A method of producing flexible polypropylene fabric bags with heat fused seams comprising providing fabric pieces, wherein each fabric piece has a coated side and an uncoated side; positioning fabric pieces so that a coated side of one fabric piece faces a coated side of another fabric piece; selecting an area of fabric to be joined for forming a seam or joint; applying heat to the area to be joined that is less than the melting point of the fabrics, for forming one or more seams or joints and wherein the heat fused seams or joints of a resulting polypropylene bag retains at least 85% of the fabric strength without using sewing machines.

A woven laminated plastic bag having an easy open feature is provided. The easy open feature is generally defined by a weakened portion in the bag. In various aspects the bag can be fabricated from woven polypropylene and/or polyethylene layer which can be laminated with a film layer, can form a pinch bottom bag, and can have one or both sides include graphics and/or printing. The bag can also provide a top end and/or a bottom end either or both of which provide a discrete area which may contain discrete graphics and/or printing.

Methods of producing a bag for a feed product involve providing a multi-layered substrate, which includes one or more polymers. The method also involves extruding a polymer film onto a surface of the substrate to form an elongated sheet. The polymer film can include a mold inhibitor. The method further involves slicing the elongated sheet into smaller, individual sheets and joining pairs of the individual sheets together along a periphery thereof to form the bag configured to receive the feed product. The polymer film can line the inner surface of the finished bag.

A cotton-based single use grocery bag for carrying groceries or other items. The single use grocery bag is also used for cleaning furniture, cleaning counter tops, washing dishes, etc. The single-use grocery bag may include the a body made of a cotton gauze material defining an internal compartment between a first side, a second side, a third side, a fourth side, a top, and a bottom, wherein the internal compartment is accessed through an opening at the top; the first side and the third side each comprise edges coupled together at a bottom portion of the body and separated at a top portion of the body; and the separated edges define a gap communicating the internal compartment with an outside of the body, wherein each gap is entirely disposed downward relative to the top and the opening and communicates the internal compartment to the external environment.

An equipment containment and transport assembly (20) includes an open-top equipment-receiving primary bag (22) having upstanding sidewall structure (26) equipped with lifting lug opening pairs (30, 32), and a bottom wall (28). The assembly (20) further has a flexible sleeve (24), which is secured to the sidewall structure (26) and is shiftable between a ready position surrounding the sidewall structure (26) and a deployed position extending upwardly for closure or the assembly (20). When deployed, the sleeve (24) covers the lug opening pairs (30, 32). The assembly (20) is particularly useful for containment and shipping of electrical transformers.

An apparatus for shipping or storage of Li-ion batteries comprises a sealable outer bag fabricated from heat-resistant, permeable fabric, a first flexible thermal runaway shield (TRS) fabricated from low-permeability film configured to line a first inside surface of the outer bag, a second flexible TRS fabricated from low-permeability film configured to line a second inside surface of the outer bag, and at least one Li-ion battery configured to be disposed between the first flexible TRS and the second TRS of the sealable outer bag to provide a sealed outer bag.

An apparatus for a thermal runaway shield enclosure for Li-ion batteries is disclosed. The apparatus comprises a thermal runaway shield (TRS) case having rigid walls with openings on at least one side of the case, and a heat-resistant, permeable fabric configured to line interior walls of the TRS case, wherein at least one Li-ion battery is placed inside the TRS case.
