What needs to be investigated is: how to add colours for example. Get rid of the green, make it white or another colour (for eastetic reasons). Besides that, the thickness of this new form of packaging material needs to be Investigated, so heavy products or food can be packaged also.
Maybe it is to be redesigned, add another natural product, so it hardens. Note: seaweed is now investigated to replace human tissue. With succes: scientists remove the green parts, so only the tissue remains. Its implanted in human and takes over the human tissue system. Maybe there's an effective collaboration possible.
Anyway: if this kind of package is dumped into the water, rivers, or oceans, no harm done! The ' package ' is then where it belongs!
