Product Overview
PHA Coated Cupstock Paper is a cutting-edge biodegradable paperboard solution for hot and cold beverage cups, food containers, and packaging applications. The PHA (polyhydroxyalkanoate) coating is derived from microbial fermentation — it is fully marine-degradable and home-compostable, offering a genuine alternative to traditional PE-coated paperboard.
Key Features
- 100% Compostable: PHA coating is certified home-compostable (TÜV OK Compost HOME) and marine-degradable, leaving no microplastic residue.
- Excellent Oil & Water Resistance: The PHA coating forms a continuous film that effectively prevents liquid penetration, ideal for both hot and cold beverages.
- Heat Resistance: Performs well at high temperatures — less prone to melting or deformation compared to traditional PE-coated cups.
- Recyclable in Paper Stream: PHA-coated paperboard can be repulped and recycled in standard paper recycling facilities, supporting circular economy goals.
