Abstract
Abstract A perforated package of a composite integral sheet material which includes a first layer of absorbent material, a second layer of printable material and an impermeable pigmented polymer layer interposed between the first and second layers. The composite material has a plurality of air pockets formed between at least one of the first or second layers and the polymer layer, by discontinuously bonding the first or second layers to the polymer material. The package has two parallel lines of perforation which allow access to the interior of the package and to the foodstuff contained therein. A method of using the perforated package of composite integral material.
