In 1990, RockTenn acquired Allforms Packaging Corp. of Long Island, New York, and Box Innards Inc. of Orange, California. The next year it purchased the former Specialty Paperboard Inc. mill in Sheldon Springs, Vermont, and Ellis Paperboard Products Inc. of Scarborough, Maine, a manufacturer of folding cartons and solid-fiber partitions. The Ellis purchase included its Canadian subsidiary, Dominion Paperboard Products Ltd. With these additions RockTenn controlled 60 manufacturing and distribution operations, including eight mills with a total annual production capacity of 607,000 tons of recycled paperboard products. RockTenn now ranked sixth among U.S. producers of recycled paperboard, with market share of 5.7 percent.
