Every box tells a story.
That small stamp on the bottom of a corrugated box is more than just letters and numbers. It’s the Box Maker’s Certificate, and it helps show how the box was built and what it’s designed to handle. That means helping customers understand the details that matter, like box strength, construction, and performance.
Here’s the simple version:
📦 The stamp helps identify the box’s construction and strength.
📦 It can show whether the box is designed for burst strength or edge crush strength.
📦 It gives shippers and manufacturers a clearer picture of what the box can support.
Strong packaging starts with smart choices. And the right information helps brands ship with confidence.
