A composite stock material in sheet form for use in making various types of packaging for compact discs has an outer layer of paperboard material (12) thermally fused to an inner layer of bonded nonwoven fibers (16) through an intermediary layer (14) of thermoplastic material. The preferred composite is solid bleached sulfate boardstock of 18 pt. caliper, 100 % low denier, staple length polypropylene thermalbond, and an intermediary LDPE film of a weight of 10 lbs/ream. The composite sheet is a single stock material that can be manufactured into envelopes, cartons, sleeves, wallets, or any other type of desired packaging for compact discs.
