Plastic plastic,as the name suggests,is a plastic raw material,which is very convebient to process.Taking plastic bags as an example,it is a process called film blowing similar to blowing bubbles.The thickness can be dozens of microns,which is equivalent to the diament of a hair,but it can withstand several kilograms of vegetables and fruits.Not to mention the low cost ones are less than a few cents.It's hard to find something so useful and cheap at this level.
Solving the problem of white pollution caused by plastic mainly depends on garbage classification and recycling.In fact,plastic is a reusable material.Most plastics can be heated and melted and remade into new objects.In addition,there are many plastics that are degradable,such as polylactic acid plastics,but the main problem now is that these are too expensive,so they have not caught on.
