Liquid packaging Heat resistance High barrier Eight-side-seal spout pouches: Innovative packaging design to enhance user experience

Problem Spotlight: The 3 Fatal Flaws of Standard Liquid Packaging

“Why does soy milk turn rancid despite refrigeration? Why do pouches leak during shipping?”

Data insights expose critical gaps:

❶ Oxygen Infiltration: Ordinary stand-up pouches with OTR ≥2.0 cm³/m²·24h accelerate lipid oxidation by 32% (FDA Study).

❷ Seam Failures: 68% of transport damage originates from weak side seals (ISTA 3E Simulated Test).

❸ Batch Contamination: Poor heat resistance causes 7% pouch delamination during retort processing.
