At the rear side of the rack, the upper film feeding device is provided. At the front end of the cutter blade transportation device and on the rack are provided a blade feeding rail and cutter blade carrying device cooperating with each other. At the rear end of the cutter blade transportation device is provided a film sealing device which cooperates with the upper film feeding device and lower film feeding device. At the rear end of the film sealing device and on the rack is provided a dragging device fitting the blade strip. At the back side of the dragging device is provided a transverse cutting device fitting the blade strip. The present invention may achieve automatic feeding by the cutter blade carrying device. The dragging device may extend the upper and lower film material back and forth repeatedly. And the hot-pressing process may be accomplished by the film sealing device. The present invention may automatically seal the blades and the cutting device may separate the product one by one. At last the packaging process may be accomplished with high degree of automation and greatly improve production efficiency.

In a container for packaging filling materials, in particular a bag or pouch made of plastic film, comprising at least one container wall surrounding the filling material, which has at least one front and rear wall, and comprising superposed layers formed in the top region of the container, wherein in the top region of the container predetermined layers are connected over at least one section by means of at least one closure means closing the container, below which a section of the top region located adjacent to the region fitted with the opening has a filling material withdrawal region and that at least one section of a connecting seam is disposed so that it runs around an opening at least in some areas in such a manner that in the top region the multilayer region is separated in a sealing manner from the filling space of the container.

A packing bag to store a stored article Z with tight seal by a welded sheet material 1 of resin in which a separation-prepared line portion 5, separable by predetermined tensile force F by human hands to take out the stored article Z, is provided along an opening-prepared side portion 10, the sheet material 1 has a layered unit construction in which first and second welding resin layers 61A and 61B are disposed on both sides, and a barrier layer 60 is disposed on a middle position, the separation-prepared line portion 5 is composed of a half-cut first laser-worked groove 7A concaved on the first welding resin layer 61A and a half-cut second laser-worked groove 7B concaved on the second welding resin layer 61B, and, the first and second laser-worked grooves 7A and 7B are formed barely damaging the barrier layer 60.

According to an aspect of the invention, provided is a bag-shaped container including a tubular film and at least one pair of engagement portions. The tubular film has an inner surface and an outer surface, and is folded in a manner that the outer surface configures both an inner surface of a bag body and an outer surface of the bag body. The at least one pair of engagement portions projects from the inner surface of the bag body, and engages with each other.

A bag making apparatus includes a welding device for welding a sheet panel and a strip member in a zone where the sheet panel is intermittently fed by a feed device and a cut device disposed downstream of the welding device to cross-cut the sheet panel and the strip member every intermitted feed cycle. The welding device include a pressure unit for pressurizing the sheet panel and the strip member superposed on each other and a laser unit for irradiating the sheet panel or the strip member with a laser beam at an irradiation position upstream of a pressure position of the pressure unit to melt the sheet panel or the strip member. The pressure unit and the laser unit are configured to be movable together upstream and downstream relative to the sheet panel while maintaining a relative positional relationship between the pressure position and the irradiation position.

There is disclosed a bag (101) with a zipper closure and a method for making such a bag. The bag is formed of a first (102) and a second (103) superposed flat side and folded side pieces (104) disposed between the flat sides of the bag and welded to edge areas at the side edges of the flat sides. The bag includes interacting zipper parts (114) in the form of a male part (120) and a female part (119) connected with each their flat side and extending from side edge to side edge. In order to achieve the largest possible opening of the bag, the folded side edges are extending from the bottom edge of the bag to the top edge of the bag. In the side pieces a thinning of material (123) is established in an area next to the areas in the flat sides where the zipper parts are disposed. Thus, the side pieces in the thinned area will have a material thickness enabling the male and female parts to engage each other while at the same time the material of the side pieces is clamped there between.

In an apparatus for successively making plastic bags, a laser beam irradiator irradiates laser beam onto webs of panel material and a body of zipper material to heat and melt the webs of panel material and the body of zipper material with the laser beam. The webs of panel material and the body of zipper material are fed intermittently at a speed predetermined to be changed by time. The irradiator is controlled on a feedforward control basis for the laser beam to be regulated in amount, the amount being calculated from the speed predetermined, to obtain a calculated value of amount. The laser beam is regulated in accordance with the calculated value to heat and melt the webs of panel material and the body of zipper material uniformly irrespective of the speed being changed.

In a packing bag to store a stored article Z with tight seal by a welded sheet material 1, a separation-prepared line portion 5, separable by predetermined tensile force by human hands, is provided, and, the separation-prepared line portion 5 is composed of half-cut laser-worked grooves 7 disposed parallel with a small interval and concaved on an inner face 1a and an outer face 1b.

A pouch includes a bag body, a zipper, and a closing sheet. The bag body includes an accommodation space that can accommodate contents, a first aperture for opening the accommodation space, and a second aperture formed so as not to face the first aperture, for opening the accommodation space. The zipper is attached to the bag body, and unseals and seals the first aperture. The zipper includes a male part and a female part. The closing sheet is attached to the bag body so as to separate the male part and the female part of the zipper from the accommodation space. The closing sheet includes a weakened part that can be broken when unsealing of the zipper.
