ABSTRACT:
A method and product relating to a thermal insulation package wherein a container made from laminated sheet material including an inner layer of kraft paper, an outer layer of aluminum foil and an intermediate layer of fiberglass webbing is provided; the three layers are adhesively secured together and the inner surface of the kraft paper is coated with a heat-activated adhesive; the sheet material is formed into a tubular section by overlapping opposite edges of the sheet material and heat sealing the edges together; the tubular section thus formed is subsequently cut into tubular sections of smaller length, the bottoms of each of the smaller sections are then heat sealed, the containers thus formed are filled with polystyrene pellets and a hydrate compound is added; the open end of each of the containers is then closed and heat-sealed to form the completed package.
