US 10,239,278 B2 · Wrapping material and method of manufacture for baling materials

Abstract

A wrapping material for formed bales of material. The wrapping material including at least one layer of a flexible plastic material film web having a substantially uniform width and divided lengthwise into portions of substantially equal length by a plurality of spaced lines of perforations extending fully transversely across the width of the wrapping material and fully through the layer or layers forming the wrapping material. Each said line of perforations having a first adhesive substrate adhered to a first surface of said wrapping material adjacent to but spaced from the line of perforations. The first adhesive substrate extending substantially across the width of said wrapping material and having, in use, an outwardly facing adhesive surface, and a second adhesive substrate extending substantially across the width of said wrapping material and being adhesively secured to said first surface of the wrapping material whereby the second adhesive substrate overlies said line of perforations.

Dependent claims

A method of manufacturing a roll of connected multiple individual portions of wrapping material for wrapping formed bales with a said individual portion of said wrapping material, said method comprising the steps of:

providing a base web of a flexible plastic material film having at least one layer;
forming a plurality of substantially evenly spaced lines of perforations extending fully transversely across and fully through said base web;
applying a first adhesive substrate to a first surface of said base web adjacent to but spaced from each said line of perforations, said first adhesive substrate having an outwardly facing first adhesive surface covered by a first release liner with a second adhesive surface facing outwardly;
applying a second adhesive substrate to said first surface of said base web adjacent to said first adhesive substrate and overlying said line of perforations, said second adhesive substrate having a second release liner covering an outwardly facing adhesive surface of said second adhesive substrate;
and
rolling said base web into a said roll whereby the second adhesive surface of said first release liner adheres to a second surface of said base web.
