Extrusion Coating: A Process Manual

by B. H. Gregory

220 pages; quality trade paperback (softcover); illustrated; catalogue #04-1879; ISBN 1-4120-4072-8; US$102.47, C$102.47, EUR70.00, £52.91

Some of the topics this manual covers include chill roll cooling efficiency (effect of temperature and size); how to optimize screw and die designs and increase line speed, and much more.

About the Book

This comprehensive study of extrusion coating technology describes the process in detail, combining experimental data with computer modeling and the author's 30 years of experience. This methodology provides insight, clarity and assistance in problem solving and process optimization.

Everything you wanted to know about:

• Screw and die design for mono and coextrusion.
• Chill roll design and winders.
• Maximizing adhesion at high line speeds:- time in air gap and melt relaxation.
• Adhesion promotion:- corona, flame, ozone treatment and chemical primers.
• Feedblock and dual manifold coextrusion compared.
• Coextrusion:- control layer arrangement and eliminate interfacial instabilities.
• Optimize melt stability and minimize neck-in in air gap.
• Material selection:- polyethylenes, copolymers, ionomers, metallocenes, polypropylene etc.
• Substrates: pulp and paper, aluminium foil, plastic films etc.
• Applications for extrusion coatings and laminates.
• Minimize odor and off-taste and the scalping phenomenon in food packaging.
• Trouble shooting and many more insights.

Target Audience: Engineers, marketers, technicians and students involved with the extrusion coating process.
