Abstract
A sleeve has an open top and side edges. One or more handles are defined by perforations that extend inward from the side edges and can terminate with a stress concentration-reducing shape. The handles may be tapered. The handles may include a reinforcing weld formed by an extension of the bottom seal of adjacent, oppositely oriented sleeves.
