Premium popcorn brand Propercorn will be expanding its range with sharing bags next year.

The brand, which is currently available in 20g packs, will be launching into 80g bags early in 2013 and is also looking to expand its range of flavours.

The news came as Propercorn revealed it had sold more than a million bags in its first year of trading, and was now available in some 1,000 outlets across the UK, including Waitrose and Harvey Nichols.
