Paper or plastic.?

From today's Nation:

Nairobi City Council (NCC) announced yesterday that it will implement the by-laws gazetted on July 6, 2007 that state no person shall sell, import, manufacture, produce, or store non-biodegradable polythene carry bags of less thickness than 30 microns in Nairobi. Anyone found carrying thin plastic paper bags could face up to six months in jail once the ban is in force.

File under 'I'll believe it when I see it'. But note also the reference to "plastic paper bags." In Kenya, both plastic and paper shopping bags are called 'paper bags.' It can be a bit confusing when someone refers to the "paper bag" they're carrying, when it's clearly made of plastic. Fortunately I don't think I've ever been to an establishment that offers a choice between the two.
