According to an article on, plant-based bioplastics are already a more eco-friendly alternative to their petroleum-based counterparts. Now, scientists have created a clear bioplastic film that not only blocks harmful ultraviolet radiation, but that is also more airtight than traditional plastics.

Created by a team at Finland's University of Oulu, the transparent "copolymer" film is made entirely of two organic compounds: hydroxymethylfurfural (HMF) and furfural. These are byproducts of the refining of cellulose and hemicellulose – cellulose makes up most of the cell walls of plants, with structurally-simpler hemicellulose also being present in those walls.
