Abstract
An improved method for packaging utilizes the two-spaced clippers for simultaneously attaching the first and second U-shaped metal clips to gathered packaging material. Prior to attachment of the clips, the tail end of the packaging material is wrapped around a movable sleeve or post which is extended to effect tight packing of the contents of packaging material. The movable post is then released after attachment of the clips. With the invention, it is possible to form a loop or handle using the same material that is used for packaging of a product. Additionally, the construction and method reduces the likelihood of the operator developing carpal tunnel syndrome.
