The Wigan-based company handled more than 4,800 tonnes of packaging in 2005/06 but failed to register with a compliance scheme to meet its obligations to pay for packaging waste recycling.
Environment Agency investigations revealed it should have been registered since 1998.
Appearing before Wigan and Leigh magistrates on 26 April, the company pleaded guilty to 15 offences under the Producer Responsibility Obligations (Packaging Waste) Regulations 1997. It was fined £50,000 with £2,278 costs. The company said its non-compliance had been an oversight and it now employed a consultant to ensure this did not happen again.
