Kraft Paper or Plastic: Which Is More Sustainable?
Is kraft paper more sustainable than plastic? Not across the board. What matters is the structure, the protection and the disposal route. Pure paper bags are plastic-free, but protect less against moisture and grease. Kraft paper stand-up pouches have a film inside and are composites, which are harder to recycle. Mono-PE bags protect well and are recyclable as a mono-material.

Three types compared
| Feature | Pure paper bag | Kraft paper composite | Plastic bag (mono-PE) |
|---|---|---|---|
| Example in our range | Block Bottom Bags in Natron Kraft (kraft paper 70 g/m² with parchment substitute) | Kraft-Paper Stand-Up Pouches (kraft paper 50 g / AL 7 / CPP 60) | Recyclable Stand-Up Pouches (LDPE / EVOH / LDPE) |
| Visibility of the contents | no, unless it has a window | no, unless it has a window | yes, transparent |
| Protection against moisture and grease | limited | high thanks to the inner film | high |
| Plastic-free | yes | no, inner film | no |
| Disposal | waste paper (usually) | composite, harder to recycle | plastic recycling, mono-material |
| Look | natural | natural | clear or printed |
What sustainability in packaging depends on
- Structure: A mono-material can be recycled by type, while a composite of paper and film can only be recycled to a limited extent.
- Disposal route: Pure paper generally belongs in waste paper, films in plastic recycling. For composites, recovery depends on the sorting facility.
- Protection: Packaging that does not protect the goods causes losses. That belongs in the assessment.
- Material and origin: According to the item data, the paper carrier bags in our range are FSC-certified, and some bags have recycled content (for example rLDPE).
- Verifiable claims: We do not describe any item across the board as more sustainable or environmentally friendly. The evidence for the specific item is what counts.
Where paper scores
- Natural look for farm shops, bakeries and small-batch producers.
- Paper carrier bags made of kraft paper (70 and 80 g/m², FSC-certified, recyclable): Paper Carrier Bags.
- Dry goods such as spices and tea in Block Bottom Bags in Kraft Paper.
Where plastic scores
- Transparency: customers can see the product.
- Barrier against moisture, oxygen and aroma loss with little material.
- Vacuum packing, sous vide and freezing, see Sous vide and vacuum bags.
- Recyclable mono-materials: Recyclable Stand-Up Pouches.
The key points first
A bag that looks like paper is not automatically plastic-free. Whether paper or plastic, what matters is the structure and the disposal route. If you need plastic-free, choose pure paper bags. If you want to combine shelf life and recyclability, look at mono-materials. Legal questions on recyclability and labelling are covered in our PPWR guide.
Frequently asked questions
Is kraft paper more sustainable than plastic?
Not across the board. It depends on the structure, the protection and the disposal route. A pure paper bag is plastic-free, a kraft paper stand-up pouch with an inner film is a composite, and a mono-PE bag is recyclable as a mono-material.
Are kraft paper bags organic packaging?
Not automatically. Kraft paper is a renewable raw material. The term biodegradable or compostable should only be used if there is proof for the item, for example according to EN 13432. The information for the specific item is what counts.
Is a kraft paper stand-up pouch plastic-free?
No. According to the item data, it consists of kraft paper on the outside and a film on the inside, for example CPP or PLA. It is a composite.
What is a pure paper bag?
A bag made entirely of paper; in our range, for example, the Natron block bottom bag made of kraft paper with parchment substitute.
Is kraft paper food-safe?
Most kraft paper items in our range are marked as food-safe. What counts is the information given for the specific item.
Which packaging is better for the environment?
That depends on the structure and the disposal route. Mono-materials can be recycled well, pure paper bags are plastic-free, and composites are harder to recycle.
