Abstract
There is described a contact lens package containing a bowl for holding a contact lens and a flange around the bowl which may be made from a different polymer material than the bowl. The packages comprise at least one interface tab with at least one slot so that the second polymer material forming the flange can encapsulate the tab providing a mechanical interlock displaying good flexural strength.
