Researchers at the Georgia Institute of Technology have published a research report saying that new environmentally friendly films made from crab shells and trees are expected to replace widely used food wrap products.
The new film is flexible, transparent, degradable and meets high air tightness. It is undoubtedly another technological innovation to solve the problem of plastic waste pollution.
With the continuous improvement of the technical level, in order to solve the “white pollution” caused by plastic waste, many new materials and new processes have begun to appear.
For example, new materials that can be completely dissolved in water, as described by engineers in Santiago, Chile. Their experiments modified the chemical formula of PVA (polyvinyl alcohol) to obtain a new alternative to plastic products, without oil derivatives.
A large Japanese paper manufacturer also disclosed a specially processed wrapper to replace everyday plastic packaging. It is understood that this kind of wrapping paper has certain waterproofness and good sealing performance.
The concept of bioplastics is not new, but large-scale promotion is limited by many conditions. Recently, a report published by Swiss scientists said that bottle-grade polyethylene furan ester (bioplastics) production time is only 30 minutes, the performance is comparable to traditional plastic.
These latest news have greatly boosted the confidence of plastic pollution control, and at least the technical breakthrough has been made in the replacement of easily degradable plastics. Of course, in a short period of time, the full coverage of environmentally friendly plastic products cannot be achieved, and a multi-pronged layout is also necessary.
