Retort pouches are the new age flexible packaging which has the potential to cater to all your packaging needs.
This packaging has changed the way we bundle our food products. It has the sturdiness of metal cans and protects the nutrient value of the food because of its four layers as shown in the image below.
The materials that go into the packaging of retort pouches are FDA approved and undergo sterilization process which increases the durability of the packaging.
The first layer is propylene which acts as a heat seal surface and provides strength and flexibility. The next layer which is the nylon layer protects from abrasion. The aluminium layer not only protects from lights, gases and odour but also extends the products shelf life. The final polyester layer provides excellent strength and is very easy to print on.
The idea for retort pouches was promoted by the US army in 1950 and the research continued through 1960 and it was finally invented by United States Army Natick R&D Command, Reynolds Metals Company and Continental Flexible Packaging and were first introduced in Italy. These companies received the Food Technology Industrial Achievement Award for its invention in 1978.
Retort pouches and its types like stand up pouches, spout pouches and zip lock pouches have revolutionised the packaging industry. All these types of pouches along with other packaging products like corrugated boxes, adhesive tapes, cling films, disposable glasses; tissue paper etc. can be purchased easily on e-commerce websites like Bizongo which is a one stop shop for all your packaging requirements.
These pouches faced a stagnation period in the beginning due to the reluctance of the people to accept them but through the years have realized that using retort pouches for packaging has a number of advantages.
For example, despite of the four layers retort pouches are very light weighted and can be transported and stored very easily.
Retort pouches can stand upright on the shelves and this helps in maintaining the food composition inside. They utilise just 5% of the packaging material and at the same time improve the food texture, flavour and aroma. Also the energy that goes into the production of these pouches is much less than the packages made from metals, paper or glass.
These pouches are flat and hence take up very less space on the shelf as well as in the shopping bags. Due to the sturdy packaging, these pouches are protected during transportation and the quality of being light in weight proves to be very cost effective during transit.
They can stand temperature variations up to 250 degrees and are leakage proof. Also, these pouches are made with high quality materials and are environment friendly.
They are used to package different types of food like organic, frozen, pet, soup, fresh food etc.
Retort pouches have gained a lot of popularity and have been adopted by many companies such as Knorr and Nestle for the packaging of their products and today can be seen on the shelves of many retail stores.
Retort pouches have become a convenient way to package pre-cooked and processed food and are proving to be more effective than the conventional packaging methods and are definitely the future of food packaging.4
