The term ‘kraft paper’ probably makes you think of a few things.
You might picture mum wrapping up your sandwiches for school lunches
You might think of nothing more than a scrunched up piece of paper in your Amazon delivery.
It might be something you use regularly for craft projects - kraft paper = craft paper, right?
But it might surprise you to hear that in its most simple form, kraft paper is cardboard.
Layers of brown wrapping paper laminated together make the traditional corrugated cardboard box.
But it's also used as a flat, thin sheet.
This leaves it to solve hundreds, possibly thousands of problems, but also have heaps of names:
Brown paper, butcher paper, recycled wrapping paper, packing paper - the list is somewhat endless.
That's because this simple brown paper can benefit your business.
It aids security, branding, environmental impact and saving money.
And you’re about to see how.
In this article, you'll see:
- What is kraft paper?
- How is this brown paper made?

What is kraft paper?
Kraft paper is a naturally biodegradable material.
It's used in a wide range of industrial and commercial operations for packaging and protection.

It’s natural ‘woody’ looking texture means that it’s suited to a wide range of branding options, too.
The name is from the German work Kraft which translates to ‘force’ or ‘strength’.
Here’s how it gets that strength:
How is kraft paper made?
Back in the late 1800s, Engineer Carl F. Dahl was working in a paper mill.
His job was to create the best possible paper products.
A few types of paper turned out to not be strong enough for their intended use.
So Dahl started to change the chemicals used throughout the production process.
When woodchips come into the paper mill to be turned into paper, they’re crushed up and mixed with an adhesive.
Dahl found that once ground to a pulp, treating one of the elements of the woodchips with sulfates made the final material stronger.
Hence the name kraft paper - literally strong paper.
After discovering the true strength and versatility of this new material, it quickly became a staple for the packaging industry - and, the food industry.
This new product was a cost-effective solution that, after being coated in wax, was great for meat. Hence the name 'butcher paper'.
Brown paper types
There are a few different types of brown kraft paper that are out there.
The biggest differences are the types of fibres the material is made of (virgin or recycled), but there’s also a difference in the finishes.
Coated Unbleached Kraft Paper is the most basic and common form of brown paper. There’s no altering of the colour, giving it that natural look.
It’s very resistant to tears and can be stiff without being heavy and solid.

Coated Kraft Paper is usually a brown paper that's had a white additive added to make it more of a 'blank' canvas.
Some of the natural texture shows through but rather than being brown in appearance, it’s white.
That makes it a great blank canvas for other colours, and it’s used on Packhelp’s Eco Colour Mailer Boxes

But kraft paper can be covered in any colour.
Below you can see how Demagica has used completely black kraft mailer boxes and negative space to create an eye-catching design:
Here are the types of material that are used in both Coated Unbleached and Coated kraft paper:
Virgin kraft paper
Virgin kraft paper is made from raw pulp. This is wood that has come straight from the tree and is processed into brown butcher paper.
This is the strongest form of brown paper and is used when structural integrity is most important.
For example, in corrugated mailer boxes and kraft packaging tape
Recycled kraft paper
Recycled kraft paper is made from recycled materials. Cardboard boxes, books and other materials are broken down back into pulp and turned back into recyclable brown paper.
This is a great option for brands that want to use sustainable packaging in their supply chain.
Recycled kraft paper is often used in product boxes, paper bags and paper cans.

Mixed kraft paper
This mixed paper is made from both virgin and recycled pulp. It has the benefits of being strong like virgin pulp, but also cheaper and more ethical thanks to its recycled content.
Mixed brown paper is used in cardboard envelopes and other postage boxes.
Benefits of kraft paper
The main benefit of recycled brown paper is that it’s exceptionally strong, which is a result of it’s increased sulfur and decreased lignin content.
This stronger form of paper has a lot more durability than alternative materials in most planes and is a lot more resistant to piercing than paper.
Brown paper can be made from many types of wood, like pine, bamboo and oak.
This means it's easier to create, so there's an abundance of it available - this fosters a lower material cost.
The quality of wood can be quite broad, meaning that high and low-density woods can be mixed.
A lot of kraft paper is made from imperfect trees that aren’t fit for other functions.

As it retains its natural colour and texture, it doesn’t need the extra step of being bleached.
This saves money as the material has to be handled less, and keeps chemicals out of the environment.

Waxed kraft paper was traditionally used to wrap meat, as you read earlier.
The wax coating is what made it ideal for wrapping, as it was somewhat water and moistureproof.
This was a cost-effective solution that led to the alternative name of 'butcher paper'.
The chemicals that are used in creating kraft paper are easily recovered and reused, again and again, fostering a circular economy.
Byproducts of the kraft paper manufacturing process, like tall oil, go on to be processed again and used in asphalt and fire-starting bricks.
Kraft paper & packaging
Pure brown paper is a popular element in product packaging.
It can save your business time and money thanks to its versatility as a packaging material.
Corrugated cardboard made of kraft paper is the default shipping option for many reasons.
- It’s lightweight
- It’s durable
- It’s cheap
- It can be custom printed
Since it’s lightweight, corrugated kraft boxes don’t add any extra weight to your item.
Keeping the overall weight of your item down means less shipping costs for you to absorb or pass onto your customer.
Kraft paper packaging supplies
Kraft paper is great for filling up space inside a box. We've all seen Amazon and other big brands go hard with their bad packaging:
The fact that it’s lightweight while still being somewhat sturdy means that it can keep the contents of a box safe from thrashing around inside.
Being durable, kraft paper is a great addition to your packaging supplies, but it's also great at wrapping products to protect them.
Custom printed butcher paper is a great option for brands that want to leverage the ‘natural’ texture of kraft paper, but also build an unboxing experience.
Kraft paper branding & design options
The natural, wood-like texture is thanks to the unbleached pulp that when processed, looks a lot like the natural texture of raw wood.
This makes it a fantastic ‘blank’ canvas for many brand types.
Brands that use minimalism as a design concept often use the simple texture of kraft paper as a way to focus on that ‘less is more’ idea.

Because of its natural look, many ‘eco-friendly’ brands use kraft paper in their branding.
The look and texture gives an earthy, woody feel and helps resonate with customers that are looking for an unprocessed, ‘raw’ product.
See how Slopes & Town use their kraft boxes to complement the internal fit-out of their retail store.
Eco benefits of brown paper
Kraft paper is a pretty environmentally friendly material for a number of reasons.
Virgin pulps used in Packhelp products, including kraft paper, are all FSC certified.
This means while your material made be made from new, raw material, it’s grown, harvested and processed in a way that’s manageable, ethical, and most importantly, renewable.
If you take coated unbleached brown paper, or corrugated cardboard and throw it into your garden, it’ll start to naturally compost.
Within a few weeks, it will have disappeared back into the ground, and (providing that there are no nasties in the ink) there will be no trace of your brown packing paper left.
This process doesn’t release any bad chemicals into the soil, either.
Economics of scale
If you were to create your recyclable brown kraft paper from your own trees, it’d be pretty labour (and energy) intensive.
But since kraft paper and cardboard are such a widely used product, the production and recycling process is incredibly efficient.
If a brand wants to minimise its carbon footprint, brown paper and cardboard are a great option.
Not only is the product process energy efficient, but the end product is also completely recycled and also recyclable.
Kraft paper is something we come across daily.
Its versatility for both boxes and paper gives it a place in your packaging suite as both the protector and a canvas for your branding.
