New packaging for our insole blanks

New packaging for our insole blanks

We have changed the packaging for the production of our insole blanks

Since the beginning of 2021, we have been shipping our insole blanks in environmentally friendly paper bags.

The previous packaging of our paper insole blanks.

Paper is made from renewable wood, while the plastics we used to package our insole blanks are made from finite petroleum.

So everything is clear, isn’t it?

Unfortunately not, because you have to differentiate:

  • Does the wood come from sustainable forestry?
  • Is the plastic used recyclable?
  • Can the end product be recycled?
  • How much energy does the production process consume?

The fact is that paper packaging is up to twice as heavy as plastic alternatives with the same tear strength, offers only limited product protection. Above all, paper requires significantly more energy, water and chemicals for production.

In addition, paper bags have not proven to be particularly suitable for us in practice. The bags are difficult to store and the most important reason: you can’t really see the contents. You can see which model is in the bag by looking at the label. However, with over 500 different models now available, it is very time consuming to always read the label or even open the bag to check the contents.

We always strive to work to the complete satisfaction of our customers. That’s why we went in search of a better solution that is also sustainable. And we have found it!

The new packaging of our insole blanks made of LD-PE.

We will gradually pack our produced insole blanks in flat bags made of recycled LD-PE. These bags have a pressure seal, are transparent and, of course, reusable.

This is because recycling technology for plastics continues to develop and the supply of recycled plastics is growing. Biologist Isabell Kuhl’s unequivocal vote:

“At present, so-called monoplastics are the most sensible alternative for many products. These can be recycled well, require comparatively little energy and combine excellent packaging properties.”

We have thus found a compromise for our packaging of insole blanks between sustainability and practicality.

A little information about PE (polyethylene / polyethylene)

PE has these properties:

Polyethylene has a high density to water vapor and grease. It is also resistant to cold and welds very well. Since it can be easily processed into a film, it is often used for foils. LD-PE is also very easy to recycle.


In contrast to HD-PE, LD-PE has a low density (high pressure). This makes the material translucent and clearer than HDPE. At the same thickness, it is less tear-resistant than HDPE. It hardly tears further if it gets a crack. LD-PE is a high-quality, smooth and glossy film that is also soft. Another advantage: LD-PE is very recyclable.
