Abstract

A pencil barrel is prepared by extruding, shaping, and cooling, under controlled conditions, a foamable, thermoplastic resin-based composition. The combination of the particular extrudable composition and the means of shaping and cooling the tubular extrudate obtained therefrom are readily useful as barrels, i.e. sheaths, for sharpenable pencils, particularly in the cosmetic industry. The resultant pencil barrels are characterized by their sharpenability, uniform satin-matte smoothness, outstanding printability, and their prolonged resistance to atmospheric conditions. The method for making said pencil barrels is also disclosed.
