Packaging Materials Explained: Cardstock vs. Kraft vs. Corrugated vs. Rigid

The material is what your box is made of – and it decides how strong it is, how it prints, how premium it feels, and how much it costs. It is a separate choice from the box style (the shape): the same mailer can be made in different materials. This guide explains the four materials you will actually choose between, in plain English, so you can match one to your product. All are available on our custom boxes with no die or plate fees.

Cardstock (SBS paperboard)

Cardstock – often SBS, or solid bleached sulfate – is a smooth, bright-white paperboard. It takes vivid print beautifully, which makes it the default for retail folding cartons: cosmetics, supplements, packaged foods, and more. It is lightweight, ships flat, and is the most economical material at higher volumes. Food-grade versions are available for direct food contact.

Best for: retail shelf products and high-volume runs. Common in folding cartons and cosmetic boxes.

Kraft

Kraft is an unbleached paperboard with a natural brown look and high tear strength. It is recyclable, often made with recycled content, and signals an honest, eco-conscious brand – which is why it is popular with organic, artisan, and refill-focused products. It prints well in a more earthy, natural palette.

Best for: natural and sustainable brands. See kraft boxes and custom kraft paper, and our sustainable packaging guide.

Corrugated

Corrugated board has a wavy, fluted layer sandwiched between flat liners – that flute is what gives it strength and cushioning. It is the material behind sturdy shipping boxes and e-commerce mailers, and it protects heavier or fragile goods in transit. It is also highly recyclable. Most everyday “cardboard boxes” for shipping are actually corrugated.

Best for: shipping, heavy items, and protective outer boxes. See corrugated boxes, cardboard boxes, and mailer boxes.

Rigid chipboard

Rigid board (thick chipboard wrapped in printed paper) is the heavyweight of packaging. It does not fold flat – it arrives pre-formed, which is what gives it that solid, luxury feel. It is the most premium and the most expensive material, reserved for products where the unboxing is part of the value.

Best for: luxury, gifting, and high price points. See rigid boxes.

Quick comparison

Cardboard vs. corrugated: what's the difference?

People use “cardboard” for almost any paper-based box, but it is a loose term. In practice, a thin printed retail box is paperboard (cardstock), while a strong shipping box is corrugated – the one with the fluted inner layer. If a box needs to survive the mail, you want corrugated.

Which material should you choose?

Three questions point you to the answer:

• Does it ship on its own? If yes, lean corrugated for protection.
• Is it sold on a shelf? Cardstock prints brightest for retail.
• How premium is it? Rigid for luxury; kraft for natural and economical.
