Packaging & Printing
A retort package is a thin, lightweight, flexible laminated plastic package that is designed to store processed meals. It&#;s primarily made by retort packaging companies as an alternative for cans and glass jars, combining the lifetime of conventional food conservation techniques with the ease and advantages of a thin, somewhat pliable container.
Processed food in jars and cans has a number of advantages. It doesn&#;t need to be refrigerated and has a very long and consistent storage life. The issue is not with the preservation procedure, but rather with the expense and hassle of packing. Cans and glass jars are large and cumbersome.
They use a lot of storage space, which raises your shipping and storage expenses. Lightweight retort packaging improves packing efficiency. As a result, they provide significant cost reductions in transportation and shipment. These pouches demand less storage capacity before filling since they lay flat while empty, lowering warehousing expenses.
Filling the pouch and then subjecting the sealed packaging to ultra-high heat is how the retort sterilization method works. Heat is easily transmitted via the thin packaging, allowing sterilizing to happen up to 40% quicker than with jars and cans. Sterilization that is completed faster uses less energy and hence costs less. It also enhances the overall taste of the goods while increasing the firm&#;s manufacturing capability.
Retort pouches are available with a number of characteristics, allowing you to select packaging solutions that complement your products and directly address the demands of the consumers. Choose from a variety of design options, including as easy-open, resealable, and spout pouches. These pouches also have greater opportunity for front-facing marketing elements because of their long, somewhat flat fronts.
Consumers and merchants alike benefit from retort packaging. Easy-open and resealable options have a tear-open feature that makes them user-friendly, removing the requirement for can openers or adequate hand power to open jars. They also take up less room once they&#;ve been used.

A significant growth driver for the Retort Packaging Market is the expanding use of retort packaging in the food industry, as well as improved quality of life. In addition, rising demand for packaged food, pet food, and infant food, as well as a growth in the popularity of ready-to-cook and ready-to-eat items, has fueled market expansion. As a result, retort packaging companies&#; businesses will grow tenfold in the future years.
Food packaging has become heart of modern food industry, which helps to store food and beverages in hygienic manner. Packaging is enclosure of products, items or packages in a wrapped pouch, bag, box, cup, tray, can, tube, bottle or other container contributing achieve functions such as containment, protection and /or preservation, communications and utility or performance. Packaging industry is one of the fastest growing industries in the world representing 11% growth in volume terms. Ready-to-eat food products have dominated packaged food Industry. Ready to eat foods (RTE) are convenience foods, enclosed in metal container or flexible pouches that only need to be cut open and heated before being served. RTE food includes wide range of ethnic food products viz. vegetarian / non-vegetarian, basic food / delectable desserts.
Changing lifestyle and nuclear families leads to exponential increase in the demand of ready to eat processed food. Retorting or In-bottle Sterilization is one of the major technique used for the thermal processing of convenient foods which are packed either in semi rigid flexible laminates or in metal or alloy cans. Packaging before heat treatment providing the advantage of both processing the food and packaging together, making filled product more commercially stable. This technique involves heating of food products prone to microbiological spoilage in hermetically sealed container to extend shelf life for commercialization of traditional or ethnic dishes, which are important due to their delicacy and are of high demand.
Processing techniques differ from product to product and from package to package, hence, retort designs and operating procedures vary. Traditionally, metal cans were used for retort processing however, over the years we have seen wide usage of pouches, plastic pots and trays, allowing more convenience, better product quality through reduced processing time, reduction in costs for food manufacturers and better surface to provide intended marketing information for consumers.
The materials of packaging must be inert, heat sealable, dimensionally stable and heat resistant (usually 115°C&#;125°C). They should have low oxygen and water-vapour permeability and be physically strong to resist penetration by the foodstuff contained and abuse during handling and storage.
Efficiency Determining Factor
A number of factors affects the Retort process, which includes
1. Type of container &#; Glass is not a good conductor of heat. Therefore, product in a glass jar takes more time to heat compared to equivalent size/shape metal can.
