Definitions

  • the invention relates to a laminated packaging sheet, of the type comprising a first film, a second film and an adhesive interposed between the two films, the sheet having an opening strip formed along its surface, which strip defines a priority propagation path for a break in the sheet, the opening strip comprising a mechanical weakening treatment.
  • an opening strip is formed on the surface of the sheet.
  • This strip defines a priority propagation path for the rupture of the sheet.
  • This opening strip comprises for example a mechanical treatment weakening formed over the width of the opening strip, this treatment weakening being carried out in a first film of the sheet.
  • Such an opening strip effectively facilitates tearing and propagation of the rupture along the course of the strip.
  • the tear may propagate outside the opening strip, away from the strip layout. Furthermore, if the traction exerted on the two parts of the sheet is not perfectly transverse to the band, the tear can spread outside of the opening strip.
  • the object of the invention is to propose a laminated packaging sheet. allowing a precise propagation of the rupture of the sheet during its opening, this propagation taking place along the route of an opening strip, even if this line is curved.
  • the subject of the invention is a laminated packaging sheet of the aforementioned type, characterized in that the opening strip is delimited laterally on both sides by a lateral border, each border separating an area outside the opening strip where the two films are held glued to each other at least along the lateral border and a lateral area of the opening band bordering the lateral border and free of adhesive between the two films, and in that the mechanical treatment is exactly confined between the two borders outside the areas outside the strip where the two films are bonded.
  • the invention further relates to a packaging comprising at least a sheet as defined above.
  • the bag 10 shown in Figure 1 is intended, for example, to the packaging of a chocolate bar. It has a sheet 12 folded over itself whose two opposite longitudinal edges are linked to each other by a longitudinal weld 14. At each end, the sheet folded over itself and forming a tube is closed by transverse welds 16.
  • the sheet 12 has an opening strip 18 extending transversely across the width of the sheet.
  • the opening strip 18 extends parallel to an end weld 16.
  • the opening strip has a width between 5 mm and 3 cm.
  • This opening strip formed on the surface of the sheet, defines a priority propagation plot for leaf rupture after initiation a tear.
  • the strip opening 18 defines a straight line.
  • the opening band extends mainly outside the regions welded from the packaging, except for the longitudinal weld 14 which it crosses.
  • the laminated packaging sheet according to the invention comprises, as illustrated in FIGS. 2 and 3, an exterior film 20 and an interior film 22.
  • the outer film 20 is for example a bi-oriented plastic film such than polyethylene terephthalate, bi-oriented polypropylene, polyamide bi-oriented, polyvinyl chloride or cellulosic film.
  • the inner film 22 has a thickness greater than the outer film 20. It preferably constitutes a welding film allowing the sheet to be welded packaging by heat sealing on itself or on a tray.
  • the inner film 22 is for example a bi-oriented film of polyamide type bi-oriented or polyester, a non-oriented film of polyethylene type or cast polypropylene, a layer of varnished aluminum or a layer of paper covered with a sealable coating.
  • the two films 20 and 22 are laminated to each other by a layer discontinuous adhesive 24.
  • the two films 20 and 22 are glued to each other by the adhesive 24 at least along the lateral borders 25 delimiting the opening strip 18.
  • films 22 and 24 are glued over their entire surface, outside the opening strip 18.
  • the opening strip 18 has on either side a lateral area 26 bordering each lateral border 25, these lateral areas being free of adhesive between the two films.
  • the opening strip 18 includes a treatment mechanical weakening 27, this mechanical treatment being confined exactly between the two borders 25 outside the areas outside the opening strip 18 where the films are glued.
  • the two ranges side 26 of the tape free of adhesive connect to each other to form a single line free of glue extending from one border 25 to the other.
  • the mechanical treatment weakening 27 consists of a set of perforations 28 passing through right through the outer film 20.
  • the mechanical weakening treatment is carried out away from the borders 25 thus leaving untreated margins on both sides of the treated region 29.
  • FIGS. 1 to 3 With a packaging as illustrated in FIGS. 1 to 3, it can be seen that, during the initiation of a rupture of the packaging in the opening strip 18, the rupture of the sheet spreads along the path of the opening strip 18, even if the traction exerted on the two parts of the packaging is not strictly transverse to the opening strip.
  • the mechanical weakening treatment 27 is produced not by a set of through perforations 28 but by non-emerging surface irregularities formed on the surface of the outer film 20.
  • the irregularities of non-emerging surface denoted 32 are provided on the surface exterior of the exterior film 20.
  • the surface irregularities noted 34 are formed on the surface interior of exterior film 20.
  • the mechanical treatment weakening extends away from the borders 25.
