Enclosing a product in a specially designed container for safe delivery to the end user is packaging. Packaging contains, protects and preserves the product. Packaging of product also informs about the product, sells the product and provides convenience to the consumer. Dairy products differ in their chemical composition and physical and rheological properties. Therefore they require packaging material with different characteristics. Most of the dairy products are highly perishable and are spoiled by external agents like moisture, light, gases, odours, biological agents, mechanical hazards, etc. The packaging material should possess barrier properties against all these agents to serve the purpose of packaging. In addition, the form of packaging should appeal and provide convenience of carrying, opening, re-closing etc., to the consumer besides meeting the protection requirements.
