§ 29420 Slack-Filled Container Definition

• •A container is 'slack-filled' if it's less than 85% full.
• •This rule is about making sure containers aren't mostly empty.
• •It applies to closed containers, like bottles or boxes.

You buy a big box of cereal, but when you open it, it's only half full.

If the cereal takes up less than 85% of the box, it's 'slack-filled' and breaks this rule.