  • the processing mechanical attenuation 27 extends over the entire strip surface opening 18, that is to say over the entire line free of glue.
  • the treatment does not, however, extend over the bonded regions outside the strip Opening 18.
  • the opening strip 18 comprises transversely, along its entire length, a central area 35 in which adhesive 24 is disposed at least locally between the two films. On either side of the central area 35, the opening strip 18 has two lines 36 free of adhesive laterally bordering the surface central 35.
  • the two lines 36 free of adhesive have a width of between 0.5 mm and 3 mm.
  • the mechanical weakening treatment 27 formed in the opening strip is formed, at least in the central area 35. This mechanical weakening treatment is carried out in the outer film 20.
  • This mechanical weakening treatment consists, for example, a set of perforations 28, as illustrated in FIG. 8, or else by irregularities 32 formed on the outer surface of the outer film 20, as illustrated in FIG. 9, or by irregularities 34 formed on its inner surface, as illustrated in figure 10.
  • the mechanical treatment attenuation extends exactly over the entire surface of the beach central 35, the adhesive extending itself over the entire surface of this area Central.
  • the processing mechanical weakening extends on both sides beyond the central beach 35 and partially extends in the region of the lines 36 free of adhesive.
  • mechanical weakening treatment extends away from the borders 25 laterally delimiting the opening strip.
  • margins 29 devoid of processing are formed along borders 35.
  • the mechanical treatment weakening extends to the borders 25 bordering the opening strip. However, mechanical weakening treatment is maintained in the opening strip between the two borders, without overflowing beyond borders on the bonded regions outside the opening strip.
  • the mechanical treatment weakening 27 extends only in the middle region of the range central 35, away from the lateral stripes 36 free of adhesive. Margins 37 without mechanical weakening treatment are thus defined in the central area 35, along the lines free of adhesive 36.
  • the central area 35 has, along the lines 36 free of adhesive, two parallel lines of adhesive 38 separated by a region 40 without adhesive.
  • This region 40 constitutes the middle region of the central area 35.
  • a mechanical weakening treatment 27 is provided on the film outside 20 only and exactly on the surface of region 40 without adhesive.
  • the expression “exactly” means over the entire surface of the region considered, however taking into account manufacturing tolerances which are of the order of 0.2 mm.
  • the mechanical weakening treatment 27 consists of in a set of surface irregularities 42 not emerging on the outer surface of the outer film 20.
  • the irregularities surface area not marked 44 are provided on the surface interior of exterior film 20.
  • uneven surface irregularities are replaced by a set of through perforations.
  • the sheets illustrated in Figures 15 and 16 are variants of production, respectively, of the sheets of FIGS. 13 and 14.
  • an intermediate film 50 is interposed between the adhesive 24 applied discontinuously and the inner film 22.
  • the intermediate film 50 is for example a bi-oriented film such as polyethylene terephthalate, bi-oriented polypropylene, bi-oriented polyamide, polychloride vinyl or cellulosic film.
  • This layer 52 extends along the entire surface of the intermediate film 50.
  • Such an intermediate film can be used between the inner film and the adhesive in all the embodiments described in the previous figures and following.
  • the sheet illustrated in FIG. 17 includes, as before, an outer film 20, an inner film 22, between which an adhesive is interposed 24.
  • the central area 35 is bordered by two lines 36 free of adhesive.
  • the central area 35 comprises, transversely along its entire length, an alternation of lines 56 comprising of adhesive and lines 58 free of adhesive, the lines extending parallel to each other along the entire length of the strip opening.
  • Lines 56 with adhesive extend along the glue-free lines 36.
  • n lines 56 there are (n-1) lines 58.
  • Lines 56 and 58 each have a width of between 0.5 mm and 2 mm and preferably substantially equal to 1 mm.
  • lines 56 and 58 have variable widths depending on the width of the central area.
  • the lines placed in the middle region are narrower than the lines placed on the edges.
  • the outer film also has a mechanical weakening treatment 27 made up of non-emerging surface irregularities on its outer surface.
  • the treatment is spared on its internal surface.
  • the irregularities of non-opening surface can be replaced by perforations therethrough.
  • Figure 19 is illustrated a bag substantially similar to that of Figure 1 showing two opening strips 118 and 218.
  • the opening strip 118 is straight and extends from a longitudinal edge from the packaging to its end seal 16. This strip 118 allows you to remove a corner of the packaging to cause opening.
  • the opening strip 218 also connects a longitudinal edge of the packaging at its transverse weld 16. However, the strip layout opening 218 is curved, thus defining, after removal of the defined corner through the opening strip, a profile opening spout suitable for dispensing items contained in the bag.
