Definitions

  • the present invention relates to a flow-wrap pack for wipes and tissues, in particular, wet wipes, dry wipes and dry tissues.
  • Flow wrap packs are widely used for packaging various products, e.g. food products such as chocolate, biscuits, cakes, but also for household, hygiene or technical products.
  • Typical household products are wet wipes which are small moistened pieces of paper or cloth.
  • Further products are dry wipes and dry tissues. Wipes and tissue are typically used for cleaning purposes.
  • Flow-wrap packs comprise a film in the form of a monolayer film or a multilayer film.
  • the flow-wrap packs may also comprise further structures such as reclosable plastic closures or resealable labels.
  • the structure of the laminate depends on the properties desired with respect to the packaged product, e.g. in terms of a barrier effect against oxygen, moisture or light from outside of the pack but also from inside of the pack, e.g. to prevent drying out of the packed products.
  • Films used for flow-wrap packaging are usually produced and delivered to the packer in form of webs. In the course of the packaging the film is unrolled and wrapped around the product. Usually, the packaging process is done on horizontal or vertical flow wrapper machines.
  • a resealable label applied over the die cut opening allows reclosing the pack after the item has been removed.
  • Another possibility for a removal system is the integration of a plastic closure that allows reclosing the flow-wrap pack after removing a single item.
  • the additional parts of the flow-wrap pack i.e. the resealable label or the plastic closure, require additional steps in the packaging process rendering it more laborious and complicated.
  • the printed resealable label does not match the graphics and colours printed on the front wall of the flow-wrap pack due to different printing processes for the flow-wrap pack and the label.
  • the object of the present invention is to provide a flow-wrap pack having a simple removal system providing for an easy opening and reclosing of the flow-wrap pack without the need for additional parts complicating the packaging process.
  • a flow-wrap pack for wipes and tissues has a film.
  • Said film defines a front wall, a back wall, a longitudinal sealed seam in the form of fin seal arranged on the back wall and two transverse sealed seams defining a product space.
  • the fin seal is formed by two longitudinal sealing strips arranged on a side of the film facing the product space. The two longitudinal sealing strips extend parallel to the side edges of the film adjacent to a non-sealing end region arranged on the same side of the film, whereby the sealing strips are peelable and resealable.
  • Peelability is defined as the ability to separate two film materials in the course of opening a package without compromising the integrity of either of the two.
  • the film of the wrap pack is folded or wrapped around the product to be packed in a way that the sealing strips of the film mate on the back side of the pack and are sealed in order to form the longitudinal sealed seam.
  • the flow-wrap pack is closed by the two transverse sealed seams.
  • the flow-wrap pack according to the present invention provides a removal system for the packed products that is easy to operate.
  • the non-sealing end regions are easily separated and serve as a handle to peel off the sealing strips that form the fin seal which closes the flow-wrap pack on the back wall. Thereby an opening is provided which allows removing of a single item. After removing the item the sealing strips are pressed to one another and folded back down against the back wall in order to reseal the flow-wrap pack.
  • the die cut and the resealable label applied over the die cut can be omitted and do not compromise the print on the front wall through differing colours which are due to different printing processes used for the flow-wrap pack and the label.
  • the packing speed is significantly increased.
  • the film used for manufacturing flow wrap packs preferably comprises at least two different polymers, e.g. polyethylene and polypropylene.
  • the polymers are arranged in different layers of the film.
  • an outer side of the film i.e., the side forming the outside of the pack
  • an inner side of the film i.e., the one facing the product space
  • the transverse sealed seam is achieved by sealing the outer side of the film.
  • Such a transverse sealed seam facilitates a tighter pack and provides a pinch effect in the area of the fin seal, giving the possibility to separate interleaved wipes during removal of wipes from the flow wrap pack.
  • the fin seal on the back wall as well as the two transverse sealed seams are achieved by sealing the inner side of the film.
  • the sealing strips have a width in the range of 2mm to 20mm, preferably in the range of 5mm to 15mm, most preferably in the range of 8mm to 12mm.
