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.

A product-containing outer bag in which a plurality of bags that are stacked continuously or intermittently in a row for parts of the bags, which are products, to overlap each other are wrapped with a cylindrical outer bag with a fastener to be integrated while a stacked state of the bags is held. The cylindrical outer bag with the fastener is made of a resin film as a base material and has a cylindrical shape having a uniform inner diameter and continuously extending along a cylinder length direction (X), at least one opening portion to be opened along the cylinder length direction (X), and the fastener on an inner wall side of the base material along an edge of the opening portion, and the fastener is engaged.

In a method for manufacturing a seasoning bag, an edible adhesive is applied to a panel of a bag, and a granular seasoning is applied to the panel of the bag such that the granular seasoning adheres to the edible adhesive pattern to produce a seasoning layer. The granular seasoning forms air channels when the panel of the bag is vacuum sealed against a foodstuff inserted into the seasoning bag, to assist in egress of air from the bag during the vacuum sealing process.

A system for manufacturing bags with counting marks includes a workstation for making bags, and a coding machine for spraying counting marks on the bags. The coding machine includes a main body, a fixing structure and a spraying gun. The main body has ink cartridges for providing ink and a pressure mechanism to spray the ink through the spraying gun. The spraying gun is fixed to a fixing structure and connected to the main body via a cable such that the ink of the ink cartridges is operably moved from the ink cartridge to the spraying gun via the cable. The cable includes channels, each channel adapted for delivering a respective color of the ink. The spraying gun includes nozzles coupled to the channels for spraying the ink on the bags so as to form the counting marks thereon.

In a plastic bag including a triangular flap which has a folded hypotenuse and an open hypotenuse, a flow path is formed by the folded hypotenuse or the open hypotenuse to discharge air or gas through the flow path.

A bag opener is presented as an accessory component for bag roll dispensers, which allows bags to be dispensed to the user in a partially opened state. The opener may be extruded, molded or machined depending on the design of the dispenser, and is suitable for multiple-ply bags (such as star sealed bags) that are dispensed from a continuous roll.)

In a method for manufacturing a seasoning bag, an edible adhesive is applied to a panel of a bag in a pattern of spaced apart lines. A granular seasoning is applied to the panel of the bag such that the granular seasoning adheres to the edible adhesive pattern to produce a seasoning layer having a pattern substantially the same as the edible adhesive pattern.

An exemplary web of preformed bags includes first and second layers, first and second side, first and second side seals proximate the first and second edges, a plurality of transverse seals extending between the first and second side edges, an opening in the first layer, and a line of separation in the second layer, a first line of weakness in the first layer. The first line of weakness has a plurality of gaps having no perforations in a region between the plurality of openings in the first layer and the plurality of traverse seals.

A receptacle-liner dispenser for dispensing disposable liners is provided. The dispenser may include a liner holder including one or more walls. The one or more walls may preferably define an interior configured for storing the liners. The one or more walls may include a dispensing region configured for providing a passageway between the interior and an exterior of the holder. The dispenser may further include one or more tabs projecting exteriorly from the holder. The tabs may be configured to perform a releasable securing of the dispenser to a surface.
