ABSTRACT OF THE DISCLOSURE Hermetically sealed articles are provided which enclose a porous mass of material of relatively low heat conductivity and a charge of a gas having a coefficient of thermal conductivity lower than that of air and thoroughly permeating the porous mass of material or such sealed pouches may enclose only the porous mass of material evacuated down to about 10 mm. Hg. The pouches are useful as thermal, insulation materials and are constructed of confronting sheets of multi-ply laminate material sealed along free edge portions thereof and comprising (1) a multi-layer film including a core layer of ethylene vinyl alcohol copolymer adhered on each side to nylon, each nylon layer being adhered to a layer of chemically modified polyolefin; (2) optionally, a low density polyethylene layer; (3) a layer of primer material suitable to effect adhesion between said modified polyolefin layer or polyethylene layer and the outer layer of oriented polypropylene or other material suitable for conveying toughness, flex crack resistance and moisture barrier properties to such multi-ply laminar construction. The articles are useful as thermal insulation materials.
