A filling slit is formed in a first panel of web material of a flexible pouch enclosure formed from the first panel and an opposing second panel of the web material and having a resealable closing assembly having interlocking male and female members joined to a flange. After the flexible pouch enclosure is at least partially filled with a product through an opening in the first panel of the web material that is created by the filling slit, the filling slit is closed by sealing the first panel to the flange of the resealable closing assembly.

A tissue paper package not prone to losing shape. Film-packaged tissue paper comprising a pop-up type substantially cuboid bundle of tissue paper packaged with a flexible resin packaging film, and characterized in that air vents for providing communication between the inside and the outside of the package are formed at positions on the packaging film facing short-side surfaces of the bundle of tissue paper where no folded edges are arranged.

A method and apparatus for forming pouches and/or bags is disclosed. A seal and/or insert is crushed using a multiphase sealer or crusher.

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.

A flexible pouch has an internal zipper adding support to the pouch and allowing the contents of the pouch to be portioned. Flexible pouches having a product disposed therein are also disclosed, along with kits containing same. In addition, methods of producing the flexible pouches and packaged products are also disclosed.

According to one embodiment a packaging method is provided in which a tube is supplied in a forward movement direction. The method includes a folding step in which the tube is acted on in a manner that is transverse to the forward movement direction, folding part of the tube in a folding direction, and a sealing and cutting step after which a tube closed at one end and a package closed and separated from the tube are obtained. During the folding step the tube is held transversely, and a tear is generated in the folding direction between the acted on and held parts of the tube. The tube is sealed on both sides of the tear and cut at the height of the tear. Packaging machines for carrying out the method are also disclosed. Suitable.

A vertical flow-wrapper with a form-fill-tube along which a film is transported in a transport direction and formed into a tube, a longitudinal-sealing means, which seals two opposing longitudinal ends of the formed film together to a longitudinal seal, and a cross-sealing means and a cutting means which provide cross seals to each package and separate the packages from each other and means to apply re-closure means to each package, arranged parallel to the longitudinal seal and as individual segments.

Recyclable pouches formed from rollstock and having a resealable closure that extends into both side edges of the pouch may be produced at high speeds on a single manufacturing line in which the pouches are formed, cut apart, filled, and then sealed if the film forming the pouch comprises a recyclable heat seal layer and a second recyclable layer having a melting temperature of at least 30° C. greater than the heat seal layer.

A light-absorbing layer and a bonding layer are layered on a first side of each of a belt-shaped male base portion integrated with a male portion and a female base portion integrated with a female portion on a side of the male and female base portions opposite the first side. The light-absorbing layer contains a light-absorbing material having a wavelength absorption range from 800 nm to 1200 nm to absorb a laser beam of the range. The bonding layer contains a low-melting-point resin in a form of a metallocene linear low-density polyethylene having a melting point ranging from 60 degrees C. to 120 degrees C. When the zipper tape is bonded to the base film, the laser beam is applied to heat the light-absorbing layer to melt the bonding layer. The melted bonding layer is pressure-bonded to the base film. The base film can be bonded without causing thermal degradation.

A system for applying a fastening material to a substrate is provided. The system may include a first material source including the substrate. The substrate may define a first length extending from a first edge to a second edge and the first material source may feed the substrate in a first direction transverse to the first length. The system may additionally include a second material source including the fastening material. The fastening material may define a second length extending from a third edge to a fourth edge, whereby the second length is substantially equal to the first length and the second material source feeds the fastening material in a second direction transverse to the second length. The system may also include an applicator system that secures the fastening material to the substrate.
