Câu hỏi thường gặp
What material structure is commonly used for retort pouches?
Common retort pouch structures may include PET/AL/RCPP, PA/AL/RCPP or PET/PA/RCPP, depending on food type, sterilization condition and shelf-life requirement. The structure must be confirmed before production.
Can all pouches withstand 121°C sterilization?
No. Retort performance depends on material structure, sealing layer, pouch thickness, food content and sterilization time. The structure must be confirmed before production. Standard pouches should not be used for retort processing.
What information is needed before retort pouch quotation?
Buyers should provide pouch size, material requirement, thickness, filling weight, food type, sterilization temperature and time, quantity and artwork file. This helps verify whether the proposed structure can meet retort conditions.
Why is sealing strength important for retort pouches?
Retort pouches must keep stable sealing during high-temperature sterilization and subsequent handling. Poor sealing can increase leakage or delamination risk during the retort process.
Can retort pouch samples be tested before bulk order?
Yes. Buyers are encouraged to test sample pouches under their actual filling and sterilization conditions before confirming bulk production. This helps verify that the structure performs correctly under real processing conditions.
