Food Composite Film Soft Packaging Bags
In 2023, a large food processing factory in Shandong exported a batch of high-temperature retort meat packaging bags, which experienced bag bulging and oil seepage during transportation. After investigation, it was found that part of the bag bodies were not sealed properly and had micro-leaks. The factory subsequently introduced leak detection equipment (negative pressure method + mass flow method) for sampling inspections, setting the standard as "negative pressure -30kPa, holding pressure for 60 seconds, leakage ≤ 5 sccm". The subsequent factory qualification rate significantly improved, successfully restoring stable export deliveries.
