Biofibre® Solva
Biofibre® Solva - virgin
Biofibre® Solva - recycle
Biofibre® Solva is a material blend of a wide variety of biopolyesters. The name “Solva” is derived from the Latin origin “solvere”, meaning “to dissolve”, and indicates the possibility of soil degradability of this product type.
Why and when to use Solva
- Ability to degrade in soil
- For flexible products
- Substitute for e.g. LDPE, EVA.
- Example applications: Tree protection
