Apparatus for manufacturing an open-mouth bag of at least one layer of a flexible bag material, and method of manufacturing a bag by such apparatus. The apparatus includes a shaping device with a shaping box in the contour of the bag shape to be formed, with a top end and a bottom end, a conveying device for transporting the bag material along the shaping box, a closing device for joining the bag material along the shaping box to form a tube, and a closing station for generating a bag bottom, which is disposed beneath the bottom end of the shaping box. A partial vacuum device is configured to generate intermittently, a partial vacuum. When manufacturing a bag, the bag material is draped around the shaping box in the contour of the bag shape to be formed as continuous material and is joined to form a tube by the closing device.

A process for making a container includes the step of providing at least one of a slider, sticker, textured surface, pattern, or embossed surface along a folded web of thermoplastic material that comprises a plurality of container templates. The process also includes the step of picking up, with a turner, each container template. The turner includes one or more rotator assemblies that include a rotatable shaft and a bag-contacting surface connected to an end of the rotatable shaft. The bag-contacting surface is configured to engage a top exterior side of each container template. Additionally, the process includes the step of reorienting, with the turner, each container template. The rotatable shaft is configured to horizontally translate and rotate each container template.

Provided is a pouch container aligned structure, wherein: each pouch container has a folded body part that is the top end of one of a pair of body sheets folded into a substantial V shape, with one end of a top sheet also forming the folded body part by being joined to the top end of the body sheet and the other end of the top sheet forming the distal end portion of the container by being joined to the top end of the other of the pair of body sheets; and the pouch containers are aligned in a state in which the distal end portion of one pouch container is inserted into the folded body part of another pouch container.

A system and process for making a container or pouch that separates the cutting and sealing steps into two distinct steps with a separate step of rotating the container or pouch template 90 degrees relative to a direction of travel between the cutting and sealing steps.

A machine for producing bags includes a station for forming a tube, which forms a band of transversely perforated flexible material into a tube, a holding station for retaining the tube, a folding station for forming a bottom at the end of the tube, a folding roller having a folding blade for folding a flap at the end of the tube and a tear-off bar for pinching the tube against the drum, the folding station and the holding station being configured to jointly exert a traction on the tube and detach a portion of the tube. The tear-off bar is disposed behind the folding blade, the machine controlling the rotation of the folding station to synchronize the drum with the front of the tube.

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 machine for manufacturing flat bottom bags includes a drum for carrying along at least one blank having a flattened tubular shape in an advancing direction, a first scoring apparatus upstream of the drum for marking on the blank a first folding line which is transverse with respect to the advancing direction, a front gripper on the drum that grips a front edge of the blank on the drum, in an opening step, and and carries along the blank, a first lateral gripping means on the drum that grip the lateral edges of the blank in the region of the first folding line.

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.
