PROCESS OF MAKING LAMINATE STRUCTURES WITH HIGH BARRIER EXTRUSION COATING FOR FLEXIBLE PACKAGING AND LAMINATE STRUCTURE OBTAINED THEREFROM

摘要

A method and system of producing barrier laminate structure (12) for flexible packaging by co-extrusion coating / lamination of one or more substrates (16, 26), using one or more extrusion coating / lamination stations, comprising of one or more extruders (18, 30) at each of the stations, operating in isolation or in tandem yielding multilayered extrusion coating / lamination (ECL1, ECL2), comprises one or more intermediate barrier layer(s) and / or adhesive / tie / sealant layer(s) (20, 32) in the final laminate for enhanced oxygen, gas and moisture barrier as also aroma retention.
