Difference between WHA and WMA – Different Compatible Containers

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