Closure profile for packaging bags has opposing profiles with closure ribs to retain end of bag and marked rib to show if profiles are open

摘要

The closure profile for packaging bags has two closure profiles (10,20) with complementary ribs (12,14,22,24) to open and close and retain the inserted bag ends. The end rib (18) on one profile has an undulating edge (19) to visually discriminate the closure profile and a support flange (26). The edge rib can have a colored surface.
