You can use single use plastic bag 50 times or more before it deteriorates, not the thinnest kind, but the average one. They are incredibly strong. The dedicated mult-use ones are insanely strong, but also few times thicker and more unwieldy.

Like with single use shaving razor. They don't need to be literally single use. It depends on the user. You can use it as long as it serves you.

The best thing limiting access to plastic bags did was familiarizing people with the idea of taking bags to the market.

Just a note: Razors are single use for health reasons - not reusing razor significantly reduces chances of inflammation.

If this is really true, why does Gillette advertise their high-end, multi-blade razors as multi-use? For their top product, they say "up to 20 comfortable shaves".

		Sure, as you can also reuse single use razors. But the main benefit of single use is reducing the chances of skin inflammation after using the razor. If using single-use razors, I'd recommend replacing just the blades, not the razor.
