Abstract
Abstract A web of wrapping material in the form of a constant width sheet of synthetic plastic film having parallel bands of metal foil secured along opposite side edges is longitudinally folded, prior to winding into a supply roll, about an offcenter fold region in the film so that the fold region is at one end of the roll and the foil bands lie in laterally spaced non-overlapping relation at the other end of the roll, thus providing a short roll requiring a shorter container and facilitating clean severance of a leading end length wound off the roll.

Claims Analysis
Total Claims: 5
Claim 1
Independent Claim
130 words
A package comprising a relatively wide web of laminated wrapping material wound in a roll and consisting essentially of a substantially constant width sheet of thim flexible synthetic plastic film having relatively narrow bands of metal foil surface bonded along its opposite side edges, said film being folded upon itself longitudinally about an offcenter region so that said metal foil bands are disposed in adjacent laterally spaced nonoverlapping relation nearer one end of the roll than the other, and said folded web at said offcenter region having a thickness of substantially only twice that of said film and the folded portions overlying in free contact whereby random lengths of the folded web material may be severed and unfolded to provide a full width laminated wrap at the time of use.
Claim 2
Dependent Claim
130 words
A package comprising a relatively wide web of laminated wrapping material wound in a roll and consisting essentially of a substantially constant width sheet of thim flexible synthetic plastic film having relatively narrow bands of metal foil surface bonded along its opposite side edges, said film being folded upon itself longitudinally about an offcenter region so that said metal foil bands are disposed in adjacent laterally spaced nonoverlapping relation nearer one end of the roll than the other, and said folded web at said offcenter region having a thickness of substantially only twice that of said film and the folded portions overlying in free contact whereby random lengths of the folded web material may be severed and unfolded to provide a full width laminated wrap at the time of use.
Claim 3
Dependent Claim
33 words
The package defined in claim 1, wherein said fold region is disposed at one end of said roll and said laterally spaced bands are both disposed adjacent the other end of said roll.
Claim 4
Dependent Claim
27 words
The package defined in claim 1, wherein said folded web has at no point a thickness greater than twice the film thickness plus one thickness of foil.
Claim 5
Dependent Claim
