An automatic packaging apparatus is provided, having a conveyor, a continuous longitudinally folded web, cutting and sealing mechanisms for forming flexible pouches from the web. The apparatus also includes processing stations for loading the pouches, transferring fluids (typically gases) into and out of the pouches, and sealing the pouches. Various alternative methods and devices are provided for separating each sealed pouch from the web by either making a continuous cut across a connecting strip of web material downline of the processing stations or pre-perforating the connecting strip upline of the processing stations. When the connecting strip is pre-perforated, a sealed pouch of sufficient weight may be separated from the web passively by a takeaway conveyor, and a lighter sealed pouch may be separated from the web by a tear-off mechanism that grips and pulls the web.

An exemplary web of preformed bags includes first and second layers, first and second side, first and second side seals proximate the first and second edges, a plurality of transverse seals extending between the first and second side edges, an opening in the first layer, and a line of separation in the second layer, and first and second cuts in the first and second side seals. The first and second cuts are configured to reduce or eliminate a breaking force necessary to break the first and second side seals when the web is torn along the line of separation.

A method of making a web of multi-dose cleaning products may include forming first and second pluralities of internal holders in a first film, forming a first plurality of external holders in a carrier sheet corresponding with the first plurality of internal holders, and forming a second plurality of external holders in the carrier sheet corresponding with the second plurality of internal holders. The method may also include filling each of the first plurality of internal holders with a first cleaning composition, and filling each of the second plurality of internal holders with a second cleaning composition. Furthermore, the method may include sealing a second film to the first film to define first and second pluralities of pouches, folding the carrier sheet so that each of the first plurality of pouches overlaps a corresponding one of the second plurality of pouches, and sealing together overlapping portions of the carrier sheet.

A pre-packaged paint sample includes a sealed package, paint sealed within the package, and a new paint applicator sealed within the sealed package. For use, the package is shook to apply the paint to the paint applicator. The sealed package is opened, and the paint applicator is removed from the package. The paint applicator and used to apply the relatively small amount of the paint t. The pre-packaged paint sample can be useful in applications where only a small amount of paint is needed such as, for example but not limited to, paint sampling, paint touch up, and the like.

The paper recyclable heat sealable bag includes a heat sealable water soluble inner layer coating and an article of paper. The heat sealable coating is applied to the article of paper by a printing press. As the printing press applies the heat sealable coating to the article of paper, the paper recyclable heat sealable bag may be wound into a master roll with a plurality of paper recyclable heat sealable bags. The master roll is fed into an automatic packaging system which fills the bags with a product from at least one of a top edge and a side edge of the paper recyclable heat sealable bags. The paper recyclable heat sealable bag has certain perforations to remove the paper recyclable heat sealable bag more easily from the master roll and sealed with a heat sealer.

A gas-sealed bag is formed by two outer films and two inner films. The gas-sealed bag includes a first transversal heat-seal line, a heat-resistant area, a second transversal heat-seal line, gas inlets, and longitudinal heat-seal lines. The second transversal heat-seal line includes protrusions and bottoms. The protrusions are in the heat-resistant area, and the bottoms are out of the heat-resistant area. The transversal heat-seal lines form an inflation channel, and one end of the inflation channel includes an inflation port. The gas inlets are formed at positions coating a heat-resistant material and corresponding to the protrusions. A gas storage chamber is formed between each two adjacent longitudinal heat-seal lines. Accordingly, additional heat-seal nodes are not necessary to be provided on outer sides of the inner films and inner sides of the outer films for facilitating the inflation port to open. Therefore, manufacturing steps for the gas-sealed bag can be reduced.

The present disclosure relates to a method for producing an oral pouched snuff product comprising a filling material (29, 10) and a saliva-permeable pouch (43) enclosing the filling material (29, 10), the product (29, 10) having a moisture content of at most 20% by weight, in particular at most 10% by weight, based on total weight of the product (29, 10), the saliva-permeable pouch (43) having one or more seals (45, 46), and said filling material (29, 10) comprising at least 20% by weight, based on dry weight of the filling material (29, 10), of at least one ingredient having a melting temperature below 180 C., the method comprising ultrasonically welding and cutting an advancing web (32) of packaging material (7) to which the filling material (29, 10) has been supplied. The present disclosure also provides an oral pouched snuff product which is obtainable by this method.
