Definitions

  • the present invention relates to packaging and in particular to easy opening flow-pack wrapper intended to be used in a horizontal or vertical form, fill and seal process for rigid or semi-rigid products.
  • a fin seal is a seal where the packing wrapper is sealed face to face in machine direction (or longitudinal way). This seal is an "inside-inside” seal, in opposition to an overlap seal, which is an "inside-outside” seal.
  • the sealing wheels sealing the fin seal are responsible for the transport through the machine together with some guiding wheels.
  • the packed products moves over a horizontal conveyer belt and runs via the folding box into the formed tube.
  • the cross-seals are formed through the cross-sealing jaws.
  • the end seal of a pack is formed together with the beginning seal of the following pack.
  • the film is cut to split the adjacent pack and the cutting knife is generally built into the sealing jaws.
  • a normal flow-pack is opened by tearing, starting at the profiled cross-seal. This tear is generally not guided, which means that the opening is unpredictable and has as a consequence the impossibility of a correct reclosability. Furthermore, all pre-cuts of the prior art wrappers, do not cross-over the longitudinal fin seal of the wrapper and the tearing is generally stopped by this longitudinal fin seal and from that point makes it unpredictable. If the tear power is increased, a piece of the pack brakes off, or the tear continues in a random way.
  • a tear strip in the packaging. This tear strip is sealed at the inside of the pack and allows to guide the tear. If a tear tape is fixed to the wrapper in the cross-direction, the tear also stops at the longitudinal fin seal, while tearing the pack beginning from the tear tape tear initiation. Most of the tear tapes in the market are not heat-sealable but cold-sealable with a pressure sensitive glue already on the tape, taking care of the seal. The disadvantages of this method are the high costs and negative effects on the packing speed. Besides that, a tear tape has a negative influence on machine speed if it is put on the wrapper on cross direction. In machine direction however, in most cases the speed can be maintained.
  • Document DE 10026551 A1 presents a pre-cut in the longitudinal fin seal of a flow-pack wrapper used as a multi-pack wrapper for tablets.
  • the pre-cut does not cross-cut the longitudinal fin seal to preserve the air tightness of the pack.
  • the present invention aims to provide an easy opening flow-pack wrapper with predictable opening, intended to be used in a horizontal or vertical form fill and seal process not entailing reduction of packing speed on a usual packing equipment.
  • Another aim of the present invention is to present an easy opening flow-pack wrapper which is reclosable via a cold-seal area exhibiting a particular pattern design.
  • the present invention discloses an easy opening flow-pack wrapper for rigid or semi-rigid products comprising a longitudinal fin seal, a closing cold-seal area and an opening initiation characterised in that said longitudinal fin seal is situated on the longitudinal edge of the product, and in that said opening initiation is situated in said closing cold-seal area, and cross-cuts said longitudinal fin seal.
  • said package further comprises at least one reclosable cold-seal area and at least one tear guide cold-seal free area, said tear guide area being situated in between said closing cold-seal area and the adjacent reclosable cold-seal area in the prolongation of the opening initiation.
  • said reclosable cold-seal area has a lower seal strength than said closing cold-seal area .
  • said reclosable cold-seal area has a specific pattern design allowing a progressive opening and a "push-through" of the semi-rigid or rigid product.
  • An additional feature of the present invention is that the specific pattern design of said reclosable cold-seal is a banana, a triangle, a multi-triangle or a dot pattern.
  • said opening initiation is a mechanical weakening such as pre-cut and/or a perforation and/or an embossing.
  • the present invention discloses an easy opening flow-pack wrapper intended to be used in a horizontal and/or a vertical form, fill and seal process.
  • Fig. 1 shows a mask of the closing cold-seal area on the unfolded wrapper (first embodiment)
  • Fig. 2 shows a mask of the closing cold-seal area and the reclosable cold seal area on the unfolded wrapper (second embodiment)
  • Fig. 3 shows the cold-seal area on the unfolded wrapper with an embossed mechanical weakening as opening initiation.
  • Fig. 4 shows the pattern of the closing cold-seal area and the reclosable cold seal area on the unfolded wrapper with a perfored mechanical weakening as opening initiation.
  • Fig. 5 shows the profile of a folded flow-pack wrapper with longitudinal fin seal situated on the longitudinal edge of the product.
  • Fig. 6 shows the profile of a folded longitudinal fin seal on the folded flow-pack wrapper.
  • Fig. 7 represents a perspective ceremonies of a packed product showing the pre-cut crossing the longitudinal fin seal.
  • Fig. 8 represents a mask of the opening possibility at two sides of the pack with closing cold seal areas and reclosable cold seal areas.
  • the present invention is based on the technology of a flow-pack used in a horizontal or vertical form fill and seal process.
  • This flow-pack wrapper is easy to open (first embodiment) and preferably, but not necessarily, reclosable (second embodiment).
  • the modifications on the wrapper of the present invention do not entail a significant reduction of the packaging speed and can be achieved on standard packing machinery without significant extra costs.
  • cold seal refers to an area of the flexible packaging film covered by a sealing coating able to seal to itself without melting of the polymer film and essentially by the application of pressure. This concept is well known by those skilled in the art.
