Extrudable adhesives are used in coextrusion to bond two dissimilar materials together that otherwise would have poor adhesion to each other. The use of reactive systems, namely anhydride modified polyolefins, in coextruded multilayer applications is discussed. The reasons behind how extrudable adhesives work are given along with a review of the various adhesion mechanisms. The factors that affect adhesion during coextrusion are reviewed including processing and resin parameters. The information needed and the process of selecting an extrudable adhesive are covered. Guidelines for handling and processing extrudable adhesives are given.
