Multilayer Coextrusion Coating for Flexible Packaging, 1990 Polymers, Laminations & Coatings Conference Proceedings

The aim of this paper is to introduce an optimized multilayer coextruded coating with high barrier, heat resistance, heat seal, and adhesion on the paper as well as between each plastic layer. The price of this multilayer construction should be low enough to compete, for instance, in the flexible packaging field. A pilot coextrusion coating line was used to produce ACBCA and CBCAA constructions on the MF paper of 70 g/m2. Several heat seal, barrier, and adhesion polymers were tested. Taking into account the runnability, the price, and the multifunctional behavior, the optimized CBCAA structure is as follows:

/ Bynel CXA/EVOH/Bynel CXA/PP graft copolym./PP graft copolym./
