Abstract

Abstract An antistatic phonograph record envelope for storing records in a cardboard jacket is made from extruded plastic film having a thickness between about 1 and 6 mils with an antistatic agent extruded within the film. Layers of the plastic film have one or more seams providing a closed end and sides while an open end of the envelope has an elongated slit through which the record is inserted into the envelope for storage and pulled out of the envelope for use. The antistatic agent in the plastic film layers prevents the buildup of static electricity on the record as it is inserted into and pulled out of the envelope and also dissipates any accumulated static electricity on the record during storage within the envelope. At the open end, the plastic layers preferably have cooperable projections that are snapped into engagement with each other to provide a seal for the envelope. A flap at the open end of the envelope projects out of a square cardboard record jacket with the envelope and a stored record inserted therein so as to facilitate removal of the envelope from the jacket.
