In the design of its materials Sulapac pays great attention to all phases of the material life cycle. Sulapac’s co-founders have their academic background in biomedical*) materials, which means that safety is in the DNA of all Sulapac’s products. Naturally, when we say a product is safe, we say it is safe for its intended use.

Promotion of circular economy is one of Sulapac’s key priorities. By designing materials, the raw materials of which are inherently safe for people and the environment we can promote cycles which are safe on the molecular level. Our ambitious objective has been to develop ‘bio-benign’ materials that would reduce the negative impacts on natural systems when leaked, while also being recyclable and competitive in terms of functionality and costs. Our leading design principle is to mimic the nature.

*) Biomedical materials are materials which are biocompatible meaning they can be placed in human body on medical purposes


Sulapac straw is safe for people and the environment. The main raw materials of the Sulapac straw are sustainably sourced wood chips and biodegradable binders. All raw materials are sustainably sourced and food contact approved. During the use and end of life of the Sulapac straw there are no releases of ecotoxic chemicals or microplastics.

Criteria and validation


  • All raw materials are food contact approved according to EC Regulation No 1935/2004
  • All raw materials are GMO-free
  • All raw materials are compliant with EC Regulation 1907/2006 (REACH) to the extent that they are being supplied from within the EU or the European Economic Area. REACH compliant means that all relevant substances are:
    • excluded from the regulation, and/or
    • exempted from registration, and/or
    • had been manufactured/imported under a valid pre-registration until May 31, 2018 and/or
    • have been registered.
  • A third- party assessment conducted by a US laboratory has ensured that there is no risk of exposure to Proposition 65-listed substances. In the Sulapac Straw the wood chips are fully impregnated into polymer and therefore, there are no loose particles in the material. The material is thus a solid composite and there are no concerns with regard to the Proposition 65 (California legislation**).
  • The binders used are biodegradable polymers and comply with EC Regulation No 10/2011
  • The raw materials don’t include any adhesives


**) Since the beginning of the program in 1986, California has listed over 900 substances in its Proposition 65 initiative which are potentially carcinogenic or may cause reproductive toxicity. The Program is administered by California’s Office of Environmental Health Hazard Assessment (OEHHA).



  • Migration tests specified in Commission Regulation (EU) No 10/2011, have been be conducted to demonstrate the compliance of straw to be used with foodstuff. Sulapac straw is suitable for aquatic, acidic and alcoholic foods and milk products up to 24 hours and temperatures up to 40°C


  • Sulapac recipes do not contain any deliberately added micro-size plastic particles (primary microplastics), neither do the Sulapac materials produce microplastic particles due to degradation or wearing (secondary microplastics). (For details see the Key feature Microplastic-free)



  • Sulapac straw has been successfully tested by a third-party laboratory according to EN 13432 (industrial composting), which in addition to disintegration and biodegradation tests also includes the verification that the degradation products
    • are not ecotoxic and
    • do not exceed the threshold values for heavy metals


  • Sulapac straw has passed the Daphnia magna plankton toxicity test (according to OPPTS 850.1010 & OECD 202) performed by a third-party laboratory
    • test series showed that the degradation products of the Sulapac straw are non-toxic, and therefore, do not have any harmful effect on the plankton in the marine ecosystem.
