A protective product, such as, e.g., an envelope or pouch, is provided that includes at least one expanded slit paper sheet in an expanded state, and an embossed paper sheet facing the expanded slit paper sheet and fixed to the expanded slit paper sheet along at least a portion of a length in an expansion direction of the expanded slit sheet paper. In the preferred embodiments, the embossed paper sheet has a plurality of embossings that increase the rigidity of the embossed paper sheet, thereby inhibiting deformation of the embossed paper sheet that is fixed to the expanded slit sheet paper.

According to some illustrative embodiments, a protective product is provided that includes: at least one expandable slit paper sheet, said at least on expandable slit paper being expanded between opposing ends of said slit paper; a first embossed paper sheet facing said expanded slit paper sheet and a second paper sheet facing an opposite side of said at least one expanded slit paper sheet, at least one of said first embossed paper sheet and said second paper sheet being fixed to said expanded slit paper sheet at the opposing ends of said expanded slit paper sheet and thereby maintaining said expanded paper in its expanded state, said first embossed paper sheet having a plurality of embossings that increase the rigidity of said embossed paper sheet, whereby inhibiting deformation of said embossed paper sheet that is fixed to said expanded slit sheet paper.

A bag processing apparatus includes: a defect detection unit which detects occurrence of a defect in processing of a bag; and an imaging unit which is separately provided from the defect detection unit and takes images of a location creating a cause of occurrence of the defect to acquires video data, the vide data being stored in association with the occurrence of the defect.

A thermoplastic bag includes raised rib-like elements that allow the thermoplastic bag to expand. The thermoplastic bag further includes side seals having rib-like elements that allow the side seals to expand. Additionally, in one or more implementations, the thermoplastic bag includes one or more of a material formulation, a density of raised rib-like elements, a height of raised rib-like elements, or land areas that provide the raised rib-like elements with a reduced rebound ratio.

In the preferred embodiments, the embossed paper sheet has a plurality of embossings that increase the rigidity of the embossed paper sheet, thereby inhibiting deformation of the embossed paper sheet that is fixed to the expanded slit sheet paper.

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.

A method and apparatus for making bags or pouches is disclosed. It includes a track, at least two sleds that move on the track, and operating stations mounted on the sleds. The film moves along the track, and the sleds move with the film while performing operations on the film. The system can have the sleds stationary while operating for an intermittent machine, and move to reconfigure when the film is moving. The operating stations include one or more of a sealer, a heater, a cooler, an inserter, a knife, a punch, a perforator, a static charger, and a printer. The track forms a continuous path or is linear. A controller controls the sleds and operating stations. The controller includes an operating time and/or a reconfiguration module. The operating time module is responsive to a user set material thickness or a sensed material thickness.

In a printing method, is obtained position information of an invisible region invisible from outside, out of the printing surface of the packaging base material. Then a flushing process in which ink is ejected the ink toward the invisible region from the nozzle based on the position information is performed. Therefore, printing for packaging pouch can be satisfactorily performed on the packaging base material without impairing the design quality of the packaging pouch manufactured by applying the bag making process to the packaging base material.

The invention relates to a system and a method for manufacturing a medical package, in particular a foil bag made of plastic. A print image with variable information is first applied by means of a thermal transfer printer which is formed as a negative print image and comprises blank spaces. The blank spaces are filled by means of a hot stamp printing process.
