Product Attributes
This product is a Microwave Auto-Venting Retort pouch, using PET/PA/CPP three-layer composite structure, designed specifically for microwave ready-to-eat foods, integrating auto pressure relief, high temperature Retort, and high barrier protection.
Product Features
The outer PET layer ensures rigidity and fine printing; the middle PA layer provides anti-puncture and toughness, handling external impact during frozen storage and transportation; the inner CPP layer withstands 121°C high temperature Retort processing, with firm and reliable heat-sealing.
The core highlight is the precisely positioned auto-venting design - a safe venting channel is formed during pouch making; when internal pressure rises during microwave heating, the channel automatically opens for pressure relief, and closes after heating is complete, effectively preventing bulging, bursting, and splashing.
Functional Characteristics
PET and PA work synergistically to achieve high rigidity display and impact protection; the CPP layer ensures high temperature sealing; the auto-venting structure intelligently senses internal pressure, without needing to open or puncture the pouch throughout, solving the bulging and bursting hazards of traditional microwave heating.
Product Applications
Suitable for packaging of microwave ready-to-eat foods such as prepared dishes, cooked food, dish packs, frozen rice/noodle products, and instant soup.
