Abstract
A blister package for a contact lens is provided that includes a body and a seal, one or both of which is made up of a double layer foil component. The double layer foil component can be a seal component made of a sheet of material folded upon itself and defining a seal, a flap, and a fold. The seal and the flap intersect at the fold and the flap can be pulled away from the seal to form a pull tab useful to peel back the seal and open the bowl. The body can also, or instead, be made of a double layer foil component that forms at least the bowl such that the bottom of the bowl is double-walled. The double-walled bowl exhibits improved strength and can be provided with strengthening features such as ribs, ridges, channels, or grooves.
