Container and lid with multiple seals therebetween and methods for making and using the same

A moisture tight container comprising:

• a container body having a base and a sidewall extending therefrom, the body defining an interior configured for housing product, the body having an opening leading to the interior, an outer rim projecting radially outward from the sidewall and encircling the container body near the opening, the outer rim having a planar body rim surface;
• and
• a lid having a lid base, a skirt depending therefrom, and an lid outer rim extending from the skirt, the lid outer rim having a planar lid rim surface, a hinge pivotally attaches the lid to the container body such that the lid is movable with respect to the container body between a closed position in which the lid covers the opening so as to create a moisture tight seal with the body and an open position in which the opening is exposed, when the lid is in the closed position the lid rim surface faces the body rim surface, the moisture tight seal comprising an elastomer seal disposed on the body rim surface,
• wherein, when the lid is in the closed position, the moisture tight seal comprises an elastomeric-to-thermoplastic seal created by the elastomer seal engaging and being compressed by the lid rim surface.

• wherein the moisture tight seal further includes a thermoplastic-to-thermoplastic seal created by mating a body undercut surface of the body with a lid undercut surface of the lid,
• wherein the container, when the lid is in the closed position, has a moisture vapor transmission rate (MVTR) of less than 400 μg/day at 30° C. and 80% RH.
