ABSTRACT:
Liquidtight containers which are so integrated at the upper ends thereof as to keep fluids from escaping through the gaps between the front and back walls of the container. The closure system of the bag is designed to surround the upper end of the bag with adhesive when the bag is sealed so that fluid cannot escape between the main part of the bag and the closure. The closure system can also be designed so that an attempt to open the bag and then reseal it will be readily evident.
