Slovenian Sovereign Holding (SDH) said it would once again contact potential investors to see whether they were interested in buying at least parts of the loss-making company, which employs about 220 people.
In its October tender, SDH had said the buyer would be expected to invest about 2.2 million euros ($2.3 million) in the company in exchange for a stake of over 50 percent.
Polzela is one of about 30 companies the government wants to fully or partially sell off as part of economic reforms.
