China will become the latest country to outlaw ultra-thin plastic bags, when a ban takes effect on Sunday, in a bid to cut pollution and save resources. The ban, announced by the State Council in January, halts the production of bags that are thinner than 0.025 mm and forbids their use in supermarkets and shops. It also requires retailers to charge customers for thicker plastic bags not covered by the ban. Environmentalists say plastic bags can take up to 1,000 years to disintegrate and pose threats to marine life, birds and other animals.