  • opening initiation refers to all kind of mechanical weakening intended to initiate the tear of the package independently of the generation process of this mechanical weakening.(perforations, full pre-cuts, notches, embossing...etc). As far as it would be endless to describe all the existing mechanical weaknesses, they should be understood in a wide range, independently of their pattern.
  • a pre-cut can for instance start inside a cold-seal area instead of starting at the edge of the pack.
  • cross seal or "transverse seal” should be understood as the sealing in a transverse direction to the flow direction of the wrapper during the pack process.
  • the cross seal is perpendicular to the longitudinal fin seal, said longitudinal fin seal being parallel to the longest edge of the packed product.
  • wrapper should be understood in a large sense as a mono or multilayer packaging film which is optionally printed and generally coiled, and cutted into strips to be used in form, fill and seal processes. After the production process of such coils, well known by those skilled in the art, the semi-finish wrapper is used to wrap a multitude of products, transforming them into wrapped products using the wrapper of the present invention.
  • the longitudinal fin seal 9 is situated on the longitudinal edge of the product and cross-cut by the opening initiation. This allows the continuation of a predictable tear.
  • the longitudinal fin seal 9 is also situated on the longitudinal edge of the product and cross-cut by the opening initiation, but additionally, a reclosable cold seal area 6 adjacent to the closing cold seal area 2 in the cross direction is added to the packaging.
  • a cold seal free area 5 subsist in between said closing cold seal area 2 and said adjacent reclosable cold seal area 6 which guides the tear automatically in between both zones.
  • the reason for this guidance is that the tear chooses the way of the lowest resistance.
  • the non adhesived multilayer film/film is less tear resistant than the multilayer complex film/cold seal/cold seal/film. The adhesion of the cold seal layer to itself increasing even this tear resistance.
  • the converting process is based on the production of a normal cold-seal wrapper, preferably, but not necessarily, with a special cold seal pattern design.
  • the closing cold-seal area 2 contains a cold-sealing coating in a quantity of about 3 to 5 grams per square meter.
  • the reclosable cold-seal area 6 has a lower seal strength than the closing cold seal area. This lower seal strength can be reached by different means. No limitative examples of such means are, a lower quantity of cold-sealing coating (only 2 to 3 grams per square meter), the use of a very dry cold-seal and/or the use of specific pattern design.
  • substrates used in the standard flow-wrap technology can be used in the present invention.
  • No limitative examples are mono and/or multilayer polymer films in general, and in particular aluminum coated and bioriented polypropylene mono and/or multilayer films.
  • the packing of the product is performed on a standard horizontal or vertical form, fill and seal machine with slightly adapted sealing jaws.
  • the knife in the sealing jaws should preferably be straight.
  • the sealing jaw area at one side has a specific design adapted to the desired pattern.
  • a cutting knife in the sealing jaw to make a pre-cut in the cross-seal. This pre-cut has to be made in the closing cold-seal area 2 to guarantee hermetic or semi-hermetic packs.
  • opening initiations such as perforations, tear initiations by mechanical or laser weakening or embossing are also possible and should also be situated in the closing cold-seal area 2 to ensure said hermetic or semi-hermetic packaging.
  • the easy opening of the wrapper of the present invention is possible by the fact that there are no profiled ends to have a "fool-prove" packaging. If the consumer cannot tear from the end, he is obliged to use the "side possibility”.
  • the easy opening is possible through opening initiation in the closing cold seal area 2 in the prolongation of the tear guide cold-seal free area 5.
  • the tear is guided through the cold-seal free area 5 to the other end of the wrap and the consumer takes away the major part of the closing cold-seal 2 and the remaining reclosable cold-seal 6 can be "pushed through” by the packed product.
  • This particular reclosable cold-seal area 6 with lower seal strength can be improved in terms of easy opening by the use of particular banana-shaped cold-seal patterns, triangle or dots, so that the product only touches this particular reclosable sealing area at one point and makes the "push-through” easier (see Fig 3).
  • the reclosability is possible by pushing the reclosable cold seal area 6 at the open end of the flow-wrap against each other. Due to pressure and human temperature, this is easily resealed.
  • the present invention can be used in different configurations. No limitative examples are easy openings on each side of the pack such as represented in figure 8. Multi-packs (not represented) are also part of the present invention. Such multi-packs can be separated by a closing cold seal area 2 and equipped with opening initiations according to the present invention on each side top and/or bottom.
  • a heat seal coating of 3 to 5 grams per square meter can be used according to the same concept.
  • the opening initiation is again placed within the sealed area and cross-cuts the longitudinal fin seal placed on the longitudinal edge of the packed product.
  • Typical heat seal coatings for this application are:
  • the problem in the present invention to be solved was to create the possibility of a reclosable package by a cold seal.
  • To develop such a seal it was first necessary to develop a flow wrapper with a predictable tear, to make it correctly reclosable.
  • the predictable tear has been obtained by placing the longitudinal fin seal 9 on the longitudinal edge of the packed product (see Fig.5 and 6) making it possible to place a cross-cutting opening initiation over said longitudinal fin seal 9.
  • the discovering of this possibility by the inventors not only improves the opening of non-reclosable packs (first embodiment) but also offers the possibility of the use of a reclosability concept by the presence of a reclosable cold seal 6 (second embodiment).
