Abstract

Abstract A packaging assembly wherein a protective liner is affixed to the interior surface of a flexible bag in a manner such that the packaging assembly folds flat for storage and transport and is readily converted to a substantially rectangular box for loading. The flexible bag extends beyond the top of the liner in a manner such that evacuation and controller atmosphere packaging techniques may be readily applied and the packaging assembly readily sealed. The packaging assembly is especially suited to prevent puncturing of the packaging by either the internal contents or from external sources and provides labor efficient packaging techniques.
