Pallet Hood Tear Tape

Abstract

A packaging system for products on a pallet or slipsheet has a shrink hood or stretch hood with a tear tape for easy opening at the product use location without damaging the product. The tear tape may be a shearing tear tape to allow for cutting through the tough film of the hood or the tear tape may be aligned with laser perforations to cooperate with the tear tape.

Description

BACKGROUND OF THE INVENTION[0001]1. Field of the Invention[0002]The present invention relates to tear tapes on shrink hoods and stretch hoods for products on a pallet.[0003]2. Description of the Related Art[0004]Tear strips comprising a thin thread or string of fiber placed within the container at its top are shown in U.S. Pat. No. 3,543,343 to Staller, as a means to open sealed containers along a single tear line. The drawback of such tear strips is that the tear line may deviate from the top of the bag and propagate into other container elements and compromise its strength, shape and operation. U.S. Pat. No. 3,827,427 to Uramoto defines two tear lines, one on each lip of a bag mouth, between pairs of ribs to contain the propagating tear. In U.S. Pat. No. 5,022,530 to Zieke, a tear strip comprised of a bead of thermoplastic material is provided to define a tear line generally along the top edge of the flexible container.[0005]Tear strips are typically comprise weakened lines for te...

[0024]In accordance with the above objects and those that will be mentioned and will become apparent below, another aspect of the present invention comprises package shipment system comprising a base comprising a pallet or slipsheet; one or more products supported by the base; a hood fitting over the one or more products comprising a containment selected from the group consisting of a shrink hood or a stretch hood; wherein the hood comprises a tear tape for tearing the hood and the tear tape is attached to the interior of the hood and covers a line of laser perforations.

Problems solved by technology

The drawback of such tear strips is that the tear line may deviate from the top of the bag and propagate into other container elements and compromise its strength, shape and operation.

This can cause inadvertent product damage.

However, these perforations could lead to weakening the stretch hood or to product damage during the perforation step.

Although a variety on tear tape technologies have been applied to individual containers and small combinations of containers, tear tapes have not been applied to shrink hoods or stretch hoods.
