Method of producing a data disk holder with adhesive seal strip

Abstract

A method of producing an adhesively closable data disk holder having of a pair of heat-sealable plastic panels fused together to form an interior pocket with an opening thereto, wherein an additional adhesive layer is fused to the inner surface of one of the holder panels adjacent the opening thereof to facilitate adhesive closure of the opening without the use of an overlying flap. The adhesive layer is constructed of a thin panel of compatibly heat-sealable plastic material, one surface of which carries a pressure sensitive adhesive over which an adhesive release strip is disposed. The adhesive layer is disposed between the outer holder panels so that the adhesive release strip insulates against fusion to its adjacent panel, as the opposing non-adhesive surface of the adhesive layer is heat-sealed to its adjacent holder panel. The process results in a data disk holder having a substantially uniform thickness throughout which is particularly beneficial when used in a bindery process.
