The present invention concerns a multi-layer film comprising at least five layers, with two outer layers, two intermediate layers and one core layer, wherein the core layer comprises an ethylene copolymer having a density between 0.910 g/cm3 and 0.925 g/cm3, the intermediate layers comprise an ethylene copolymer comprising 1-octene and having a density between >0.915 g/cm3 and 0.925 g/cm.sup.3, wherein further the first outer layer comprises between 65 wt. % and 93 wt. % of a first ethylene copolymer comprising 1-octene and having a density between >0.915 g/cm3 and 0.925 g/cm.sup.3 and between 7 wt. % and 35 wt. % of a second ethylene copolymer having a density between >0.925 g/cm.sup.3 and 0.945 g/cm3 based on the total weight of polymers of the layer, wherein further the second outer layer comprises between 35 wt. % and 65 wt. % of a first ethylene copolymer comprising 1-octene and having a density between >0.915 g/cm.sup.3 and 0.925 g/cm.sup.3 and between 35 wt. % and 65 wt. % of a second ethylene copolymer having a density between 0.850 g/cm.sup.3 and <0.915 g/cm.sup.3 based on the total weight of the polymers of the layer.

The current disclosure involves the arrangement and efficient deployment of self-adhering flexible sheet material in individual segments to encircle a bale of harvested material and isolate it from the wind, precipitation, and other elements as it remains in the field following the formation of the bale attendant with harvesting of the crop, until collected for further processing. For use with harvested crops such as cotton or hay, the individual wrapping segments further comprise adhering members, which cause a portion of a wrapping segment, generally found at what is considered a trailing end during a wrapping cycle, to releasably attach to adhering members on an opposite surface of the same wrapping segment.

Improved object wrapping materials exhibiting a number of beneficial properties to overcome prior deficiencies are provided. Such properties include the inclusion of a separation interface overlay that allows for greater rigidity at the leading and trailing edges of such wraps. Also, the inclusion of shear-reducing wrap material portions is described, as well as recoil reduction structures within the leading edge regions. Furthermore, core adhesive additions allow for greater resiliency to the base wrap material as it unwinds therefrom, reducing potential waste wrap products by permitting greater amounts of wrap materials in use. Other considerations include the ability, through proper configuration designs, to position a wrap separation indicator within a certain range of distances from the trailing edge, thereby providing greater reliability of wrap application device disengagement during wrap application. Such benefits are thus supplied individually and in tandem for improved versatility and utility of such wrap materials.

In one embodiment, the present disclosure may be a wrapping material for formed bales of materials, including at least one layer of a flexible plastic material film web divided into portions by a plurality of spaced lines of perforations, the web including a first surface and an opposite second surface, each portion having a first adhesive substrate adhered to the first surface of each portion adjacent to each line of perforation, each first adhesive substrate including a first adhesive surface adhered to the first surface of each portion and a second adhesive surface facing outwardly opposite the first adhesive surface, each portion having a second adhesive substrate adhered to the first surface of each portion, each second adhesive substrate including a third adhesive surface adhered to the first surface of each portion and a fourth adhesive surface facing outwardly opposite the third adhesive surface, and a first release liner overlying the second adhesive surface and a second release liner overlying the fourth adhesive surface.

The present disclosure includes various methods of wrapping an item, such as harvested agricultural material, including steps such as unrolling a wrapping material portion from a roll of wrapping material portions, the unrolling starting at a leading end of the wrapping material portion and continuing along a length of the portion towards a trailing end of the portion, each wrapping material portion including a base film, a first adhesive substrate including a bottom adhesive surface attached to a first side of the base film of the wrapping material portion adjacent to the perforation, an outwardly facing first adhesive surface covered by a first release liner with a second adhesive surface facing outwardly and attached to a second side of the base film of the wrapping material portion when on the roll, and further unrolling the wrapping material portion from the roll of wrapping material portions such that the first release liner separates from the first adhesive surface, the first release liner remaining attached to the second side of the base film of the wrapping material portion and the first adhesive surface remaining attached to the first side of the base film of the wrapping material portion. Wrapping material portions may be connected to one another by perforations.

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.

The invention relates to a cover film for fixing material when pressing round bales. The film comprises a copolymer.

A method for storing information corresponding to a baled crop during a baling process includes providing a harvesting machine including a control unit, a sensor, and a bale tag reader. The method also includes forming the baled crop with a bale tag by the harvesting machine, identifying the baled crop by the control unit with a bale identifier, and sensing a characteristic of the baled crop by the sensor. The method further includes detecting a bale tag identifier associated with the bale tag by the bale tag reader, communicating the characteristic and bale tag identifier to the control unit, corresponding the characteristic, bale tag identifier and bale identifier of the baled crop to one another, and storing the characteristic, bale tag identifier and bale identifier in an electronic storage unit that is in electrical communication with the control unit.

In a continuous roll of wrapping material for crops such as cotton or hay, the individual wrapping segments are arranged so that a permanent adhesive is protected until the point when this adhesive is to be exposed for securing a wrapping segment to itself, encircling a subject bale located in and harvested from a field, wherein the contiguous wrapping segments separate from each other either at a point of weakness associated with perforations and the like, or as overlaid segments that slidably come apart.
