The forms of packaging has gone through different phases and now with the development of modern science and technology, as well as the increasing awareness of health issues, there has been great improvement in the packaging processes. There are now many different forms of packaging with the use of different types of material for better and safer storage of products.
From the factories right up to the consumers, manufacturers face increasing challenges to ensure that their products remain in the best condition and quality beyond their expiry dates. The nature of the products and the packaging are both affected by the natural environment as they go through the process of handling, transportation and storage. That is the reason packaging plays a very important role in protecting manufacturers’ products. Time, money and attention are being spent in research to design and to develop high quality packaging to reduce the pollution or damage to the products from surrounding environment.
In the old days, natural materials such as leaves, wineskins, woven straw bags or baskets were used to contain and protect the products including food. Later wooden barrels, paper bags, glass, and potteries were also used until canning of products were introduced as airtight containers for the preservation of food. The labelling of the packages or cans were in the form of written or printed labels on separate materials individually pasted on the packages or cans. These were the rigid forms of packages and they take up a lot of storage space.
In our modern days with the introduction of high quality flexible packaging, we now have non-rigid forms of packaging in the forms of bags and pouches. This type of flexible packaging is made from the lamination of flexible materials such as plastic, metal foils, and others to form a multilayer structure. These type of packaging enables the edible products to be handled and packed by aseptic processing. Compared to the traditional industrial canning methods of packing and storing edible products, this sterile packaging is a better alternative to protect and ensure the products stay fresh and safe for consumption.
Flexible packages such as bags and pouches are able to contain liquid to fully cooked meals for the convenience of our modern consumers. These fully cooked meals are ready for consumption or if you wish, they can be heat-treated in their packages or you can pour them out into a container to be heated over the store or in a microwave oven. According to the printed instructions on the labels, some food can be heated by submerging the packaged food in hot water and once heated, the food is ready to be poured out from the package for consumption.
Flexible packaging is popular among producers of edible products such as dairy products, snacks, pet food, natural food, medicines, as well as non-edible products such as farming or gardening products and many others. Flexible packaging comes in the form of bags or pouches and these are designed and constructed with zipper, 3-side seal, and stand-up pouch with bottom and side gussets.
There is no need for the printing of separate labels as the labels are printed directly on the packages itself using the digital printing and laminating processes. In this way, the use of digital printing helps save cost and time, plus the graphic quality is better and more attractive.
