| Abstract |
Packaging materials play an important role in preserving food materials and consumer acceptance. To achieve better and longer preservation and to get consumer appeal many natural and synthetic packaging materials are widely used. Often these materials are used individually and in combination to give desired properties like moisture resistance and barrier properties against permeation of gases, oil, microbes, light etc. To achieve these properties many a product like synthesis polymers, natural films and boards, metal foils/sheets are used individually as well as multilayer lamination using a variety of adhesives. |
