Combination of plastic sheeting for covering an object, such as silage, with at least two layers of sheeting, comprising a first folded sheet and a second folded sheet, wherein the second sheet is folded into said first sheet and wherein said second sheet is at least partially enclosed by said first sheet and wherein the sheets have first and second lateral edges, wherein seen in a cross section, at least the first lateral edges of the two sheets extend in close proximity to each other in the folded combination of sheets.

Folders are disclosed. In some embodiments, the folder may include a unitary planar material folded along a transverse fold forming a front panel and a rear panel. The front panel may be folded over the rear panel along the transverse fold. At least one reference apparatus may be formed with at least one of the front and rear panels. The at least one reference apparatus may be configured to be detached from the at least one of the front and rear panels.

A corner protector is folded from a single sheet of cardboard or similar material along a plurality of lines of weakness. The corner protector includes multiple layers of protection preventing penetration of an apex of the corner protector by a corner received therein.

Folders are disclosed. In some embodiments, the folder may include a unitary planar material folded along a transverse fold forming a front panel and a rear panel. The front panel may be folded over the rear panel along the transverse fold. At least one reference apparatus may be formed with at least one of the front and rear panels. The at least one reference apparatus may be configured to be detached from the at least one of the front and rear panels.

Folders are disclosed. In some embodiments, the folder may include a unitary planar material folded along a transverse fold forming a front panel and a rear panel. The front panel may be folded over the rear panel along the transverse fold. The rear panel may include an additional fold defining first and second portions. One of the front and rear panels may include lateral projections folded along longitudinal folds and affixed to the other of the front and rear panels to form a document receptacle between the front panel and the rear panel. At least one reference apparatus may be formed with at least one of the front and rear panels. The at least one reference apparatus mat be configured to be detached from the at least one of the front and rear panels.

A method of stacking a plurality of absorbent sheet products is provided. In an embodiment, the method includes folding an absorbent sheet inwardly along a first folding line to form a first inner panel, folding the absorbent sheet inwardly along a second folding line, substantially parallel to the first folding line, to form a second inner panel, folding the absorbent sheet along a third folding line substantially perpendicular to the first and the second folding lines to form a first outer panel and a second outer panel, sandwiching the first and the second inner panels therebetween to obtain one of the absorbent sheet products, and inserting at least a section of at least one of the first and the second outer panels of each one of the absorbent sheet products between the first and the second outer panels of an adjacent one of absorbent sheet products of the stack.

A stack of interfolded absorbent sheet products comprising a plurality of absorbent sheets and a method of folding and stacking the same. Each one of the absorbent sheets is folded twice about a first axis to define two inwardly folded inner panels and at least once about a second axis to define at least two outer panels sandwiching the inner panels therebetween. The second axis is substantially perpendicular to the first axis, Each of the absorbent sheet products comprises at least one outer panel at least partially sandwiched between a pair of outer panels of an adjacent one of the absorbent sheet products of the stack. Each one of the absorbent sheet products is entirely detached from all other absorbent sheet products of the stack.

Formable inserts and related methods are disclosed herein. An example of forming a cover with a formable insert includes forming a first frame portion of the cover, attaching a formable insert to the first frame portion of the cover, and forming a second frame portion of the cover subsequent to the formation of the first frame portion to capture a perimeter edge of the formable insert in the second frame portion of the cover.
