Retort Pouch is a semi-rigid, flexible and leak-proof packaging solution made from heat resistant laminated plastic capable of withstanding a high temperature of up to 250 degrees. This heat resistant characteristics of the pouch allow the sterile packaging of a wide variety of food products, making it the ideal go-to packaging option for convenient, processed and pre-packaged food.
Retort Pouch properties
A standard Retort Pouch is made of 4 layers, is FDA approved and has undergone sterilisation to increase the durability of the packaging.
- Propylene. Acts as a heat seal surface and provides strength and flexibility.
- Nylon. The layer which gives the pouch its abrasion-resistant feature.
- Aluminium Foil. Capable of extending the shelf life of product and functions as a protective barrier to light, gases, microorganisms and odours. The stiffness of the aluminium foil enables the tear notch feature to be incorporated to the pouch.
- Polyester. Provides high-temperature resistant, strength and ability to print graphic on.
Benefits of using retort pouches
- The multiple layers of the Retort Pouch help to reduce heat exposure which preserves and improves the colour, aroma, taste and shape of food-product as well as minimising nutritional lost.
- The flexible nature and the ability to stand upright not only helps to maintain the composition of good, but it also takes up little storage space on the shelf. This, in turn, allows ease of distribution as more products can be transported at a time, saving on transportation cost as well.
- The Retort Pouch enables the “tear notch” feature to be incorporated to the pouch to allow easy opening of the package.
