ABSTRACT:
A laminated protective packaging material particularly for use in making heat sealable envelopes comprises an outer paper substrate having a continuous, aqueous based heat sensitizable coating applied to one surface thereof. The outer paper substrate may consist of conventional coated or uncoated paper, bleached or unbleached kraft paper or any other similar material. The heat sensitizable coating may consist of an alkali-soluble ethylene-acrylic acid copolymer resin or other heat sensitizable ionic polymer resin with or without the addition of filler materials for increasing the viscosity of the coating and/or for improving the heat sealing characteristics of the coating. The heat sensitizable coating is particularly characterized by its ability to be heat sealed to itself and laminated to a foamed polymeric material having a cellular structure such as polyethylene foam.
