Difference between WHB and WMB – Different Compatible Containers
While WHB and WMB have the same functionality, they are compatible with different containers due to differences in their shapes. WHB is suitable for containers with an overlapping lid (ST), while WMB is suitable for containers with a catch clip closure (CTH). It is not recommended for containers with a lever band closure (CTL).
