Packaging of food

Packaging has become an integral part of the processing, preservation, marketing and even the cooking of foods.

Initially, packages served simply to contain products and to protect them from outside contamination. However, there has been tremendous growth in the development and design of new packages to fit specific needs.

While there has been adaptation of many of the traditional packaging materials, e.g paper, glass, and metals (tin, steel, and aluminium), much of the growth has been due to development of plastic or flexible packaging materials.

Packaging materials may be composed of single component (usually one chemical substance polymeric, building block form) or they may be composed of multiple components, consisting of the variety of materials, usually laminated in layers, offering many advantages not provided by single components.
