摘要： A roll of separable bags which leaves no scrap material and method of making a roll of separable bags which leaves no scrap material is disclosed herein. An elongated tube of material having a length and a width is laid flat, forming a web of material. The web of material comprises an outer and an inner sheet portion. First and second seals are formed widthwise across the outer and inner sheet portions. First and second bag separating perforation lines are formed widthwise across the outer and inner sheet portions. A user may tear one bag away from the roll of bags by using the bag separating perforation line. The user may then deploy the handles of the bag by tearing along the handle perforation lines.

摘要： A web of preformed bags includes a sheet material and a cushioning material. The sheet material includes two sheets that are arranged to form a series of bags. The sheets are connected together to form sides of each of the bags. Each of the bags is bounded by an opening and the sides where sheets are connected together. The cushioning material is coupled to inner surfaces of the sheets in each of the bags. The web further includes a line of weakness in at least one of the sheets between each of the bags. After an object is loaded in one of the bags, the opening of the one of the bags is configured to be sealed closed with the object therein such that the cushioning material in the one of the bags is arranged to cushion the object when the one of the bags is sealed closed.

摘要： 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.

摘要： A trifold side seamed film produce bag includes a front wall and a back wall, first and second side edges sealed together and a seamless bag bottom. The bag is joined at the side edges to additional bags by a perforation. The bag is corona treated on at least one wall and promotional material is printed on the treated surface. The bags are folded to one third of their height to fit compact bag roll dispensers. The bags are folded in a Z-fold or C-fold configuration. The method includes manufacturing the bags and winding them onto cores or forming the bags into coreless rolls. An apparatus for forming the side seamed bags includes an extruder, a tubing flattener, a perforator, a sealer, a corona treater, a printer and a slitter. The treated, printed bags may be stored on rolls for later slitting into two bag streams and folding into thirds.

摘要： A plastic food bag includes a first plastic foil and a second plastic foil. The first foil and the second foil are disposed adjacent to one another and are continuously merged together at three edges to form the plastic food bag. The first foil contains a printable area. The printable area includes at least one of a cover layer and a middle layer that includes a thermosensitive material that changes color when heated, or, alternatively, a printing layer. The printable area is printable after the forming of the plastic food bag.

摘要： Biodegradable bags for disposing of a unwanted substance are formed from a bioplastic material made from a bio based material in the form of a maize flour, and a biodegradable plasticizer selected from the group consisting of vegetable oil, polyesters made from glycerin, glycerin, derivatives of glycerin, and combinations thereof. The maize flour comprises a minor volume percent of the total volume of the bioplastic material. A biodegradable additive is used to provide a degree of stiffness to the material, a preferred additive being polylactic acid. A UV stabilizer may optionally be included. Biodegradable bags have an open end and a closed end with a sidewall extending therebetween. The bag includes a feature for enclosing a substance once placed into the bag. In an example, the feature comprises an opening through a sidewall. Alternatively, the feature may include an adhesive section.
