Package Downsizing Proves That Less Is Not More

F ew things are more infuriating than tearing into a bag of chips to find that it’s mostly filled with air, or digging into a “pint” of ice cream that—on closer inspection—is only 14 ounces. How can they cheat us like this? consumers often ask. There oughta be a law!

Technically, there is a law—the almost 50-year-old federal Fair Packaging and Labeling Act. It prohibits excessive “slack fill,” or nonfunctional empty space that creates the illusion of more product through underfilling, overpackaging, or other tactics. But the law has loopholes. When we contacted the Food & Drug Administration to inquire about violations, and a recent citation it might have issued, the press officer referred us to a database in which we could find neither details of violations nor warnings to manufacturers.

California is one of a few states in which local officials are cracking down. In late August, StarKist agreed to settle a class-action lawsuit brought by Patrick Hendricks in U.S. District Court for the Northern District of California, accusing them of underfilling various 5-ounce cans of chunk light and solid white tuna for more than five years. StarKist denied wrongdoing but has agreed to distribute $8 million in cash and $4 million in vouchers redeemable for their tuna products. (You can file a claim until Nov. 20; go to tunalawsuit.com.)

Larry Barlly, supervising deputy district attorney in Yolo County, Calif., told us that since 2009, 27 slack-fill cases have been settled in civil penalties against companies including Coty, CVS, Hershey, Johnson & Johnson, Mars, and Walgreens. As part of the settlements, the companies were also compelled to redesign their packaging.

Other cases are pending elsewhere. This past March, in New York, 100 consumers joined a class-action suit against Johnson & Johnson Consumer Companies and McNeil-PPC accusing the manufacturers of using disproportionately large bottles to house a small number of Motrin IB and Motrin PM capsules.

“Most every pharmaceutical issue is tied to regulatory matters, so any change to packaging materials (say, to a different-sized bottle) could mean expensive investments and time-consuming review and approval from the [FDA or another] agency,” said Jim Butschli, an editor at the trade publication Packaging World.

“You and I may be outraged, but there might be a function to the slack fill,” said food and drug lawyer Eric Greenberg.
