Abstract
A receptacle (10), such as an attache case or brief case, has a cover panel (22), back panel (24), front panel (26), top panel (30), bottom panel (32) opposing tabs (34) and opposing side panels (36). The case is made from a unitary sheet of expanded polyethylene. The expanded polyethylene sheet material is produced by encapsulating a thermoplastic blowing agent (azodicarbonamide) within an ethylene vinyl acetate carrier resin to form a pelletized compound which is combined with high-density polyethylene resin and extruded. The melt temperature of the pelletized blowing agent is lower than that of the polyethylene resin, and controls the expansion of the polyethylene resin.
