Packaging

Packaging is where sustainable polymers earn their living. It's the single largest market for bioplastics, the place where PLA and PBAT already compete head-to-head with fossil plastic, and where regulation is pushing hardest.

Why packaging leads

Most packaging is used briefly and discarded, which makes its end-of-life footprint enormous, and also makes it the most logical place to deploy materials designed to compost or to carry recycled content. It's no accident that packaging is the biggest single application for bioplastics worldwide. Consumer visibility helps too: a clear PLA cup or a compostable bag is something a customer can see and a brand can market.

What fits where

  • Clear rigid items (cups, deli trays, clamshells) → PLA for its glass clarity and food-contact approval.
  • Flexible films & bagsPBATstarch blends, which combine flexibility, strength and compostability.
  • Bottles & durable packagingbio-PE / bio-PET drop-ins that recycle in existing streams.
  • Paper & board → bio-based barrier coatings replacing PFAS and PE liners on cups and cartons.
  • Items likely to leak into naturePHAfor its soil and marine biodegradability.

What's driving the shift

Regulation, mostly. Across major markets, packaging rules are tightening on recyclability, mandatory recycled content, and substances of concern, and that regulatory pressure is the strongest single demand driver for sustainable packaging materials. Single-use bans are simultaneously removing conventional options and, in some cases, creating exemptions that favour specific bioplastics. Brand sustainability commitments add a second pull.

The honest version

Sustainable packaging only works as a system. A compostable tray is worse than useless if it goes to landfill or contaminates PET recycling, the material is only as good as the disposal route available to the person holding it. The hard questions in packaging are rarely "which polymer?" and almost always "what happens after use, where this product is actually sold?" Match the material to the real-world end-of-life, not the ideal one.

Start with the materials

Packaging draws on nearly every material in the hub. The most-used: PLAPBATstarch blendsand drop-ins.
