Application Of Retort Pouch In The Neutral Beverage

Jan 09, 2019

The retort pouch is also called a soft can bag. It is a soft packaging container made of a multi-layer composite film made of polyester, aluminum foil, polyolefin, and other materials.

With the improvement of the technical level and the emergence of new technologies, the high-temperature cooking bags composed of three-layer and four-layer composites have been widely used.

Different retort pouch materials should be used for different beverage types. Mainly based on the shelf life, sterilization temperature, price and other factors of the package content.

Neutral beverages have an HP value of 4.5 or higher and require a high sterilization temperature and good storage conditions. At present, the sterilization temperature of neutral beverages is mostly above 120 °C, which can basically kill pathogenic bacteria in beverages. Long-term storage can be achieved if it is not invaded by oxygen and microorganisms during storage. Suitable bags for neutral beverages are polyester/aluminum foil/polypropylene, polyester/aluminum foil/nylon/polypropylene, nylon/aluminum foil/polypropylene, polyester/aluminum foil/polyester/polypropylene.

Lanker's retort pouch can withstand temperatures from 120 ° C to 135 ° C and has the ability to withstand the rigors of the cooking process. Lanker's retort pouch has a small thickness, fast heat transfer and short sterilization time. It can keep the original color, aroma, taste, and nutrients in the food; no preservatives, fungicides and other additives are needed; there is no function of metal cans, but there is no special taste of metal cans; commercial circulation under normal temperature; can be directly heated, easy to eat, lightweight, easy to carry; good packaging material printing; good oil resistance; high-temperature cooking bag containing aluminum foil has anti-oxidation and anti-oxidation Ultraviolet properties for long-term storage.
