In 2012, unit volume of alcoholic drinks packaging grew positively, mainly backed by volume sales growth of major alcoholic drinks products such as beer and Soju. Soju is a low-priced local spirit that is classified under "other spirits". Beer and other spirits make up the major share of alcoholic drinks packaging volume, because these product categories hold a dominant share of total alcoholic drinks sales volume in South Korea. In 2012, beer and other spirits accounted for 86% of total unit volume of alcoholic drinks packaging. As the sales volume of these large product categories continued to rise, unit volume of alcoholic drinks packaging grew positively in 2011 and 2012 in all major pack types, including glass, metal and rigid plastic.
