Reducing Risk for Slack-fill Packaging Lawsuits: Part One

Here are some fundamentals regarding lawsuits alleging that the packaging contains slack-fill that misleads and deceives the consumer.

Slack Fill Lawsuits

In recent years, there has been a parade of lawsuits against various brand owners about the amount of slack-fill in their packaging. The majority of the defendants have been from the food industry, although other categories are not exempt.

The federal regulatory framework associated with slack-fill packaging is as follows: the Food, Drug, and Cosmetic Act (FDCA) grants regulatory powers to the Food & Drug Administration (FDA); FDA regulations are published in the Code of Federal Regulations Title 21 (21CFR); and, 21CFR §100.100 defines slack-fill as, “the difference between the actual capacity of the container and the volume of product contained therein.”

According to the FDCA, a food is misbranded if its container is “made, formed, or filled” misleadingly. Code of Federal Regulations 21CFR §100.100 builds on the “filled” requirement, namely, “A container that does not allow the consumer to fully view its contents shall be considered to be filled as to be misleading if it contains nonfunctional slack-fill.”

Slack-fill is not inherently bad, however. By mentioning nonfunctional slack-fill, 21CFR §100.100 implies the existence of functional slack-fill, which does not constitute misbranding. The Section goes beyond implying and enumerates six exceptions.

(1) The slack-fill is needed for product protection. Example: fragility (or other characteristics) of the product renders it vulnerable to damage if filled more compactly.

(2) The slack-fill is the result of machinery requirements. Example: the filling machine is engineered and calibrated for a given package size, at a given contents volume.

(3) The slack-fill is the result of unavoidable product settling. Example: vibrations encountered throughout the supply chain, and even at the filling station, reduce the fill line.
