Net sales for the first six months of 2020 increased $86.5 million, or 4.1 percent, to $2.21 billion as compared to $2.12 billion for the first six months of 2019. This increase was primarily a result of higher volumes in each of the businesses, including the impact from acquisitions, and a more favorable mix of products sold in the closures business, partially offset by the pass through of lower raw material costs across all businesses, a less favorable mix of products sold in the metal and plastic container businesses and the impact of unfavorable foreign currency translation.
