An extrudable compounded polyvinyl chloride and a method for its preparation which comprises a free-flowing particulate mixture of polyvinyl chloride, selected plasticizer, silica pigment, selected heat stabilizer, selected chelator, lubricant, selected surfactant and selected slip-antiblock agent. The compounded polyvinyl chloride uniquely has, as an extruded film, anti-moisture fogging and oxygen transmissive properties suitable for packaging meat, yet can be used in high speed packaging machines.
