A continuous roll of wrapping material for crops such as baled cotton wherein wrapping segments are set off by spaced transverse lines of slits or scoring for predictable separation during the wrapping process. Protection of the transverse lines and sealing assistance may be included by the addition of an adhesive layer and a V-fold over the transverse lines.

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.

A bale wrapping system that includes a belt that rotates to form and drive rotation of a bale of an agricultural product. The bale is configured to be wrapped with a wrapping layer of a bale wrap while rotating on the belt. A first portion of the wrapping layer overlaps a second portion of the wrapping layer while disposed on the belt. A glue system sprays a layer of glue onto the wrapping layer. The layer of glue enables the first portion of the wrapping layer to couple to the second portion of the wrapping layer.

Disclosed in embodiments herein are monolayer or multilayer films. The films include at least one layer including a) a polyethylene polymer component comprising linear low density polyethylene; and b) a wax component comprising nonpolar, polyethylene wax, wherein the nonpolar, polyethylene wax has a density of 0.955 grams/cm.sup.3 or greater, and wherein the nonpolar, polyethylene wax is present in an amount of at least 3 percent by weight of the film. Also disclosed in embodiments herein are related compositions and methods of making monolayer or multilayer films.

A prestretched polyethylene film having a longitudinal degree of pre-stretching above 70% and a remaining longitudinal elongation capability of at least 300% as determined according to ASTM D882, wherein said film is a coextruded blown film comprising at least one core layer arranged between two exterior layers, wherein the thickness of the film is in the range of 10-30 m, and wherein the film comprises at least 25% by weight of a linear low density polyethylene (LLDPE) substantially free from long chain branching (LCB) produced using a Ziegler Natta catalyst and hexene, heptene or octene as comonomer and having a density of between 910 and 915 kg/m.sup.3. Use of the prestretched polyethylene film as an agricultural balewrap film or silage film, pallet wrapping film, or waste wrap film.

A wrapping device for wrapping a bale with a wrapping material for a baler includes a separating device having a knife arrangement and a blocking device. The separating device is movable between at least one wrapping means separating position and an inactive position. The blocking device prevents the separating device from being moved into the wrapping means separating position.

An enveloping material for enveloping a bale formed by a baler includes a piece of material disposed and wound on a supply roll. The material is configured to being fed to the baler on the supply roll. The enveloping material defines a longitudinal dimension and is subdivided along its longitudinal dimension into a plurality of separable portions.

An enveloping device for enveloping a bale with an enveloping material for a baler includes a supply of the enveloping material. The supply is configured to feed the enveloping material to a pressing chamber of the baler through a feed gap. A braking device is provided for the enveloping material. The braking device is configured such that it has an effect that the enveloping material assumes an at least substantially predetermined position with respect to the pressing chamber of the baler to at least one working means of the baler or to the bale at either an end or a start of an enveloping operation.

An enveloping material for a baler for enveloping a lateral surface of a bale includes a piece of material having at least one entrainer.

A system and method for automatic wrapping bales in a bale wrapper, including placing a bale on a loading table and performing a wrapping cycle. The wrapping cycle including rotating a wrapping hoop to apply a wrapping material to a bale surface, moving a bale pushing device from a first position toward a second position to push the bale through the wrapping hoop, dispensing from a first material applicator and a second material applicator, determining presence of the wrapping material, by a sensor on the wrapping hoop, adjusting based on the determining, a ratio of moving speed to rotational speed of the wrapping hoop, to apply a predetermined amount of wrapping material independent of the presence of wrapping material dispensing, continuing to move the bale pushing device until the second position is reached, stopping the rotation of the wrapping hoop, and moving the bale pushing device to the first position.
