Retort Bag
Retort Bags are heat-resistant, hermetic flexible pouches, crafted from durable multi-layer film and designed to withstand high-temperature retort sterilization (with airtight heat-sealed edges for long-term preservation).
These retort bags boast "high-temperature compatibility & extended shelf life" — a key advantage over standard pouches, as they maintain product safety and quality through sterilization processes. They’re the ideal choice for businesses packaging ready-to-eat or shelf-stable products, and we fully support small-batch customization for these bags.
Key Benefits
High-temperature sterilization compatibility is its focal feature.
It’s not only easy to process via retort sterilization but also enables long shelf life (without refrigeration) compared to non-heat-resistant packaging — boosting convenience for both businesses and consumers.
Features and Options (Add-Ons)
Common Structures (Materials)
For Retort Bags, we offer heat-stable material structures to endure sterilization:
- PET / AL / CPP (High heat resistance: blocks air/moisture, suitable for most retort products)
- PET / NY / CPP (Flexible heat resistance: ideal for irregular-shaped items)
- PET / EVOH / CPP (Enhanced barrier: for oxygen-sensitive retort foods)
- BOPA / AL / CPP (Durable heat resistance: for heavy-duty use)
These multi-layer structures withstand retort temperatures (typically 121°C+) while maintaining airtightness, ensuring product safety and freshness. All material options are available for small-batch customization, so you can pick the perfect structure for your products.
Applications (Industries)
- Foods (ready-to-eat meals, soups, sauces, canned alternatives)
- Pet Foods (shelf-stable wet pet food, nutritional pet supplements)
- Pharmaceuticals (heat-sterilized liquid medications, medical nutrition)
- Industrial & Other packaging (sterilized chemical reagents, emergency supplies)
