What is Kraft Paper?
You know that strong brown paper in shopping bags and moving boxes? That’s kraft paper. Its name comes from the German word for “strength” – and it definitely lives up to that name.
Look around and you’ll spot kraft paper everywhere. Those Amazon packages on your doorstep? Kraft paper. The bag holding your groceries? Often kraft paper too.
It’s become the go-to choice for packaging just about everything. Think about it – from tiny jewelry boxes to huge industrial wrapping, kraft paper shows up in all sizes and forms.
But why is it so popular? Well, it’s kind of like the superhero of the paper world. It’s tough enough to protect your stuff, but unlike plastic, it’s actually good for the planet.
Let’s take a closer look at what makes this simple brown paper so special, and why it’s become such a big deal in the world of packaging.
How Kraft paper is produced?
Ever wonder what makes kraft paper so tough? It all starts with simple wood chips and a special chemical recipe.
Wood chips get combined with sodium hydroxide, sodium sulfide, and water.
This mixture isn’t just random – it’s carefully measured to create the strongest paper possible.
These chemicals work together to break down the wood’s natural parts.
Think of it like untangling a knot – the process separates wood fibers in a way that makes them extra strong.
Super-Strong Results
What comes out is much tougher than regular paper. It’s harder to tear, can stretch without breaking, and stands up to pressure that would punch holes in normal paper.
Kraft vs Regular Paper
When you think of regular paper, writing paper is on your mind- thin, soft, easy to tear. But when it comes to packaging, it is where kraft paper comes into picture.
The main difference between kraft and regular paper is simple: kraft paper is much stronger. Let me breaks it down the differences:
Kraft paper is more robust
• Kraft paper is tough – great for packaging and heavy items
• Regular paper is perfect for writing, printing, and everyday use
• When you need something sturdy, go with kraft
Kraft paper can be used for packaging
• Kraft paper: Shopping bags, package wrapping, moving boxes
• Regular paper: Notebooks, printer paper, office supplies
Bottom line: Choose kraft paper when you need strength, regular paper for everyday use. It’s that simple.
Types of Kraft Paper
When selecting the optimal kraft paper for your packaging needs, it’s essential to understand the distinct varieties available in today’s market. Let me guide you through the main types you’ll encounter and help you make an informed decision for your specific requirements.
Brown Kraft Paper
It is the most stereotypical image of ‘kraft’ – brown in color and textured. Its natural brown color comes from unbleached wood fibers, creating an authentic and earthy appearance.
This material presents a cost-effective solution for packaging while maintaining environmental responsibility.
Consider using it for:
Corrugated boxes
Shopping bags
Eco-friendly packaging
Black Kraft Paper
If you’re looking to create a sophisticated, premium feel for your packaging or marketing materials, I highly recommend considering Black Kraft Paper.
What makes it particularly interesting is that the black pigmentation is integrated during the manufacturing process. It ensures consistent coloration.
Black Kraft Paper is becoming more and more popular in these packaging application:
• Retail Packaging:
- Luxury shopping bags
- Premium gift wrapping
- High-end retail boxes
- Brand packaging
• Food Service:
- Restaurant takeout bags
- Specialty food packaging

- Coffee bags
Solid Bleached Kraft (SBS)
Solid Bleached Kraft is one of the highest quality paperboard materials in our industry. SBS is made of 100% bleached chemical wood pulp.
What makes it exceptional is the white or off-white color.
Let me break down its key features that make it stand out:
• The pure white surface on both sides provides an excellent canvas for your branding
• You’ll appreciate its exceptional printability for sharp, vibrant graphics
• The strong, rigid structure ensures reliable product protection
• Its smooth surface finish enhances the premium feel
• The material offers superior folding properties for complex designs
Most importantly, it’s FDA-approved for direct food contact.
From my experience, SBS is particularly well-suited for these applications:
- Milk and juice cartons
- Excellent for food service containers
- medicine boxes
- healthcare product packaging
- beauty product boxes
- Excellent for perfume boxes
- luxury goods packaging
If you’re looking to convey premium quality and require excellent print reproduction, I strongly recommend considering SBS for your packaging needs.
Recycled Kraft Paper
Recycled kraft paper is manufactured by reprocessing used kraft paper and other paper products through a specialized recycling process.
It typically retains about 70-80% of the original strength properties.
What makes this material particularly appealing is its sustainablity.
If you’re considering recycled kraft, I’d recommend evaluating your specific requirements.
For general packaging and protective purposes, you’ll find it both cost-effective and environmentally responsible.
However, for applications requiring maximum strength, virgin kraft might still be your best option.
Let me outline its most suitable applications:
- Sustainable packaging
- Light-to-medium weight packaging
- Box and tray liners
- Dunnage and void fill
Specialized Kraft Papers:
For specific requirements, I suggest exploring these variants:
• Water-resistant grades for moisture protection
• Grease-proof options for food packaging
• Machine glazed kraft for smooth finish needs
• Sack kraft paper for heavy-duty bags
Remember, the key is matching the paper type to your specific application. I’d be happy to discuss your particular needs, WITPAX expert will ensure you select the most appropriate variety for your packaging solution.
Why Is Kraft Paper Eco-Friendly?
Kraft paper stands out as a true environmental champion in the packaging world, and here’s why it matters for our planet.
Natural Origins
It all starts with wood pulp from responsibly managed forests. Unlike plastic, kraft paper comes from renewable resources – trees that can be replanted and regrown. The manufacturing process is simpler and cleaner than many alternatives.
Earth-Friendly Breakdown
When kraft paper reaches the end of its life, it returns to nature without causing harm. It breaks down naturally in months, not centuries like plastic. Plus, it won’t leave behind harmful microparticles in our soil and water.
The Recycling Win
• Most kraft paper can be recycled up to seven times before the fibers become too short to use
Better Energy Use
The kraft process has become more energy-efficient over the years. Modern mills often use renewable energy sources and recapture chemicals used in production, making the whole process more sustainable.
Making a Real Impact
By choosing kraft paper, businesses and consumers help reduce plastic waste and support sustainable forestry. It’s a simple switch that adds up to big environmental benefits over time.
The future of packaging needs to be sustainable, and kraft paper is leading the way by showing that eco-friendly choices can also be practical and cost-effective.
