A web of bags includes a sheet material and a connecting material. The sheet material includes two sheets that are formed from a fiber-based material, are arranged to form a series of bags, and are connected together to form sides of the bags. Each bag is bounded by the sides where sheets are connected together and an opening. The connecting material is applied to inner surfaces of the sheets and can be activated to connect inner surfaces by the activated portions of the connecting material. The connecting material is applied to closing regions on the inner surfaces of the sheets such that the connecting material in the closing regions can be activated to close the opening.

A resealable bag includes a first end, a second end, a first transverse seal sealing the first end and a second transverse seal sealing the second end. The second transverse seal is part of a weak seal zone of the bag that can be readily unsealed by a consumer by hand. The bag further includes a third transverse seal between the first transverse seal and the second transverse seal, closer to the second transverse seal than the first transverse seal. The third transverse seal is at least partially longitudinally aligned with the second transverse seal and can be selectively unsealed and resealed by the consumer by hand. In one embodiment, a fourth transverse seal is located between the first transverse seal and the second transverse seal, while being at least partially transversely aligned with the third transverse seal, and part of a strong seal zone of the bag.

The paper recyclable heat sealable bag includes a heat sealable water soluble inner layer coating and an article of paper. The heat sealable coating is applied to the article of paper by a printing press. As the printing press applies the heat sealable coating to the article of paper, the paper recyclable heat sealable bag may be wound into a master roll with a plurality of paper recyclable heat sealable bags. The master roll is fed into an automatic packaging system which fills the bags with a product from at least one of a top edge and a side edge of the paper recyclable heat sealable bags. The paper recyclable heat sealable bag has certain perforations to remove the paper recyclable heat sealable bag more easily from the master roll and sealed with a heat sealer.

A multi-layer film and a film package made from the film are described herein that provide resealing capabilities by utilizing a tacky layer within the multi-layer film. The multi-layer film can include an outer film portion including the embedded tacky layer and an inner film portion. An opening feature formed in the multi-layer film includes a flap configured to be manipulated by a user to create an opening through the multi-layer film. The inner film portion can include a release layer configured specifically to interact with the tacky layer to provide a desired separation peel force and resealing functionalities. The outer film portion can include an outer film layer disposed on an opposite side of the tacky layer from the release layer that is configured to permanently adhere to the tacky layer.

The invention is directed to a polymeric film web, a carrier film, and a magnetic member. The carrier film comprises an inner polyethylene terephthalate layer and an outer plastomer layer. The magnetic member and the carrier film are layered onto the polymeric film web to form a closure member. The outer plastomer layer is adjacent the magnetic member and the carrier film extends beyond an upper edge and/or a lower edge of the magnetic member. The closure is heat sealed such that the seal at the interface of the first carrier film and the second carrier film is a peelable seal, the seal at the interface of the first film web and the first carrier film is a permanent seal, and the seal at the interface of the second film web and the second carrier film is a permanent seal.

A packaging bag with contents (1), the packaging bag with contents (1) being formed by filling a pillow packaging bag (10) with a fluid material and sealing the pillow packaging bag (10), wherein: a lateral seal (22) disposed on an upper end of the pillow packaging bag (10) has a projecting portion (23) and a retreated portion (24) formed in a stepped state; a back seal (21) disposed on a rear surface of the pillow packaging bag (10) is coupled only to the retreated portion (24); and the projecting portion (23) is cut off in the lateral direction so that the fluid material (5) is pushed out. The back seal (21) is folded onto the retreated portion (24). A cutting-off notch (26) is provided on an inner edge portion connecting the projecting portion (23) and the retreated portion (24).

The third transverse seal is at least partially longitudinally aligned with the second transverse seal and can be selectively unsealed and resealed by the consumer by hand.

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. If the bag is to include a window opening, the window opening is cut out within the area of applied heat-activated adhesive and a screen cover to the window such that the border of the screen cover is applied to overlap the heat-activated adhesive. Optionally, a recyclable and compostable patch can be placed around the window such that the patch covers the edge of the screen and the heat-activated adhesive to form a border for the window. The patch and screen cover to the window, if present, are adhesively sealed to the paper by heat activation. One method of assembling the bag includes forming the adhesive applied paper to create a tube of paper such that the heat-activated adhesive overlaps the paper, heat sealing the paper into a tube, automatedly filling the tube with product, heat sealing the bottom edge and top edge of the product-filled tube to form an enclosed bag with product therein. The forming and filling can be accomplished on already existing automated forming and filling machines manufactured for use with plastic bags and plastic lined paper bags. Thusly creating a sealed, filled paper bag that is a single ply unlined paper with a mesh covering attached to the paper without the need for reinforcement that can withstand the moisture released from the contents and is 100% recyclable and compostable.

One or more embodiments of the present disclosure relate to a pouch for packaging fermented foods, a method of packaging fermented foods using the same, and a pouch for packaging.
