Scientists have created an ultraviolet blocking bioplastics that is more leakproof than traditional plastics. This is stated in a study by scientists from the University of Oulu, published in the journal Macromolecules and Biomacromolecules.
The transparent “copolymer” film created by the researchers consists of two organic compounds: hydroxymethylfurfural (HMF) and furfural. These are by-products of refining cellulose and hemicellulose. By chemically bonding HMF and furfural, the researchers were able to combine the structural qualities of both substances.
The resulting bioplastics blocks most of the incoming ultraviolet rays. In addition, it is three to four times hermetic than standard polyethylene terephthalate polyethylene film. This means that in the future, the new bioplastics can be used as packaging for food and can protect them from the harmful effects of sunlight, while keeping them fresh.
Bioplastics is completely decomposed in the soil in a few months, and oil products and fossil fuels are not used for its production, the authors note.
