Why PBAT Filler

Biodegradable. Affordable.

Neat PBAT can be expensive. PBAT Filler compounds incorporate carefully selected mineral and bio-based fillers to bring the cost down dramatically while preserving the compostability that regulations demand.

Dramatic Cost Reduction

Reduce material costs by up to 40% compared to neat PBAT. Mineral fillers are significantly cheaper than biodegradable resins, making compostable products economically viable.

Still Compostable

Maintains biodegradability and compostability certification. The PBAT matrix still decomposes under industrial composting conditions as required by EN 13432.

Enhanced Stiffness

Mineral fillers improve the stiffness and dimensional stability of PBAT, which can be too flexible for some applications in its neat form.

Multiple Filler Options

Available with CaCO3, talc, starch, or bio-based fillers. Choose the filler type that best matches your performance requirements and sustainability goals.

Regulatory Compliant

Meets India's SUP ban requirements. CPCB-approved alternative to conventional PE bags and films. Export-ready with international certifications.

Standard Processing

Processes on the same blown film and extrusion equipment as neat PBAT. Pre-compounded for consistent quality and easy handling.

Applications

What You Can Make with PBAT Filler

1

Compostable Carry Bags

Shopping bags, garbage liners, and produce bags. The most cost-effective path to SUP-ban compliance for bag manufacturers.

2

Agricultural Mulch Films

Biodegradable mulch films that decompose in the soil after use. No removal needed — saves labour costs and eliminates plastic waste in fields.

3

Food Service Disposables

Compostable plates, boxes, cups, and containers. PBAT Filler provides the stiffness needed for food-service items at an accessible price point.

4

Industrial Packaging

Compostable shrink wrap, liners, and protective films. Meet corporate sustainability commitments without breaking the budget.
