The retort pouch for packaging cooked chestnut was designed including the process of materials selection,thickness deciding,and theoretical shelf-life calculation.
The optimum materials and thickness was obtained through the theoretical analyses and calculations as follows: transparent materials PET12/PVDC15/CPP50,no-transparent materials PET12/Al9/CPP50.The designed shelf-life of retort pouch in moisture-proof packaging was over 4 years through theoretical calculation by the allowable weight for water of cooked chestnut,the permeable coefficient,and the designed thickness of materials.
This paper deals with how to make retort pouch fruits by adopting techniques of high acid(PH<3.7)and low sugar (12~16%) with liquid protection condition, vacuum packaging (pressure 0.021~0.034MPa) ,minimum thermal process and fast cooling under normal pressure etc.
To explore the structure of some key parts, the working principles and the characteristics of model TT-8C retort pouch auto filling and sealing machine and to reform & design some parts of the machine to make the producing machines for retort pouch products that can realize auto filling and sealing.
Now some of these products have become so popular that they are mass-produced and packed in retort pouch packing and exported.
This paper reviews the development and structure characteristics of retort pouch and present state and prospect of domestic and foreign market.The performances,technical standards and testing methods of laminated films are also studied.The adhesives selection for lamination and the related process and equipment are also discussed.
