Extrusion Coating Technology: Product Design, Processing & Troubleshooting

OVERVIEW
Extrusion coating and laminating represent a major portion of the food, consumer and industrial packaging products made in this country. It is a multibillion-dollar industry on the leading edge of extrusion coating phototechnology, producing products such as multi-layer flexible packaging, milk cartons, drinking cups, aseptic packaging, release papers, graphics papers and much more. Substrates such as lightweight paper, heavyweight paperboard, film, foil, and woven and non-woven fabrics are combined with a variety of polymers to produce a nearly endless list of products.

This course consists of two days of classroom work centering around the equipment and process of producing various extrusion coated and laminated structures, and around equipment and raw materials and processing. Emphasis is placed on the research and development process to produce various common product structures, as well as processing conditions, process setup and troubleshooting to make those products. The discussion will include an in-depth description and potential uses and limitations of extrusion coating including foam extrusion, film lamination, anti-oxidants flame retardents, foil laminations and more.

Although there is no prerequisite for this course, knowledge of extrusion coating processing and some background in plastic, paper and foil raw materials would be helpful.
