Abstract
In western Europe alone over 6 million tonnes of polymer are used each year in the production of film. The films market is also currently expanding at about 10% per annum. This is attributable to some unique properties of films particularly attractive to the food packaging business, by far their largest market sector. Films can be passive and offer aesthetics, but they can be active and offer protection of contents, perhaps against oxygen or water vapour, thereby extending shelf-life and reducing food wastage. This makes polymer films cost-effective. The lower energy requirements for processing of polymers relative to say glass and metals, together with major technological advances in segregation and reclaim, means that plastic films can be considered as a material asset in a progressively more environmentally sensitive world.
