BIOFOAM
##GENERAL INFORMATION
A thin, textured sheet, and half domes of foamy, flexible bioplastic. Gelatine-based. The biofoam feels like the foam-like packaging materials sometimes used for shipping fragile goods or thick foamy kitchen cloth. It feels colder to the touch and is slightly stickier. The upside shows visible bubbles, but the mold-facing side feels very smooth if the mold had a smooth surface. It somewhat keeps the smell of the dishwashing liquid and smells less like wet dog than other gelatin-based bioplastics.
The foam half domes are more rigid when completely dried, but still allow for some squeezing and feel foamy.
