Definitions

  • the qualification of longitudinal and transverse is made with reference at the winding of the film which provides the films for forming the sachet, the longitudinal direction being this direction of the winding and the direction of film running through its manufacturing and printing machine and that of the film running through the packaging station.
  • the various embodiments may include security means allowing the consumer to check whether the sachet has already opened before use or before purchase.
  • FIG. 1A shows a rectangular film 10 cut from a film unwound from a roll and which runs in the longitudinal direction represented by the arrow MD (machine direction) through the machine packaging.
  • the film 10 has two parts 12, 14 of height A symmetrical about a fold line 16, the upper part being extended by a tongue 18 of height B.
  • Parts 12 and 14 have, along their edge, two transverse bands 20 and 22 cold sealing plaster and two longitudinal strips 24, 26 of plaster cold sealing that extend between the cross strips for form a symmetrical rectangular frame around the fold line 16. If the transverse bands 20, 22 extend along the edges, the longitudinal strips 24, 26 can be slightly set back, up to 1 cm.
  • a typical example of a usable cold sealing coating is product IP 7905 or IP 7936 from Sun Chemical Swale.
  • the substrate of the film can be a Vifan OPP-CY metallized bioriented copolymer.
  • the bag thus formed is hermetically sealed on the four sides which allows a good conservation of the packaged product. Furthermore, the tongue which is free over the entire height B provides a excellent possibility for the user to take the sachet for separation adhesive strips, in particular longitudinal strips 24 and 26. It note that the thickness of these has been exaggerated in Figure 1C for the needs of illustration.
  • FIG. 2A shows a film 30 similar to film 10 of the Figure 1A for the production of a bag as shown in the figures 2B and 2C.
  • the one of Figure 2A has on the tongue 18, near the rear face 12, an additional longitudinal strip 32 of sealing plaster cold which is arranged so that when the tongue 18 is folded down on the front face 14 in order to close the bag, the line of folding of the tongue 18 is located substantially in the middle zone longitudinal of this strip of sealing plaster 32.
  • This strip 32 ensures, therefore, by adhesion on itself a good maintenance of the tongue in its closed position of the bag according to Figures 2B and 2C.
  • Example of making a 40 or 50 film Example of making a 40 or 50 film.
  • a double layer structure is produced, the outer layer of which comprises a transparent printed film of oriented polypropylene copolymer with a thickness of 25 microns.
  • a lacquer or "primer” (type 10-612 205 MX 41 from Siegwerk) can be applied.
  • Printing can be carried out by various techniques well known in the field in question, such as gravure printing, flexography, offset or others.
  • a lacquer having non-stick properties with regard to cold sealing coatings is applied to the entire outer surface of the film.
  • Such a non-stick lacquer generally consists of a polyamide resin mixed with polyethylene resins (type 10-609 345 -3P from Siegwerk) at a rate of 1.5 g / m 2 .
  • Another possibility is to provide under the inner edge of the tongue an adhesive strip which, until the first use, is neutralized by a silicone band. When the consumer wishes close the bag it will only have to remove this silicone band to make adhere the adhesive strip to the front of the bag.
  • This band adhesive could of course also be provided on the front from the bag, below the tab.
