The most popular packaging solution for preserving food items is active packaging, described as enclosing food to protect it against tampering or contamination from physical, chemical, and biological sources.
Every year, the grocery industry generates over $680 billion in sales. Grocery stores housed around 7,000 different products in the 1990s; now, they carry up to 50,000. Because of this dramatic increase in the number of products on the shelves, there exists tough competition for brands. Customers can choose from a wide range of cheese products, many different staple food brands, dozens of soft drink brands, and so on.
Intelligent brands understand that moving food packaging design and package graphics are necessary to grab customers' attention. Food packaging assists consumers in identifying the product (this is also known as package graphics). It frequently includes nutrition facts labels. Similarly, food packaging keeps the products safe from harmful environmental effects and extends their shelf life, the period during which the food item is safe to consume.
Food packaging also improves the convenience of eating and drinking. Tetrahedron-shaped plastic-coated paper carton milk packaging is much easier to store and pour than any other milk packaging.
Finally, food packaging is to help promote the product and persuade customers to buy it.
The growing popularity of online grocery shopping has compelled many brands to reconsider their packaging designs to make the most of a small screen.

But, many are still unaware of where reductions may be made successfully. The information in Food Packaging and Shelf Life: A Practical Guide helps package designers specify the ideal quantity of protective packaging to preserve food quality and extend shelf life.
