In broad terms, packaging refers to the technology of enclosing a product for the purpose of storage, distribution, sale, and use. Flexible packaging is a non-rigid method of packaging, and flexible packaging products are made from flexible materials such as plastic, aluminum, and paper. These materials undergo a detailed conversion process such as printing, lamination, coating, and extrusion to develop different types of flexible packaging products, such as plastic bags and pouches, lidding films, foil bags, and sachets. Packaging these days is not only used to protect a product from spoilage, but it has also become important in improving the overall aesthetic appeal of the product, providing essential information about the product, maintaining the freshness of food and beverages, and providing convenience for consumers in terms of handling/carrying the product.
