Pronit

Initially center labels deisgn was similar to those of Polskie Nagrania Muza and those two labels had the same catalog numbering system and common numbering sequence. On both lebels "Polskie Nagrania Warszawe" was printed.
In the begining of the 80's "Pronit" Label became a standalone label with its own numbering system, center labels design also changed.
Production of records with "Pronit" label ceased in 1991.

Plastic Materials Factory "Pronit" in Pionki was reactivated in December 2010 as the ZPS sp. z o.o.
