MULTI-LAYER RESIN/PAPER LAMINATE STRUCTURE CONTAINING AT LEAST A POLYMER/NANOCLAY COMPOSITE LAYER AND PACKAGING MATERIALS MADE THEREOF

摘要

A laminate structure for both packaging and non-packaging applications, including a multilayer polymer layer laminate containing at least one polymer/nanoclay composite layer coated or applied to paper or paperboard. The laminated structure may contain optionally a tie-layer or other layers, as needed for the application. The polymer/nanoclay composite layer is preferably a blend of a polymer resin, such as nylon 6, and a finely dispersed nanoclay such as smectite, with a dispersion on the nanometer scale. The polymer/nanoclay composite layer provides improved oxygen and moisture barrier characteristics to a package, prepared from such a laminated structure, as well as improved rigidity and heat resistance, thereby providing longer shelf life and excellent flavor retention to the stored contents as well as improved dimensional stability to the cartons, package or containers. The method of making such laminated structures and the cartons, package or containers made therefrom are also covered.
