For whom is flustix of importance?

Whether you're in packaging, manufacturing, or product development, flustix certification allows you to distinguish your brand by reliably showcasing your commitment to plastic sustainability and environmental responsibility.

By obtaining flustix certification, you not only differentiate yourself from competitors but also demonstrate to your customers (B2B and B2C) directly at point of sale that you prioritize and offer plastic-conscious choices.


The flustix certification scheme holds significant relevance for businesses and manufacturers striving for sustainable practices, particularly those in industries who want to show that there products are low in plastic or microplastic-free.

All production stages along the supply chain are certifiable, from consumer goods to products, semi-finished products, raw materials and packaging. To clearly declare the certified goods to end consumers, business partners and/or other affected parties, the labeling is done according to four specific categories:

  • TOTAL PRODUCT: This flustix seal evaluates both the product and its packaging. Each component is independently assessed and must meet specific criteria in its respective category to qualify for successful certification of the total product.
  • PACKAGING: Plastic in consumer goods packaging can often be significantly reduced. Packaging that is at least 95% plastic-free is eligible for the green seal based on PPWR.

* To promote innovation, seal graphics and certificates declare verified plastic contents of maximum 3.5% or 2% upon successful certification.

  • PRODUCT: This flustix certification seal is for plastic-sustainable products (without packaging) and its certification requirements are based on the specific product category.

* Seal shows exemplary limit value. Specific limits apply for each certified product category: General max. 0.2%, exceptions for virgin fibre products max. 2% with declaration of max. 1.25% or 0.75% plastic content and recycled fibre products max. 3%. flustix LESS PLASTICS certification scheme, Edition: July 2024.

  • PRODUCT CONTENT MICROPLASTIC-FREE: This flustix seal certifies liquid product content or products performing in liquid state that do not contain microplastics. The certification is based on ECHA and REACH.
