A method of forming reinforced packages. The method can comprise moving a blank in a machine direction on a blank conveyor, and forming a tubular web while moving a first web of material and a second web of material in the machine direction. The forming the tubular web can comprise at least partially sealing at least a portion of the first web and the second web together to form a sealed margin of the tubular web. The method further can comprise forming a liner by cutting the tubular web, forming an attached blank by attaching the liner to the blank, and moving the attached blank in the machine direction on the blank conveyor.

According to some illustrative embodiments, a protective product is provided that includes: an envelope having a two-layer wall structure, the two-layer wall structure including a) a first outer paper layer, and b) a second inner paper layer, wherein the second inner paper layer includes width-wise positional variations of the side surface of the second inner sheet that cushions items placed within an inner pouch of the envelope, and forms an interior wall of the inner pouch of the envelope and directly contacts the items placed within the inner pouch of the envelope. In some preferred implementations, the width-wise positional variations of the side surface of the second inner paper layer includes pleats, undulations and/or embossments, and, preferably, the pleats, undulations and/or embossments include ridges that extend perpendicular or substantially perpendicular to an outlet of the envelope.

According to some illustrative embodiments, a system and method is provided that includes, e.g., means for continuously conveying an assembly of layered sheets including a first paper sheet, at least one expanded sheet and a second paper sheet in a conveying flow between, e.g., a rotary mandrel or member at an upstream position in a direction of conveyance and a rotary die crushing and cutting tool, with said rotary mandrel or member and said rotary die crushing and cutting tool maintaining the at least one expanded sheet in an expanded state, said rotary tool having a crushing component that crushes a portion of the at least one expanded sheet such as to form a flap forming region of an envelope and a cutting component that cuts the assembly of layered sheets such as to separate individual envelope units.

The present disclosure relates to strata 2-ply drawstring trash bags implementing a J-flap extended hem to provide increased top-of-bag strength. In one or more embodiments, the J-flap extended hem includes a 2-ply web folded back on itself (e.g., during a hem folding operation to enclose the drawstring within a hem channel). In one or more implementations, a hem seal secures the 2-ply web to an inside surface of the trash bag. At least one ply of the 2 -ply web fold-over extends past the hem seal and is additionally secured to the inside surface of the trash bag via one or more hem skirt seals. For reduced material consumption in certain embodiments, the J-flap extended hem of the present disclosure imparts added strength using only one ply of the 2-ply web fold-over. In some embodiments, at least one ply of the 2-ply web fold-over includes ring-rolled portions to add top-of-bag strength.

The invention is a hybrid inserter/wrapper system comprising a hybrid inserter/wrapper system comprising a modular document inserter system and a unique wrapper-like envelope creation module operably connected thereto. The wrapper-like envelope creation module is configured to operate in a first mode and a second mode. In the first mode, the wrapper-like envelope creation module is configured to fabricate wrapper-like outer envelopes and feed such outer envelopes to the inserter system. In the second mode, the wrapper-like envelope creation module is configured to allow the inserter to be loaded with premade envelopes and feed such envelopes to the inserter system. In either mode, the document inserter system further carries out downstream operations to thereby produce a finished mailpiece.

An automatic packaging bag production device is provided. The automatic packaging bag production device includes an easy-tear line forming mechanism, a sealing and cutting mechanism, a tray, and a traction mechanism, where the easy-tear line forming mechanism includes a first passage and is configured to form an easy-tear line on a belt-shaped material passing through the first passage; the sealing and cutting mechanism includes a second base plate, and a cutting assembly and a sealing assembly arranged on the second base plate; the cutting assembly includes an upper cutter and a lower cutter that are movable close to or away from each other and a second passage is formed between the upper cutter and the lower cutter; the sealing assembly includes an upper sealer and a lower sealer, and a third passage is formed between the upper sealer and the lower sealer.

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.

The product efficiency of bags each with an end face part is increased. A panel webs is guided to be divided along a line of weakness of the panel web and to be folded along division edges of the panel web. This guiding of the first panel and temporary sealed sections cause a side gusset to be cut open along a line of weakness of the side gusset such that open surfaces are formed. After the forming of the open surfaces, an end face web is supplied to be superposed on folded parts of the panel web and the open surfaces of the side gusset.
