Prime Minister Theresa May will tell the G7 summit that plastic pollution in the oceans is a "global problem, requiring global solutions".
As part of World Oceans Day the new zones will protect rare or threatened marine habitats and species including the short-snouted seahorse, eider ducks, stalked jellyfish and peacock's tail seaweed.
No new activities deemed damaging - such as dredging, or significant coastal or offshore development - will be allowed, while existing harmful activities will be minimised or stopped.
The 41 proposed new MCZs follow the 50 already announced as part of the Blue Belt programme.
The new zones cover approximately 11,700 square kilometres, bringing the total area of protection to over 32,000 square kilometres.
