The primary functions of packaging are to protect the product, communicate important information about the product, optimise shelf life and, of course, packaging has a role in tempting the consumer.
The primary packaging determines the preservation of the products and consequently their shelf life. To extend the shelf-life of products, many aspects are important: the cleanliness of the packaging environment, the barrier properties of the packaging materials used, the seal quality and thus the leak tightness of the packaging. Some products need to be packed under a protective atmosphere to extend their shelf life. This, in practice, means gas flushing of the packaging to reduce the oxygen percentage in the packaging.
Consumer convenience and recyclability of the packaging are important aspects in the development a successful packaging concept.
