PHA Biopolymer at a Glance
| Material family | Bio-based, biodegradable polymer (PHA) |
|---|---|
| Typical hand-feel | Varies by grade; from flexible film to firmer mouldings |
| Best suited to | Films, coatings, components, accessories, packaging |
| Less suited to | High-heat structural uses, applications needing long-term inertness |
| Composition note | Polyhydroxyalkanoate produced by microbial fermentation |
| Certifications | Biobased-content & compostability verification on request |
This summary is qualitative and indicative; exact specifications, grades and documentation are confirmed per project during sampling.
What Is PHA Biopolymer?
PHA is a family of bio-based polymers produced by microbes rather than from petroleum. What sets it apart from many bioplastics is that it is genuinely biodegradable in a range of environments, including marine settings, under the right conditions. Being both plant-fed and biodegradable is the heart of its low-impact story, making it of growing interest for films, coatings and components. For a deeper introduction, read our material guides.
How Is PHA Biopolymer Made?
Microbes are fed renewable feedstocks such as plant sugars or oils and, under controlled conditions, accumulate PHA inside their cells as an energy store. The polymer is then harvested, purified and processed by familiar plastics methods such as extrusion or moulding into film, sheet or parts. Its microbial origin and biodegradability define the material.
Why Brands Choose PHA Biopolymer
- Biodegradable by grade: industrial, soil and marine routes vary by grade and certification, which we confirm per grade.
- Bio-based feedstock: made from renewable plant sugars or oils, not petroleum.
- Versatile processing: mouldable for fittings, hardware and small components.
- Strong end-of-life story: a credible answer to plastic-pollution concerns.

We would rather tell you early that a material is wrong for your product than have you discover it in production. Share your use case via our contact page and we will advise honestly.
Hand-Feel & Performance
PHA is a rigid-to-semi-flexible biopolymer depending on grade, used for components and fittings rather than as a textile. Its biodegradability, including in marine environments, varies by grade and certification, which we confirm per grade. We provide compostability and biobased-content documentation per grade.
Certifications Available
We work within recognised certification and verification systems relevant to PHA biopolymer, including TUV Austria OK Compost / marine-biodegradability standards, FDA food-contact for applicable grades, biobased-content verification. Documentation for specific grades is available on request as part of a sourcing conversation.
Sampling & Minimums
We keep sampling fast and minimums flexible, so emerging brands and established labels can both develop with us. Tell us your product type, target hand-feel and direction, and we will dispatch relevant swatches. We typically reply quickly to all sampling enquiries.
What We Can Supply PHA Biopolymer For
We supply PHA biopolymer for biodegradable hardware, fittings, trims, films and packaging. We can also support development with colour matching, specification selection and application guidance based on your construction method and product standard.
Frequently Asked Questions
Is PHA really marine-biodegradable?
PHA is one of the few biopolymers that can biodegrade in marine as well as industrial and soil conditions, by grade and certification. We confirm the standard per grade.
What can PHA replace?
It is well suited to small hardware, fittings, trims, films and single-use parts where end-of-life matters — a biodegradable alternative to conventional plastic components.
Is PHA bio-based?
Yes — it is made by fermenting renewable plant sugars or oils, not from petroleum.
