Multilayered plastic film study published

A new book, ‘Extrusion Coating, Lamination and Coextrusion: The complete process manual’, published by Plastics Information Direct explores and explains the three key processes used to manufacture multilayered plastic films: extrusion coating, lamination and coextrusion. 

It is said to be a complete process manual for industry professionals in the development, production or specification of films. It will enable readers to optimize product performance and evaluate the most cost-effective options, with useful information on the key polymers and substrates used.

Multilayer film structures provide properties and performance required for applications such as food packaging and medical products which could not be achieved by a single material, while also exploiting cheap and easily processed polymers – primarily polyethylene. All three processes described can be used in their manufacture, and in combination provide further options and benefits.

Written by Bert Gregory, the practical process manual contains useful advice describing the effects of machine design, process variables and materials selection. Gregory has 35 years’ experience in the plastics industry. This experience, integrated with experimental data and computer modeling, allowed him to arrive at conclusions and recommendations based on quantative data and achieve the manual’s ‘cause and effect guiding principle’.
