparison
Why FlexPouchMFG™ standardizes on virgin metallocene mLLDPE for all food and liquid pouches: lower seal initiation temperature (98°C), superior hot-tack under heavy fill drops, and zero off-taste.
"When qualifying Metallocene Plastomer (mLLDPE) vs. Conventional Ziegler-Natta LLDPE: Hot-Tack & Drop Comparison (CMP-MPE-15) for High-Speed Vertical Filling, Liquid Spout Bags & Heavy 1kg–15kg Pouches, 90% of field failures occur at the heat-seal interface due to product contamination or differential web shrinkage. By pairing our Metallocene mLLDPE (SIT 98°C) vs Standard C4-LLDPE (SIT 118°C) 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."
