Abstract

A re-closable packaging assembly includes a container formed at least partially by a first film, and the container has a plurality of walls that cooperate to define an interior volume. The container has an opening through at least one of the plurality of walls. A closure assembly is secured to the container adjacent the opening and comprises a second film and a portion of the first film. The closure assembly includes a lid member pivotable about a hinge portion between a first position in which the lid member releasably engages the container surrounding the opening and a second position in which the lid member is pivoted away from the opening. A first engagement feature may be disposed on the container and a second engagement feature may be disposed on the lid member to removably secure the lid member to the container when the lid member is in the first position.
