Abstract: The present invention is directed to a produce bag. More specifically, the present invention is directed to a completely recyclable and compostable grocery-type bag for use with produce and other goods. Ideally, the bag is a calendared single-ply paper with heat-sealed seams that is resistant to destruction from moisture. While produce is contemplated, the bag can be used to contain virtually any product. Preferably, such a bag would have a window or an opening so that produce can be viewed and readily identified. The present invention is further directed to a process for creating and filling the above bag. Using a standard printing machine, the adhesive is printed onto the paper in register to desired locations on the paper to form the seams of the bag and, optionally border a window area to be cut out of the paper.

Abstract: A composite netting is used for wrapping bales with a baling machine. The composite netting includes a continuous netting component, and a discontinuous, breathable material component. The breathable material component is partially attached to the netting material. In some embodiments, the breathable material is attached only along the leading edge of each breathable material panel. As a result of the attaching technique the stretching properties of the netting are not transferred to the breathable material. Thus, each component of the netting retains its individual properties. Each bale is initially wrapped with about one wrapping of netting material, followed by about one wrapping of breathable material and a partially attached net that is continuous from the first section. After this, one or more additional netting layers may be applied if desired.
