Brown Paper Bags vs Kraft Bags: What’s the Difference

If you are comparing brown paper bags and kraft bags for a school canteen, council event or office fit-out, the short answer is this: they are not two different products. “Brown paper bag” describes how a bag looks, while “kraft” describes what it is made from and how the paper is produced. Almost every natural brown paper bag on the Australian market is a kraft bag. The terms overlap far more than most product pages admit.

The distinction still matters for procurement, because once you understand what each word actually refers to, you can specify the right bag with confidence and avoid ordering thousands that do not suit the job. Here is what each term means and how to choose for your organisation.

What “kraft” actually means

Kraft is a paper-making process, not a colour. The name comes from the German word for strength, and the kraft process produces paper with high tensile strength, which is why kraft bags carry heavier loads than many other paper types at the same weight. That strength is the reason Kraft became the standard for carry bags, grocery bags and takeaway packaging.

Kraft paper can be left in its natural state or bleached. This is where the confusion between “brown” and “kraft” comes from.

What “brown paper bag” actually means

A brown paper bag is simply a bag with a natural, unbleached appearance. That warm brown tone comes from lignin, a natural compound left in the fibres when the paper is not bleached. In other words, a brown paper bag is almost always a brown kraft bag. The colour is the natural output of the kraft process with no extra whitening step.

So when someone asks whether they should buy brown paper bags or kraft bags, the more useful question is: brown kraft or white kraft, and virgin or recycled? Those are the choices that genuinely change how a bag performs and how sustainable it is. Buyecogreen’s full recycled paper bags range is built around natural brown kraft for exactly these reasons.

Brown kraft vs white kraft

Brown Kraft is unbleached. It keeps its natural fibres and its natural strength, needs minimal chemical treatment, and takes recycled content well. That makes it the more environmentally sound choice, and the reason it suits organisations reporting against sustainability targets.

White kraft is bleached to remove the lignin, giving a clean surface that prints sharply. The trade-off is a higher environmental footprint from the bleaching step, generally weaker fibres, and a material that is mostly virgin because recycled content disrupts the consistent white finish. For most institutional buyers focused on recyclability and recycled content, brown kraft is the stronger fit on both performance and credentials.
