Plastic Films, Technical and Packaging Applications.

Between 60 and 70 years ago a new material began to revolutionise the packaging of many products. The material was Cellophane, which began to be used and was marketed on a large scale. Suddenly, purchasers were able to see the merchandise quite clearly through a transparent pack which safely contained the product.

The use of such film continued to expand till the 1950s when a series of polymer films began to be commercialized. Such were the advantages of these newer films that, by the 1980s, they had replaced perhaps 90 percent of the Cellophane used in flexible packages. Indeed, such were the added properties of the new films and their laminates that a further growth has occurred is the use of flexible packs for packaging all sorts of products.

This book presents a comprehensive description of plastics films and their use in packaging. The first three chapters are devoted to the technology of plastics and plastics films before the authors turn their attention to applications. These are followed by chapters on machinery and descriptions of the types of film that are now used.

The fully descriptive chapter titles run: Polymers, Processes for making plastic films; Processes for modifying plastic films; Package functions and requirements; Packaging machinery; Packaging applications for plastic films; and Future trends and possibilities. These 7 chapters are followed by an appendix, glossary and index.
