Biodegradable mulch films and materials made from bio-plastics: we guide you through certification | DIN CERTCO

Biodegradable in Soil - Indispensable Test Mark for Mulch Films

Certification for biodegradable mulch films, materials and intermediates according to DIN EN 17033.

Mulch films help protect plants, improve soil and increase yields in agriculture and gardening. But not all of them are equally suitable. For example, the remains of conventional mulch films have to be collected after use. More and more agricultural and gardening businesses are therefore switching to biodegradable mulch films. Their unique advantage is that they can simply remain in the soil after their period of use.

Important for you as a manufacturer or distributor of mulch films: Your customers pay close attention to the biodegradable properties of the products. With certification from DIN CERTCO, you can prove that your mulch films meet all the requirements of the standard and are marketable. Get the test mark „DIN Geprüft – Bioabbaubar im Boden“ (DIN Tested – Biodegradable in Soil) - this way you create transparency and trust among your customers.

  • Infrared transmission spectrum

Especially for mulch films additionally:

  • Dimensions, mechanical and optical properties
  • Designation and marking of the product

The tests are carried out in a testing laboratory recognized by DIN CERTCO. First, we evaluate the material composition and determine the testing scheme. If your product meets the above requirements, you will receive the corresponding certificate and may use the "DIN Tested - Biodegradable in Soil" mark for your mulch films.
