Slack fill: How much is too much?
Consumer Reports investigation questions the need for extra space in packaged goods.
-- Packaging Digest, 12/2/2009 12:49:58 PM
A recent Consumer Reports investigation turned up several products with packages that are as much as half empty. Those include One A Day Men's 50 + Advantage vitamins, where the plastic 50-tablet bottle looks about 40 percent empty, and Lay's Potato chip bags that are half-filled.
Other products with ample wiggle room include Mrs. Paul's Lightly Breaded Tilapia Fillets, Pasta Roni Garlic & Olive Oil Vermicelli, and Quaker Oatmeal to Go Brown Sugar Cinnamon bars.
Relying mostly on nominations from readers, Consumer Reports rounded up a handful of products and asked the companies behind them for an explanation of all that air-to-spare. Packages CR looked at are examples of what is likely to be found on store shelves, and don't necessarily represent the worst offenders out there.
"We get a lot of questions from frustrated readers asking why such packages are often so large relative to the amount of product inside," said Tod Marks, senior project editor, Consumer Reports. "But even when extra space is perfectly legal, it's natural to wonder whether you're getting the amount of product you paid for."
The federal Fair Packaging and Labeling Act is supposed to prevent the public from being misled by packages containing excessive “slack fill,” nonfunctional or empty space that creates an illusion of more product, often through underfilling, indented bottoms, or extra walls. But slack fill is allowed if it keeps a product from breaking, if the package does double-duty (as a dispenser, or a tray, for example) to accommodate machinery on the assembly line, or to discourage theft in the store.
According to Consumer Reports' investigation, the law gives manufacturers plenty of wiggle room. The FDA hasn't acted against a slack-fill violation in five years.
The full results of CR's investigation is available in the January 2010 issue of Consumer Reports on sale at newsstands December 2 or online at www.ConsumerReports.org.
A Frito-Lay customer rep confirmed that Lay's potato chip bags are half-filled. Delicate items pose several challenges. Chips can be broken by rollers on the packing line or pressure from machinery that seals the bags. A Post rep who responded to the question why Shredded Wheat boxes have extra air said that the company can't overfill because cereal can get caught near the top of the bag, resulting in an improper seal.
In the examples of slack-fill cited in Consumer Reports, net weights were labeled correctly. But Consumer Reports doubts that most consumers really know what a given weight of a product should look like.

Nestles Ovaltine Rich Chocolate Mix (12oz.)has 32% nonfunctional slack fill in a product with very little if any settling. Where is the line drawn with regards to deceptive packaging for a product such as this?

If you question the fill rate and "air space" in the bag take the package home and weight the contents and I suspect all you worry-worts will actually see you're buying what's labeled on the package

It does not take a bag with 50% air to "protect" the product from breakage. Individual serving bags have a far smaller ratio of air to product than do large "take home" quantities. The chip companies do not want consumers to become turned off by how little they really are getting for the money.
