A wrapping material for use with existing wrapping equipment or balers for wrapping bales of agricultural produce or other items are disclosed. The base wrapping material may be a netting, film, or combination thereof. The wrapping material includes a plurality of pre-defined, discrete, spaced-apart adhesive areas disposed on each side of the opposing sides of the wrapping material. The longitudinal spacing of the adhesive areas allows the wrapping material to be rolled onto a roll core so that the discrete spaced-apart adhesive areas contact only non-adhesive areas of the wrapping material thereby forming a first level of adhesion that easily allows the wrapping material to be released and unrolled. When wrapping an item, corresponding discrete adhesive areas come into face-to-face contact thereby forming a second level of adhesion that is stronger than the first level of adhesion.

1. A continuous wrapping material comprising: a plurality of wrapping units, each one of said plurality of wrapping units comprises a predetermined length of base wrapping material that extends in a longitudinal direction and terminates with a leading edge at one end thereof and a trailing edge at an opposing end thereof, said leading edge and said trailing edge both extend said predetermined length in a width direction that is transverse to said longitudinal direction and terminate at opposing lateral edges, said each one of said plurality of wrapping units also includes a first surface and an opposing second surface, said each one of said plurality of wrapping units is serially connected to at least another one of said plurality of wrapping units at least one of the corresponding leading and trailing edges forming a continuous wrapping material;a first plurality of discrete spaced-apart adhesive areas disposed on said first surface of the wrapping unit, wherein each wrapping unit of the plurality of wrapping units includes the first plurality of discrete spaced-apart adhesive areas, and a second plurality of discrete spaced-apart adhesive areas disposed on said second surface of the wrapping unit, wherein each wrapping unit of the plurality of wrapping units includes the second plurality of discrete spaced-apart adhesive areas;for each specific wrapping unit, one of the leading edge or trailing edge of each specific wrapping unit is free of both first and second adhesive areas; andeach of said first plurality of discrete adhesive areas are longitudinally spaced from one another, each of said second plurality of discrete adhesive areas are longitudinally spaced from one another, and said first plurality of discrete adhesive areas is longitudinally spaced from said second plurality of discrete adhesive areas so that when the continuous wrapping material is rolled onto a roll core none of the first plurality of adhesive areas comes into face-to-face contact with any one or more of said second plurality of adhesive areas and when each wrapping unit is wrapped around an item each one of the first plurality of discrete adhesive areas comes into face-to-face contact with a corresponding one of the second plurality of discrete adhesive areas, wherein at least one of said first plurality of adhesive areas adheres to a non-adhesive portion of said second surface of one of said plurality of wrapping units that is not covered by one of said second plurality of adhesive areas when the continuous wrapping material is rolled onto the roll core to ensure that the wrapping material generally remains rolled until use. 2. The wrapping material according to claim 1, wherein each of said first plurality of discrete adhesive areas and each of said second plurality of discrete adhesive areas have a width that is smaller than said width of said base wrapping material, thereby forming a non-adhesive strip at each opposing lateral edge along the length of said continuous wrapping material. 3. The wrapping material according to claim 1, wherein said base wrapping material comprises a netting, a film, a breathable material, or a combination thereof. 4. The wrapping material according to claim 1, wherein said base wrapping material comprises a film. 5. A wrapping material for wrapping agricultural produce into round bales comprising: a continuous base wrapping material having a first surface, an opposing second surface, a thickness, a lateral width, and a longitudinal length sufficient to wrap at least the circumference of an item to be wrapped, said continuous base wrapping material including pre-defined and longitudinally spaced adhesive areas on each of said first surface and said second surface, when the wrapping material is wrapped onto a roll core a first level of adhesion between each of said adhesive areas and a corresponding overlying non-adhesive area of said wrapping material ensures that the wrapping material generally remains rolled until use and allows release of the wrapping material from the roll, and when a portion of said wrapping material is wrapped around agricultural produce a greater level of adhesion is obtained as corresponding adhesive areas are brought into face-to-face contact,wherein said adhesive areas on said first surface are longitudinally spaced from one another and from the adhesive areas on said second surface and the adhesive areas on said second surface are longitudinally spaced from one another and from the adhesive areas on said first surface, such that the continuous bale wrapping material includes a non-adhesive portion of wrapping material in between each adhesive area on said first surface, each adhesive area on said second surface, and between each first surface adhesive area and each second surface adhesive area. 6. The wrapping material according to claim 5, wherein said base wrapping material comprises a netting, a film, a breathable material, or a combination thereof. 7. The wrapping material according to claim 5, wherein said base wrapping material comprises a film. 8. A wrapping material comprising: a base wrapping material having a first surface, an opposing second surface, a thickness, a lateral width, and a longitudinal length;said base wrapping material including at least a first plurality of adhesive areas on said first surface and at least a second plurality of adhesive areas on said second surface, the first plurality of adhesive areas are longitudinally spaced from one another and from the second plurality of adhesive areas, and the second adhesive areas are longitudinally spaced from one another and from the first plurality of adhesive areas, wherein the longitudinal spacing includes a non-adhesive portion of wrapping material in between each adhesive area on said first surface, each adhesive area on said second surface, and in between each first surface adhesive area and each second surface adhesive area, and wherein said first plurality of adhesive areas do not overlap with adjacent second plurality of adhesive areas along the longitudinal length of the base wrapping material when said base wrapping material is rolled onto a roll core; andsaid first plurality of adhesive areas and said second plurality of adhesive areas each has a width that is smaller than said width of said base wrapping material, thereby forming a non-adhesive area along the length of said base wrapping material,wherein at least one of said first plurality of adhesive areas adheres to the base wrapping material when the base wrapping material is rolled onto the roll core to ensure that the wrapping material generally remains rolled until use. 9. The wrapping material according to claim 1, wherein each specific wrapping unit is free of both first and second adhesive areas along a leading section commencing from the leading edge.
