The present invention relates to improvements for reclosable polymeric bags. Disclosed is a polymeric film bag with film made from a blown film extrusion or a cast extrusion process. The bag is formed from a continuous multi-layer web of polymeric film. The bag comprises burn through side seals formed by a rotary drum that forms the sides of the bag and severs the film of the multi-layer film to form individual bags. Interlocking zipper stock is provided to the web and affixed to an upper end of the bag by an adhesive. Further disclosed is a high-speed continuous process and system for manufacturing the reclosable bags.

A method for manufacturing a protector for a portable electronic device includes following steps. A substrate having a first surface, a second surface and an edge is provided. A first sheet having a first sheet surface and an edge portion is provided, wherein the first sheet surface includes a first hot-melt adhesive. The first surface of the substrate is caused to contact the first sheet surface, wherein the edge portion protrudes the edge. The edge portion is folded along the edge to enable the first hot-melt adhesive to contact the second surface of the substrate. A second sheet having a second sheet surface including a second hot-melt adhesive is provided. The second surface of the substrate and the edge portion is caused to contact the second sheet surface. A thermocompression bonding is performed to bond the first sheet, the second sheet and the substrate together.

A system and method of at least partially forming reinforced packages. The method comprises moving a web of material in a downstream direction through a web forming section, at least partially forming at least a bag portion in the web of material during the moving the web of material through the web forming section, forming an attached web by adhering a construct to the bag portion of the web of material, and moving the attached web through a separating station. The moving the attached web can comprise moving the construct with the web of material. The method further can comprise separating the bag portion from a remainder of the web of material to form a bag during the moving the attached web through the separating station, the bag being attached to the construct.

A paper/plastic-film carrier bag, includes: a cylindrical receiving portion, which is configured to receive an approximately cubic-shaped article; and a long-shaped handgrip portion, being formed extending from one of upper sides of said cylindrical receiving portion, on a side of which is in contact any one of sides of the approximately cubic-shaped article, and reaching to another upper side of the cylindrical receiving portion facing thereto. And a method for manufacturing the above, in particular, the plastic-film carrier bag, comprises the following steps of: a step of producing a fully-closed sack by conducting a welding process on a cylindrical plastic film progressing in an in-line process, for sealing a portion to be a side surface of the plastic-film carrier bag and separating from; a step of removing an unnecessary portion from one or plural pieces of said fully-closed sack(s) being piled up.

A tool holder includes a foldable plastic sheet being folded and configured to include a hanging end and a holding end. The hanging end and the holding end integrally form a one piece structure. The holding end having a first edge, a second edge, a first lateral edge, and a second lateral edge, with the first and second edges and the first and second lateral edges delimiting a circumferential periphery of a receiving space in which the first and second edges are opposite each other and the first and second lateral edges are opposite each other and respectively extend from two lateral sides of the first edge to two lateral sides of the second edge. A joint edge is distal the first lateral edge extending therefrom and adhered to the second lateral edge.

A station (S) of application of segments of opening/closing strip on plastic web films suitable to form bags, comprising punching means (U14, U22) of predefined areas of the plastic film for the access to areas of the segments through the film, and welding means (U15, U23) of the strip segments at intervals on the plastic film, wherein the punching means (U14, U22) and the welding means (U15, U23) are positioned along the flow path of the film to act in sequence on the same area in order to, respectively, punch the film and weld the segments in the predetermined points of the plastic film. In particular, the station (S) comprises two operating units (U1, U11; U2, U21), suitable to cooperate from opposite sides with the plastic film, each of which provided with the punching means (U14, U22) and the welding means (U15, U23), angularly staggered with respect to the punching means (U14, U22), and operatively connected with translation means (U31) that move at least one of the operating units (U1, U11; U2, U21) to bring them closer and separated, allowing the execution of the punching of the plastic film by the punching means (U14, U22) and the welding of the strip segment in the punched area of the plastic film, and with motorization means (U12, U21) that rotate the operating units (U1, U11; U2, U21) around longitudinal axes for selectively and alternately arranging the welding means (U15, U23) and the punching means (U14, U22) facing to the plastic film.

A heat sealing method of a zipper tape is for heat sealing the zipper tape in a direction perpendicular to a feeding direction of a film. The heat sealing method includes: inserting the zipper tape between the film and a circumference of a roller on which the film is wound; and heat sealing the zipper tape to the film with a seal bar following a rotation of the roller in a continuous manner, while the zipper tape is interposed between the circumference of the roller and the film.
