An embodiment of the invention disclosed herein comprises a plastic bag construction having tie portions formed as an integral part of the bag which are used to close the top of the bag when filled. The bag is formed of a flattened flexible plastic tube having front and back panels and folded in portions extending along the side edges of the panels. A weld is formed along the bottom edges of the panels to close the bag and a weld is formed along the top edges of the panels to hold together the front and back panel portions which form the tie portions. A struck out portion is formed through the front and back panels near the top edges thereof and the material between the struck out portion and the top edges of the panels will form the integral tie portions. |
