The history of kraft paper

As the name suggests, this is particularly resistant paper. The secret of its strength lies in the fibers that are used. Kraft paper can be produced from various types of wood. Long-fiber softwood pulp is preferred for the production of kraft paper - but alternative raw materials such as hay can also be used for production. The extraction of fibers from softwoods is done with the so-called sulfate process. In this process, wood chips are heated in boilers at high pressure. With the addition of sodium sulfate, lye and sulfide, the pulp is separated in a process lasting several hours.

Since long fibers are needed to produce this strong paper, blending with waste paper is suboptimal. This is because waste paper consists of a high proportion of damaged or very short fibers. This would cause paper to lose strength. Kraft paper is usually produced with a grammage of up to 120 g/m². Paper with a higher grammage then belongs to the so-called kraft liners, which are used in corrugated cardboard production.

As your contact for top-quality packaging solutions, we have put together a wide-ranging portfolio with many different Doypack designs for you. In our store you will find stand-up pouches made of kraft paper for every application. And what doesn't fit, you simply make to fit: Each design can be flexibly adapted to your wishes.

Alternatively, you can configure the size of your stand-up pouches made of kraft paper so that they are tailored exactly to your ideas and the respective requirements. With regard to the dimensions you have a very large framework at your disposal.

From these figures you can create your personal doypack:

• Lengths: 80 to 500 mm
• Widths: 65 to 95 mm
• Heights: 160 to 380 mm

WE STAND FOR SUSTAINABLE AND HACCP-CERTIFIED PRODUCTION

You can design the free as well as the fixed formats yourself and configure them according to your ideas. For example, you can specify whether your stand-up pouch should be made of kraft paper with or without a tear-off tab and suspension. You also determine the material and the printing on the outside with just a few clicks. You even determine the production time yourself.

Here you can choose between Economy (14 working days production time) and Express (10 days production time). Both types of production are of course HACCP certified. This ensures that you can order stand-up pouches made of kraft paper for food and pet food from us at any time.

Stand-up pouches made of kraft paper: you can rely on these materials

We offer you two different types of kraft papers as base material for your stand-up pouches from packaging warehouse: a white and a brown uncoated paper. Both versions have an excellent high barrier against oxygen, carbon dioxide and aroma loss.

Thanks to its specific composition, our kraft paper has a particularly high strength. This makes the material very sturdy and resistant as well as tear-resistant. Another plus point is that the special paper has a very smooth surface, which is ideal for printing with a high-quality print image.

The structure is identical for both variants. The basis weight, or paper thickness, is made up of several components. The paper component has a grammage of 60 g/m², while polyethylene (PE) adds an additional 7 g/m². Ethylene vinyl alcohol (EVOH) is also added.

The ratio of recyclable cardboard to PE is approximately 89:11.

This is how you increase the practical benefit and the visual appeal

To stand out from the crowd of competing offers, you can refine your Doypacks with various additional options. The tear-off tab makes it easier for your customers to open the pouch. However, you can improve the handling even more by choosing a zipper as a practical closure.

This way, your customers can not only easily open the pouch, but also safely reseal it. The already opened pouch can be transported easily and continues to protect the flavors inside the Doypack.

For perfect presentation at the POS, you can also choose from optional hole suspensions and standardized Euro slot hangers. However, always keep in mind that the attachment of such additional options affects the maximum filling quantity. If you are unsure, please do not hesitate to contact our team.

Different filling quantities for different products

Goods differ in many respects. One factor that plays a particularly important role when selecting the right pouch packaging is the weight. We have created a small table that gives you an approximate idea of how your pouches can vary in size depending on the product to be packaged.

As you can see, the filling quantities always vary with the characteristics of the respective product. So the configuration of the perfect size of the pouch is always individual.
