PHA has transitioned to commercial scale, focusing on specialized grades and reliable PLA blends. These innovations allow injection molding operations to evaluate and adopt materials on existing lines, meeting environmental and regulatory requirements for alternatives to ABS and PP.
Why Adopt Now?
- ✔ High Bio-content preservation
- ✔ No Tooling Changes required
- ✔ Meets EU & China restrictions
Key PHA Grades in Use
Available for sampling and production-scale applications
aPHA (Amorphous PHA)
e.g., PHACT aPHA
Soft and rubber-like (Tg ≈ -17°C). Delivers high impact toughness and low-temperature stability.
Real Example: Banila Co. Clean It Zero & Wakemake Velvet Cushion.
Semi-Crystalline Grades
Injection/Blend Types
Heat deflection up to 130°C, fast crystallization for shorter cycles and solid mechanical properties.
Real Example: RIMAN INCELLDERM (>540k units/yr).
Other Commercial Grades
Flexible & Moisture Resistant
Fully degradable in marine/soil (18 months, no microplastics). Includes food-contact approvals.
Focus: Strategic sustainability goals.
PHA-PLA Blend Performance
| Blend Ratio | Main Improvements | Packaging Benefit | Commercial Example |
|---|---|---|---|
| PLA + 10% aPHA | Impact strength ×2-3; composting -30 days | Better drop resistance; faster composting | Banila, Wakemake |
| PLA + 20-30% aPHA | Higher tear resistance; greater elongation | Flexible/semi-rigid (tubes, caps) | RIMAN INCELLDERM |
| PLA + aPHA (Trans./Opa.) | Improved blow/film; puncture strength | Flexible pouches; clear premium containers | 2025 In-use Compounds |
aPHA addresses PLA brittleness and accelerates composting (home/industrial) with zero microplastics, matching traditional plastic textures.
