ABSTRACT:
There is provided a thermoplastic film bag having at least two integral members that facilitate opening the bag. The bag is manufactured from a flattened tube of thermoplastic material which may be distinctively severed along independent phase shifted sinusoidal oscillating paths down the center of the collapsed tube. The bag may have two opposed tie members which are offset from the vertical center axis of the bag and from each other. The tie members may be grasped and pulled apart to facilitate the easy opening of the bag. The tie members may then be tied together to form a strong member by which the bag may be picked up and carried. In alternate embodiments the shape of the integral tie members can be modified to create a bag having only the easy open feature with no tie members. A method for making the bag is also described.
