Definitions

  • This additional pull tab can be made of a line or a thin strip made either of synthetic or natural resin or of metal; it can be applied in many ways inside or outside the package.
  • the pull tab is applied in the product packaging step, and it is a "complication" of the process; in fact, additional material and suitable equipment to apply it to the package film are necessary. Furthermore, in order to avoid the breaking of the pull tab when opening the package, it must have a higher maximum tensile strength than the package film's.
  • the present invention aims at giving the package the easy-opening property without applying an additional pull tab.
  • a further aim of the invention is realizing a package where the pull tab is obtained directly in the mono or multi-layer film, which the package consists of when manufactured.
  • Another aim of the invention is the possibility to apply it to the opening of packages which present an area with low opening resistance of sealing; such a low resistance area is obtained realizing, in the tear starting area and in the surrounding space, a layer of film on which a heat-seal lacquer is applied at register.
  • the invention is then applicable either to package where the characteristic of perfect airtight sealing is not required (type A), or to perfectly airtight package, where it is possible to create an "area with low opening resistance of sealing" (type B), thanks to the presence of a heat-seal lacquer, in the sealing area surrounding the tear area.
  • type A packaging is the frozen food flexible mono or multi layer package: in this case the perfect airtight sealing is not indispensable, as frozen food is solid, in blocks, and it is packaged, stored, transported and sold in such a condition that contamination of external agents is impossible.
  • type A is the overwrap package of single packages, that is a (secondary) package containing two or more packages (primary package).
  • a reserve in the area of transversal sealing is realized(or can be realized), which creates a "breathe channel", to let excess air out of the package, to reduce the size during storage, transport and sale.
  • FFS Form-Fill-Seal
  • Such lacquer applied at register on the film in the sealing area, allows the airtight sealing of the package and, at the same time, reduces the pull strength as the tear of the pull tab takes place inside the lacquered area. Such a reduction takes place stimulating the adhesion lacquer-lacquer lacquer-film.
  • the opening resistance of sealing in this area must be high enough, to ensure the airtight sealing of packaging in the time, yet lower than the mechanic resistance of the pull tab, to avoid its breaking at opening.
  • Tab. 1/8 in fig. 1 shows a package with an integrated easy- opening system.
  • Tab. 2/8 in fig. 2 shows an example of the scribed section of a package, following the patent guidelines, where the scribing affects a part of the thickness of the outer film.
  • Fig. 3 hypothesize a scribing which affects the whole thickness of the outer film.
  • Tab. 3/8 in fig. 4 refers to a scribing which partially affects the inner film.
  • Fig. 5 shows a section with two different scribing depths.
  • Tab. 4/8 in fig. 6 is an example of a package where the tear starting area and the related pull tab are highlighted.
  • Tab. 5/8 in fig. 7 hypothesize a phase of partial pull of the tab.
  • Tab. 6/8 in fig. 8 shows a package where an area with low opening resistance of sealing has been realized through heat-sealing lacquer.
  • Fig. 9 shows the view from the top of the area affected by heat-sealing lacquer.
  • Tab. 7/8 in fig. 10 and 11 shows the situations of fig. 2 and 3 , designed with the application of the heat-sealing lacquer in the area with low opening resistance of sealing.
  • Tab. 8/8 in fig. 12 and 13 shows the situation of fig. 4 and 5 , designed with the application of the heat-sealing lacquer in the area with low opening resistance of sealing.
  • the outcome of a easy-opening system is obtained partially scribing, along two parallel segments (1) and (2), the mono or multi-layer film (3) which the package is made of.
  • the pull tab (4) consists of the strip of package material delimited by the perimeter of the package and by the two parallel segments (1) and (2).
  • Such segments of partial scribing are positioned so as to result, after the package manufacturing of the wrapper machine, perpendicular to the sealing (5), at a distance of about cm 1 ⁇ 3 between them, and inside the unsealed area or in the area with low opening resistance of sealing(6).
  • the final user pulls (removing it) the pull tab in the direction parallel to the scribing.
  • the removal has been made possible as the film scribing reduces the mechanic resistance and triggers a preferential direction for the cut propagation.
  • the scribing along the segments (1) and (2) can be as such to have a different depth (H 1 > H 2 , with H 1 equal to the thickness Sp of the film) compared to the thickness of the mono or multi-layer film along its length. This allows to realize a strip of film partially detached from the whole package, which represents a area of "invitation to opening"(7).
  • Manufacturing of the package object of this invention is based upon the newest printing, lamination and cutting technologies for mono and multi-layer flexible package.
  • the realization of the integrated easy-opening system that is the scribing of two segments (1) of the integrated pull tab, can be realized during the step of reel slitting, through the scribing ⁇ cutting systems, which can be both mechanical and based upon the technology of the so called laser scribing.
  • Both scribing ⁇ cutting systems allow partial and "at register” scribing of the mono and multi-layer film both at constant scribing depth and at "variable" depth.
