In this revised and updated edition the section on vacuum and gas packaging, for example, has been expanded to include work on controlled/modified atmosphere packaging ,while the chapter on thermoforming has also been expanded with extra sections on control of wall thickness, automatic operation and solid phase pressure forming. The chapter on health safety has been rewritten to include updated information on the theory and legislative aspects plus additional information on microwave cooking, irradiation and modified atmosphere packaging. The chapter on organolepsis has also been rewritten to incorporate details on the newer techniques involving computers. Finally, a new section has been appended on additives for plastics films in order to give a technological background to complement the health safety factors of additives.The book is intended to serve as a useful reference work for user industries and a text for students in the fields of plastics and packaging)
