Below are answers to common questions about our custom retort bags and rolls. For detailed specifications or project support, please feel free to contact our team.
The MOQ depends on the printing method. For digital printing, the MOQ is 500 pcs. For gravure printing, the MOQ is 10,000 pcs.
The production time is usually 7–15 working days after the final artwork is confirmed. The exact lead time depends on order quantity, pouch structure, and customization requirements.
Yes. Our retort pouches are made with food-grade materials suitable for high-temperature sterilization and direct food contact.
Some retort pouches can be designed with recyclable material structures, such as mono-material or recyclable laminated options. The final recyclability depends on the pouch structure and local recycling facilities.
Food packed in retort pouches can usually last 6–24 months at room temperature, depending on the product type, pouch structure, sterilization process, storage conditions, and shelf-life testing results.
Some retort pouches can be microwaved, but the material structure must be suitable for microwave heating.
Aluminum foil retort pouches are not microwave-safe, while non-foil structures such as ALOxPET/NY/RCPP or other microwave-compatible materials can be used for microwavable retort pouch packaging.
Retort pouches are designed for high-temperature sterilization, typically 121°C–135°C, and are suitable for shelf-stable foods that can be stored at room temperature after retorting. They use heat-resistant laminated structures such as PET/AL/RCPP, PET/NY/RCPP, or PET/NY/AL/RCPP, offering strong sealing, barrier protection, and long shelf life.
Boil-in bags are mainly used for reheating or cooking food in hot water, usually around 80°C–100°C. They are not necessarily suitable for high-pressure retort sterilization and often require refrigerated or frozen storage, depending on the product.
Vacuum bags are used to remove air from the package to slow oxidation and extend freshness. They are commonly used for meat, seafood, cheese, and sous-vide products. However, standard vacuum bags are not designed for retort sterilization unless they are made with retort-grade materials.
