The bag (100) has an inner pocket (302) inserted in an outer pocket (106), where the pockets are made of paper. The pockets respectively comprise gusset forming walls (112, 308) arranged opposite to each other. A handle (118) is formed by cutting slits (120, 122) at mid-length of the gusset forming wall of the outer pocket. The gusset forming wall of the outer pocket has a plane wall folded along a median line extending over length of the plane wall. The slits are formed on both sides of the median line. Each slit has curved shape comprising loops (124, 126) directed opposite the median line.
