Method and apparatus pertaining to a flexible wrapping material having laser-formed crease lines
One or more lasers ( 80, 100 ) form one or more crease lines ( 140, 150, 151 ) in a flexible wrapping material ( 60 ). The flexible wrapping material is then folded about the one or more crease lines when encapsulating an item to be wrapped within the flexible wrapping material. The flexible wrapping material may have poor dead-fold characteristics and can comprise a flow-wrapping material. A single laser or multiple lasers can serve to form the one or more crease lines. The crease lines can be formed on a same side of the flexible wrapping material or on both sides thereof. By one approach, folding the flexible wrapping material about the one or more crease lines forms, at least in part, a form-factor conformal pocket to accommodate the aforementioned item. By another approach, folding the flexible wrapping material about the one or more crease lines forms, at least in part, a gusset.
1. An apparatus comprising:
a wrapper configured to be disposed about a solid item, wherein the wrapper comprises a flexible wrapping material that exhibits poor dead-fold characteristics in that it exhibits a percentage spring-back of greater than 50%; and
a plurality of laser-formed crease lines in the flexible wrapping material, the laser formed crease lines being configured such that when the flexible wrapping material is folded about the crease lines when the item is wrapped in the wrapper a form-factor conformal pocket is, at least in part, formed to accommodate the item, and wherein the laser-formed crease lines include two opposing arcuate laser-formed crease lines formed on a same side of the flexible wrapping material, each of the arcuate crease lines having opposing ends that are each connected to an end of a corresponding straight laser-formed crease line that extends at a right angle and all the way to an edge of the flexible wrapping material.
2. The apparatus of claim 1 wherein the opposing ends of each of the arcuate crease lines also connect to an end of a corresponding laser-formed crease line that extends away from the corresponding arcuate crease line such that the crease lines and folded material forms the form-factor conformal pocket to accommodate the item and visually suggest concave side surfaces of the item.
3. The apparatus of claim 1 wherein the flexible wrapping material exhibits poor dead-fold characteristics in that it exhibits a percentage spring-back of greater than 75%.
