Abstract
Disclosed is a biodegradable oriented film of a plasticizer-containing biodegradable resin, of which the both surfaces are coated with at least one thin layer and of which the loop stiffness change (ΔR) after heat treatment at 130° C. for 30 minutes is at most 20%. This is favorable for wrapping films.
