The resins, which is being marketed under the trade name Gaialene, are produced by grafting polyolefins onto modified starches. According to Roquette's website, the resins has over 50% bio-based content; are designed for durable and semi-durable uses; but are not biodegradable - with mechanical properties similar to polyethylene and polypropylene.
Some of their beneficial properties include low density, low melting temperature, silken/leather-like texture, and natural antistatic properties. Gailene is said to be compatible with in-house recycling processes - alone or with polyolefins; reusable as new after recycling; and can be easily separated from conventional plastics in the production stream.
The resin is processable by extrusion blowing, injection or extrusion blow-molding.
