Definitions

  • the invention relates to flexible films used in the packaging of solid portions or semi-solid by folding.
  • packaged solid or semi-solid portions in flexible films mention may be made of food products such as broths KUB ®.
  • the film according to the invention has a much better resistance to the risk of punctures than the traditional film based on thin aluminum foil, and this both by the better mechanical resistance to punctures by the better resistance to corrosion.
  • the invention which has succeeded in combating the memory effect of the thermoplastic films during the folding phase, uses this same memory effect to facilitate the unfolding of said block by the end consumer.
  • the film according to the invention is significantly more economical than the films according to the prior art.
  • Figure 1 is a top view of the outer face of the film or portion of film (1) intended to form a package of a rigid or semi-rigid parallelepipedal block having a rectangular base of 32mm x 23mm, and 10 mm height.
  • the four marked areas (20) of cold sealing layer, hatched vertically, correspond to the formation, by folding, of the four side walls of the package to be formed.
  • Each of the four areas (20) comprises two parts (201, 202) which, after folding along the lines (203), are opposite and adhere to each other, thus fixing the side walls of the package to be formed .
  • the four marked areas (21) of cold sealing layer, hatched horizontally, correspond to the formation, by folding, of the upper wall of the package to be formed.
  • Each of the four areas (21) comprises two parts (211, 212) which after folding along the lines (213), are opposite and adhere to each other, thereby fixing the upper wall of the package to be formed.
  • On the film (1) is carried an arrow (6) indicating the direction of unwinding of the film on reel.
  • FIG. 2 is a bottom view of the interior face of the film or portion of film (1), having the same lateral positioning as in FIG. 1.
  • This inner face includes two lateral strips (3) non-stick, so that the marked areas (20,21) of the outer face do not adhere to the inner face and thus allow the unwinding of the film reel.
  • a marked area (4) of heat-applied varnish Between these two strips, and at one end of the portion (1) of film, is a marked area (4) of heat-applied varnish.
  • This area (4) is located a distance of 10 mm from the edge, so as to leave an opening zone (6) constituting for the consumer an easy grip of the film for the opening of the packaging formed.
  • the location of said cold sealing layer is chosen as a function of said folding, so that, during said folding, any identified area or portion of identified area is brought into contact, respectively, or from another marked area, or from another part of the same identified area, so that, after folding of said block, no free cold sealing layer remains.
  • cold sealing layer is meant a generic family of adhesive products, often known in themselves as “coldseals”, and which have the particularity of adhering cold to themselves.
  • cold active adhesives can be used which can adhere to said polyolefin-based film, but which do not adhere to this same film made non-stick.
  • said marked areas of cold sealing (20,21) are of half the surface area and are limited to one half (201, 211) of area (20,21).
  • said polyolefin-based film is preferably chosen from PP, OPP, metallized OPP, expanded PP with pearlescent appearance.
  • the inner face of said film must include a non-stick layer, possibly marked with respect to said marked areas.
  • a non-stick layer possibly marked with respect to said marked areas.
  • either the inner face of said PP-based film is made non-stick, or the inner face of said PP-based film is coated with a layer of non-stick varnish.
  • this layer of varnish (3) can be identified, as illustrated in FIG. 2.
  • said interior face can comprise said non-stick varnish in a marked layer, and a heat-sealing varnish in another layer marked, and offset with respect to said cold sealing layer, so that, in said film on reel, a layer of cold sealing of the external face of a turn, is not facing said layer of heat-sealing varnish from another turn.
  • This modality is intended to increase, when it is made necessary in particular by local climatic conditions, the tightness of the packaging formed, the sealing of beaches (20,21) only ensuring that the packaging formed is not likely to unfold.
  • Another object of the invention consists of the use of a film according to the invention for packaging food products in the form of rigid blocks or semi-rigid.
  • a film was made as shown in Figures 1 and 2.
  • a 32 ⁇ m thick OPP film was used with one side made non-stick.
  • a thickness of 4 ⁇ m of a commercial cold-sealing varnish (varnish based on acrylate) has been deposited, marked and along the ranges (20, 21) of FIG. 1 alkyl and natural latex).
  • a layer (4) of commercial fusible varnish (varnish based on alkyl acrylate) 4 ⁇ m thick was deposited.
