Stretch Properties - Effects of Equipment and Process Variables, 2001 Polymers Laminations & Coatings Conference Proceedings
Michael V. Wainer--The Stretch Film Industry has grown at phenomenal rates over the past 6 - 8 years. During that time, Stretch Film has evolved from monolayer to three layer and now commonly a five or seven layer product. This film is processed on equipment that varies in size and width along with other technological differences. Equipment and process variables are key to achieving desired film properties on any Cast Stretch Film system. This paper will review the stretch film industry, outline the major stretch film properties, and show (by case study comparison of two similar cast systems) how equipment and process variables effect stretch film properties.
