It's been almost three years since China banned plastic bags from supermarket and produce markets. Since then, what used to such a natural and free part of bagging shopping has required additional charge. According to the National Development and Reform Commission, supermarkets have reduced their plastic bag use by two-thirds since the ban took effect. But cheap or even poisonous ultra-thin plastic bags are still widespread in farmer’s markets. It was reported that China will update plastic bag ban and ban restaurants and hospitals from handing out free plastic bags.