  • the non-sealing end-region has a width in the range of 15mm to 40mm, preferably in the range of 20mm to 30mm.
  • the non-sealing end-region is important for convenient handling of the pack. If the non-sealing end-region does not have a minimal width it gets difficult to grip the end-regions by hand and open the flow wrap pack.
  • a print layer is arranged on at least on a part of the front wall.
  • a protective layer is arranged on top of the print layer.
  • the print layer may also be arranged on the whole front wall.
  • a print layer may also be arranged on a part or on the whole back wall.
  • a protective layer is arranged on the print layer of the back wall.
  • the longitudinal sealed seam in the form of fin seal formed by the two longitudinal sealing strips comprises a pressure sensitive adhesive.
  • Further types of adhesives that can be used are fracture hotmelt, cold seal lacquers, heat seal lacquers and glue dots. Pressure sensitive adhesives are preferred.
  • the film of the flow-wrap pack may be a multilayer film.
  • the film is monolayer film.
  • Materials used for the film are polymers comprising polyolefin, polyester, polyethylene, polypropylene, polyamide and metalized plastics, or silicon oxide (SiOx, whereby 1.3 ⁇ x ⁇ 1.9).
  • Ethylene-vinylalcohol copolymer (EVOH) is a further polymer that can be used.
  • oPET/PE oPET/PE
  • oPP/oPET/PE oPET/oPP/PE
  • oPET/oPET/PE oPET/oPET/cPP
  • oPP/propylene oriented polypropylene
  • oPET oriented polyethylene terephtalate
  • PE polyethylene
  • cPP cast polypropylene
  • the following film structures are preferred: oPP/PE, oPP/cPP, PET/PE, PET/cPP.
  • the film structure oPP/PE is most preferred.
  • the above mentioned polymers may also be coextruded to form a monoweb comprising different resin layers.
  • a method for the production of the flow wrap pack is as follows: In a first step the different layers of the film are printed and subsequently laminated. The resealable strip and the tear line are arranged on the film. The tear line is preferably achieved by laser scoring. It may also be done by mechanical scoring. Then the film is slit to size into reels which are delivered to the packer of the flow wrapped product. The packer produces the final flow wrap pack employing the film in flow wrap pack machines.
  • Fig. 1 shows a flow-wrap pack from the prior art.
  • the flow-wrap pack 1 has film 3. Further, the front wall 5 and the two transverse sealed seams 11 are shown. The longitudinal sealed seam on the back wall cannot be seen.
  • An adhesive label 19 is arranged on the front wall 5 in order to cover the die cut opening used for the removal of the product.
  • Fig. 2 shows and end view of a flow-wrap pack 1 according to the present invention.
  • the flow-wrap pack 1 has a film 3 defining a front wall 5 and a back wall 7. Only one of the two transverse sealed seams 11 which close the pack on its longitudinal ends can be seen.
  • the front wall 5 does not comprise any opening system for the removal of the product and may therefore carry a print which is not compromised by further adhesive labels.
  • the longitudinal sealed seam 9 is arranged on the back wall 7, preferably in the middle of the back wall 7.
  • the longitudinal sealed seam 9 has the form of a fin seal which is shown in an upright position.
  • the non-sealing end regions 13 next to the side edges 17 of the film 3 are easily separated and provide for an easy opening of the flow-wrap pack.
  • Fig. 3 shows a plain view of a back wall of the flow-wrap pack 1.
  • the flow-wrap pack 1 is in a closed state.
  • the longitudinal sealed seam 9 in the form of a fin seal and the non-sealing end regions 13 lie essentially flat against the back wall 7 defined by the film 3.
  • the two transverse sealed seams 11 close the flow-wrap pack 1 on either end in its longitudinal direction.
  • Fig. 4 shows a film used for flow-wrap packs 1 according to the present invention.
  • the side of the film 3 which is shown is the side that faces the product space in the finished flow-wrap pack.
  • the sealing strips 15 run in the longitudinal direction of the film, thus extending parallel to the side edges 17. Further, the sealing strips 15 are arranged adjacent to the non-sealing end regions 13 that are delimited by the side edges 17 of the film 3.
