ABSTRACT:
Reclosable bags having a slider-actuated string zipper and tamper-evident features. In one aspect, the bag comprises: a receptacle having a mouth and an interior volume; a string zipper installed in the mouth; a slider mounted to the string zipper; a membrane depending within the interior volume to block access to a portion of the interior volume when the string zipper is open; and a hood joined to the receptacle and shrouding the mouth. The membrane is made by forming a gusset. Then a string zipper is installed inside of the gusset and heat sealed in place. Later a hood or shroud is attached to the bag walls at an elevation traversed by the gusset panels. A layer of non-sealable material is applied on a surface of a gusset panel to prevent the gusset panels from being sealed together when the hood is heat sealed to the bag walls.
