Bags are made, with which a stack is formed. To do this, a tube is formed with a strip of flexible material, a portion of tube is separated at the front of the tube forming a first flap at the rear of the portion of tube, the first flap prolonging the first wall of the portion beyond the end of the second wall adjacent to the first wall, a bag is formed with each portion of tube, and a stack of bags is formed, the first wall of the first of the bags being against the second wall of the adjacent second bag. An anti-adhesive coating is applied on to the first wall of the first bag and a coat of adhesive is applied on to the second wall of the second bag ensuring the temporary attachment with the anti-adhesive coating.

An apparatus for making a self-opening bag pack includes a supply of film material. An extruder forms a continuous tube of film. A flattener flattens the tube. A corona treater treats at least one surface of the flattened tube. A first sealer forms a bottom seam across a width of the flattened tube. A cutter cuts the flattened tube into bag blanks at a predetermined distance from the bottom seam. A stacker forms the bag blanks into a bag pack. An adhesion knife penetrates the bag pack and adheres adjacent bag blanks together in the bag pack. An aperture maker forms means for suspending the bag pack from a dispensing rack. The pack is attached to the dispensing rack and the front wall of the subsequent bag will be adhered to the rear wall of a first bag, thereby causing the first bag to open when pulled from the rack.

An apparatus for making a self-opening bag pack includes a supply of flexible film material. An extruder forms a continuous tube of film. A flattener flattens the tube. A first sealer forms a bottom seal across a width of the flattened tube. A cutter cuts the flattened tube into bag blanks has a bag mouth at a predetermined distance from the bottom seal. Second and third sealers form angled seals at lower corners of the bag blank forming a flat bottomed bag. An adhesion knife penetrates the bag pack adhering adjacent bag blanks together in the bag pack. An aperture maker forms apertures for suspending the bag pack from a dispensing rack. The pack is attached to the dispensing rack and the front wall of the subsequent bag is adhered to the rear wall of a first bag, thereby causing the first bag to open when pulled from the rack.

A method for automatically transferring spouted pouches provides a simple, efficient approach for automatically loading spouted pouches from a container to a belt conveyor. And, an automatic pouch transferring assembly is also provided.

A plastic bag comprising two panels and a flap joined to one of the panels and configured for folding over the other of the panels for closure of the bag, wherein at least a portion of the flap has a tackiness which is greater than the tackiness of its associated panel. A stack of bags having a flap with greater tackiness than the tackiness of the major panels of the bags.

A pre-formed bags dispenser comprises a container having an access aperture, a stack of pre-formed bags located in the container and having a first portion (12) deviated, preferably folded, at a transverse bend from a second portion containing mouth ends of the bags, and attachment means in the container separably attached to the mouth ends at lines of weakening, e.g. perforations. Front walls of the bags at the second portion, tensioned by the bending of the stack, are presented towards the access aperture. The bag nearest to the access aperture can be drawn out through the aperture by pulling its front wall, with one hand, relative to the attachment means. As the bag is so pulled its mouth is opened and the separable attachment to the attachment means is released. The attachment means, in one form, comprises a bar block separably joined to the mouths and/or handles of the bags. The container may be in the form of a box substantially closed apart from the access aperture, a tray or a bag.

During the manufacturing process the exterior surface of one or both of the sheets of plastic film which form the bags is treated with low temperature corona discharge plasma to raise the level of surface charge magnitude to at least 43 Dyne to increase the adhesion force between the bags. A recess is formed in each of the bags to further increase the adhesion. The increased adhesion causes the mouth of one bag to automatically open as the adjacent bag is removed from the rack. The recess is formed at the same time openings are created in the bags to accept the support rods of a dispensing rack. The bags can have simple edge sides or side gussets and may be provided in a package including a pouch which receives and supports the lower portions of the bags.

A system including a plurality of disposable bags, a dispenser for the bags and a method of use for accommodating a personal electronic device within each bag to isolate it from the ambient atmosphere is disclosed. Each of the bags includes a pair of panels of a flexible transparent material forming a hollow cavity or pocket having an open mouth through which the personal electronic device may be inserted. Each bag includes a flap for adhesively sealing the mouth of the bag with the device therein so that any pathogens on the device are sealed and isolated within the bag, and pathogens in the ambient atmosphere will not come in direct contact with the personal electronic device. The panels of the bag are frangible so that the bag can be torn open to remove the device, when desired. The dispenser is configured to dispense the bags one at a time.

A protective bag into which a mobile device can be placed to limit exposure of the device to unsanitary conditions or conversely to limit exposure of other surfaces to an unsanitary mobile device. The protective bags are distributed to users using a dispenser. The system improves overall hygiene associated with use of mobile devices.

A film bag (1) with a front film layer (2), a rear film layer (3) and side gussets (4, 5), wherein the front film layer (2) and the rear film layer (3) and the two side gussets (4, 5) are connected together at the lower edge; and wherein the film bag (1) is provided with a set of continuous suspension openings (17, 18), each consisting of four perforation openings, so that the film bag (1) is designed to be suspended on a set of carrier pegs (29); wherein the four perforation openings of each continuous suspension opening (17, 18) are provided as slits, and wherein the front slits in the front film layer are longer than those in the rear film layer, and method for producing a film bag (1).
