There are various challenges that face the manufacturers and suppliers of food products in the country and abroad. These challenges can be grouped into two broad categories - social and economic. The challenges faced by the industry can vary according to locality. In the developed countries, where the economy is generally developed, the scale of production required is relatively low. The challenges faced by the industry can also vary as per the type of product - for example, perishable goods like fish and milk need a different type of packaging than that used for vegetables or chicken.
As far as the quality of frozen food packaging is concerned, the overall picture is not good. Many leading brands in the country and abroad use inferior quality materials like PVC to manufacture their products. As a result, consumers suffer because they find the end product to be of low quality. Some of the commonly used components in the manufacture of these plastic packaging include PVC joints, double-sided tapes, high-quality clamps, UV inhibitors, resin, high temperature adhesives, etc.
High quality stand-up bags are often considered the ideal option for food vendors because the products are more hygienic and free from any kind of leakage. However, recent studies have shown that plastic seals account for more than 70% of the total leakage in food. This means that the manufacturers of products like canned fish and sardines are often faced with an unexpected leakage while carrying out the sealing process.
While the conventional PVC seals remain to be the preferred choice for food manufacturers, the high cost involved in them makes them unaffordable for many small food retail stores. Moreover, the smaller stores cannot afford the larger variety of products that are available in canned form in their inventory. As a solution to this problem, suppliers have started using polyethylene and other synthetic fabrics like vinyl and polypropylene for the purpose of frozen food packaging. Though both these materials are more expensive than PVC, they offer a superior sealing ability and superior durability.
The latest addition to the frozen food packaging material is the so-called temperature sensitive seal pouches. These devices are available in various sizes and can be used by any store which requires an effective temperature-resistant packing. The device has a built-in sensor and temperature probe that activate only at the predetermined temperature. This helps avoid the occurrence of uneven heating within the can and ensures uniform sealing of the can through the entire cycle of packaging.
Apart from food products, manufacturers of medical supplies and pharmaceuticals also prefer the quality of sealed tin cans over other sealing methods. Tin cans help protect the chemical components of medicines and the equipments that are used to manufacture them. Manufacturers of medical devices have been using these tin cans for years due to their effectiveness in securing the right temperature and ensuring leak-free sealing. Hence, the latest additions to the frozen food packaging material are tin cans that not only provide cost-effective sealing but also help maintain the quality and efficiency of manufacturing equipments.
