Changes have occurred recently in raw materials costs and supply of many packaging materials which have caused problems for packaging users. Those responsible for managing packaging in user organizations have faced considerable difficulties in seeking to predict future prices, price differentials or alternative packaging materials, as well as their availability, and in making investment decisions concering the packaging lines to be extended and those which must be replaced by alternatives. This new study sets out to investigate the process route for packaging materials and packs as part of an integrated system. For most materials it is possible to identify three stages from primary materials manufacture through intermediate manufacture, to conversion to final pack.
