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.
