If you run an online shop, you’ve probably spent a fair amount of time staring at boxes, wondering which one will actually get your product to the customer without arriving in a crushed mess. It’s easy to call everything “cardboard,” but that’s a dangerous habit to get into. In the world of shipping, “cardboard” and “corrugated” are two completely different beasts. One is meant to look pretty on a shelf, while the other is an industrial-strength shield for your goods. Getting this wrong doesn’t just look unprofessional; it’s a direct hit to your profit margins.
When you think of a standard cereal box or a shoe box, that’s what we call cardboard—or more accurately, paperboard. It’s essentially one single, dense layer of heavy paper. A cardboard box is manufactured from a single, thick layer of heavy paper stock, often referred to in the industry as paperboard or chipboard.
Because it’s just one sheet, it’s thin, pliable, and easy to print on. It’s perfect for retail displays where the box needs to look sharp and fold cleanly. You’ll often see these used as cardboard postal boxes or flat-envelope boxes for items like stationery or t-shirts. But don’t be fooled: if you put anything heavy in there or send it through a busy courier hub, it’s going to crumple. It has no internal structure to withstand shipping pressure.
