  • Publication number: 20050252819
    Abstract: A convenience package for thin film products according to aspects of the present invention places a folded stack of thin film plastic bags inside a container to protect the bags during shipping, handling and dispensing. The container surrounds the plastic bags and includes an opening through which individual bags are retrieved. The plastic bags are attached to each other in such a manner that retrieval of a first bag through the opening in the container partially retrieves a second bag and leaves part of the second bag protruding through the opening. Attachments between bags within the container ensure that each bag is opened as it is retrieved through the opening.
