A former provides an insert at the lip of the former to enable packaging material to travel smoothly over the former. The insert lays smoothly on the top surface of the former. The insert is sized approximately one half the width of the packaging material that travels over the insert. The former provides a raised textured surface that enables the packaging material to travel over the former into the aperture. The insert constructed with a smooth top surface is located adjacent at least a portion of the aperture. The insert provides a smooth surface for the packaging material to travel across when entering the aperture.

The present invention relates to a method and to a system for calibrating an automatic pouch forming machine.

The present invention also relates to a device for characterizing a pouch precursor made of flexible heat-sealable film, said device comprising: a punch; a heat source for heating at least a tip of the punch to a given temperature; an actuator for pressing the punch against the pouch precursor made of heat-sealable film, with a given pressure; a measurement device for measuring the penetration of the punch in the pouch precursor, under the given conditions of temperature and pressure.

A pinch bottom sack fillable with bulk good includes a sleeve with at least one area element, wherein the sleeve includes a mesh and the area element a handle means including a load element at which a load force is applicable for lifting the sack, and the load element is configured such that it extends at least in some areas at least in a load condition in which the load force acts at the load element opposite to an outer side of the area element.

A method for manufacturing a pouch-type packaging material includes: a first folding process; a first cutting process of cutting the top-side sheet material, a second sub-region, a first main region, and a first sub-region along a first cutting line that extends from a portion where the top-side sheet material and the second sub-region overlap to a portion closer toward a bottom side in a z direction beyond a first boundary line; a second folding process; a second cutting process of cutting the top-side sheet material, the first sub-region, the first main region, and a second main region along a second cutting line to form a top-side sheet from the top-side sheet material, where the second cutting line extends from a portion where the top-side sheet material and the first sub-region overlap to a portion closer toward the bottom side in the z direction beyond the second boundary line.

Bags for containing various retail items, such as food items, and methods of forming the same. In some aspects, a bag having a top and bottom is provided. The bags can include a first layer and a second layer opposite the first layer and uniformly extending from the first layer. In some aspects, the bag can further include a first side seam between a side of the first layer and an opposing side of the second layer and a second side seam between a side of the second layer and an opposing side of the second layer. The first layer and the second layer each have an un-folded edge substantially parallel to the bottom fold. In some aspects, the bags include a bottom V-shaped fold extending along a transverse axis relative to the first side seam and the second side seam, the bottom V-shaped fold forming a seamless bottom.

Embodiments of the present disclosure describe a method and apparatus for a resealable package having an internal zipper seal. In one embodiment, the apparatus is a vertical form, fill, and seal machine that includes a former, a vertical sealer, and a zipper separation blade located between the former and the vertical sealer. The zipper separation blade further comprises a connector and a blade body that defines a zipper gap between an exterior surface of the former and the blade body.

An automatic packaging machine including a folding assembly of a continuous sheet of packaging material, in particular paper, having a sliding plane for conveying the continuous sheet of packaging material along a conveying direction is disclosed. The sliding plane includes an entrance end for entering the continuous sheet of paper and two opposite sides parallel to the conveying direction. Further, the folding assembly includes a feeding assembly for feeding the continuous sheet of packaging material along a feeding plane which is substantially orthogonal to the conveying direction and defined at the entrance end of the sliding plane. The folding assembly further includes a block associated with at least one of the opposite sides of the sliding plane and a body associated with the block and provided with a cone-sector surface which supports a longitudinal flap during longitudinal creasing and accompanies it during the folding along the longitudinal creasing.

The invention relates to a method for producing a bag, in which method a bag is produced from a fiber material, preferably a paper material, wherein a web made of the fiber material, preferably a paper web, is unwound as a flat web, thereafter sequential adhesive strips are applied in continuous operation, thereafter the flat web is folded to form a bag shape, thereafter the adhesive strips are activated, for connection, by the application of heat, and thereafter individual bags are cut from the flat web by means of a cutting device.

A woven plastic bag is made by longitudinally feeding flat-lying fabric web having a layer of woven-together plastic strips on a first face, opposite longitudinal edge regions spaced transversely from each other and each extending over about 10% of a transverse width of the fabric web, and a middle section between the longitudinal edge regions. A pattern is applied the first face of the fabric web in a pattern that repeats along the production direction only locally with a coating in the form of a film or in the form of a liquid plastic of a width or shape that varies transversely, and the fabric web is shaped into a fabric tube. In order to form individual woven plastic bags, the fabric tube is cut transversely into pieces of the fabric tube suitable for subsequent filling and sealing.

The present invention relates to a tubular bag machine for producing tubular bag packaging materials from paper, comprising a draw-off station (2) for drawing off a paper web (10), a roughening station (3) for the continuous roughening of at least one joining region of the paper web (10), a moistening station (4) for moistening at least one joining region of the paper web (10), a forming station (5) for forming a bag tube, and an ultrasonic sealing station (6) for sealing the joining region of the paper web (10).