2. Size and shape of the container &#; A large container will take longer to heat than a small container, hence size of container matters.
3. Retort temperature &#; A higher retort temperate will result in more rapid heating but also may lead to more over processing of product near the package surface.
4. Agitation- Agitation of the containers will increase the heating rate by mixing the contents of the container, especially with viscous or semi-solid foods. End over end agitation is better than axial agitation.
5. Type of product &#; Different products conduct heat more or less easily and have different heat capacities. Some products are more viscous than others are which can have a particularly significant effect in agitating retorts.
6. Headspace &#; insufficient headspace can also affect the rate of heating, especially in an agitating retort.
Retort Packaging
1. Traditional Retort Cans:
The market for canned food products continues to grow which is driven by its high mechanical strength, the need for convenience, appealing recyclable properties of the cans, thermal stability, resistance to pressure and excellent barrier properties, increase in shelf life and food safety. Generally, tinplate (Consists low-carbon, mild steel sheet or strip, 0.50&#;0.15 mm thick, coated on both sides with a layer of tin) and aluminium are used for metal container and closure construction for food and drink products. Both are relatively low-cost materials and nontoxic, having adequate strength and are capable of being work hardened. Cans are used for safe preservation of low acidic food such as meat, seafood, poultry, dairy products etc. They have high mechanical strength but major disadvantage associated with them is that they take more time to transfer heat as compared to retort pouch.

1. Retort Pouch
Retort pouch is a flexible or semi-rigid package made from heat-resistant laminated metal - plastic, into which food products are placed, sealed and sterilized at temperatures up to 121°C. The resulting product is then sterile and shelf-stable. Retort pouches comes up in various styles such as three sided seal, four sided seal, stand up, stand up fitment and pre made form seal.
Retort pouches are used in several countries for a wide range of processed ready-to-serve shelf-stable products. Laminate films used for retort pouch manufacture vary depending upon their specific application.
Composition of Pouch
Mainly these flexible pouches are constructed with 4-ply laminate consisting of four layers:
1. Polyester: It offers high temperature resistance, toughness and Printability.
2. Nylon: It acts as puncture and Abrasion resistance
3. Aluminium: It acts as a complete barrier to light, Gases, Microbes, odours, extended shelf life, stiffness
4. Food Grade Polypropylene: it can be used as bonding and sealing layer, which gives strength and flexibility to the pouch.
There are also disadvantages associated with retort pouches. One disadvantage is the lack of strength of the material compared to metal cans. Retort pouches are much more prone to abrasions and punctures that ruin package integrity and potentially the product. More care and expense is needed when packaging retort pouches. Another disadvantage of retort pouches in the mode of retort generally used. Many continuous agitating retorts currently in use in industry were designed for compatibility with metal cans, and retort pouches cannot be processed in the same equipment. Therefore, retort pouches are frequently processed in less efficient still batch retorts resulting in higher operating costs. Batch operations are less efficient than continuous operations because of time needed for loading and unloading between batches
Quality checks should be carried out on pouches:
1. Visual assessment: to check there are no defects on the pouches both decorative and that may have an adverse effect on the process and shelf-life of the product.
2. Seal strength: to measure the strength of the seal for processing and storage.
3. Burst testing: to ensure the pack has adequate seal strength and integrity.
4. Oxygen and water transmission rates: to measure the barrier properties of the pouch.
5. Bond strength: to ensure the pouch has sufficient strength to prevent delamination of the layers.
6. Dye Test: The dye test can be used to identify the location of very minute holes.
7. Tensile Testing: Tensile tests are used as a quality assurance tool for assessing the inherent sealing qualities of flexible packaging films and are employed as an optional test.
Retort processing has evolved significantly since its incorporation into Department of Defence and NASA food system. While the technology still relies on aggressive application and penetration of heat throughout foods, recent advancement in process engineering coupled with evolution of packaging technology have allowed for overall improvement of the technology. Retort processing presents the advantage of increased shelf life with less loss of nutrients due to which it can be applied to process ready to meal, marinades, vegetable curry, soups and rice.
