Enzymatically biodegradable open-pore foam unlocks reusable absorbent packaging and disposable filters without long-lasting residues.
It forms an aqueous dispersion of an enzymatically biodegradable biopolymer plus a foaming agent, then dries it to create a dried foam with an open-pore network. The open pores increase internal surface area and absorption, enabling lightweight foams tailored by formulation before drying. Previously, deploying this specific dried open-pore foam approach required licensing rights and controlled supply of the patented formulation method.
Launch compostable absorbent pads and reusable packaging liners using dried open-pore enzymatic foam manufacturing.
A method for forming a dried absorbent foam having an open pore network by preparing an aqueous dispersion comprising an enzymatically biodegradable biopolymer and a foaming agent, then drying the foam to form a dried foam containing open pores. Gelled composites made from the foams are also provided.
