Definitions

  • the object of the present invention is a novel continuous band which has windows that are closed by fragments of plastic material, these fragments have a plurality of holes evenly distributed on their surface.
  • the continuous bands for the manufacture of bags are well known, by means of the union of their longitudinal edges, to configure a continuous fragmentary tube in a plurality of sectors corresponding to respective bags.
  • the bags When the product containing the bags are fruit and vegetable products and similar the bags have to provide adequate aeration of the same, which is achieved in very different ways, among which it can be mentioned that the material of the bag is reticular or that the band has Closed windows usually through network fragments, these solutions also allow consumers to see the packaged product.
  • the present invention advocates a continuous band which, to close the windows, incorporates fragments of plastic material that have a plurality of holes uniformly distributed throughout its surface, which solves the above drawbacks allowing printing in areas without windows and visual inspection of the product.
  • the weight of a plastic material fragment with its corresponding holes that offers the same mechanical resistance as a network fragment of equal dimensions is around 40% lower, so that there is a saving in the materials used which entails a monetary saving and Lower expense of products that are difficult to dispose of when they become waste.
  • the lightened continuous band for the manufacture of bags for fruit and vegetable products and the like which is the object of the present invention, consists of a continuous plastic sheet of width equal to the width of said band, said band disposes in each of the mentioned sectors of one or more windows of the same or different size; at least one of the windows is closed by a fragment of formal and thi-dimensionally suitable plastic material to said at least one window and fixed by its edges to the periphery thereof by heat welding or similar procedure, the said fragment of plastic material has a plurality of punched holes of equal size that are evenly distributed over the surface of said fragment.
  • a solution at first sight similar, could be that the continuous sheet lacked windows and stamped on its entire surface or in previously chosen areas a plurality of holes, but this would imply, that to obtain a bag with the same mechanical resistance as that obtained from the present invention, that the thickness of the continuous plastic sheet be greater; so that the savings in material and costs would disappear in addition to increasing the environmental problems generated by discarding the bags,
  • Figure 1 shows a perspective view of a continuous band sector.
  • Figure 2 shows a perspective view of a sector of the continuous band
  • Figure 3 shows a perspective view of the fragment of plastic material.
  • Preferred embodiments Figures 1 to 3 show a preferred embodiment of the lightened continuous band for the manufacture of bags for horticultural products and the like, which is the object of the present invention and incorporating a handle (4).
  • the continuous band (1) is configured by a continuous sheet (2) of plastic of width equal to the width of said band, said band has in each of said sectors sectors of one or more windows (5) of the same or different size; at least one of the windows is closed by means of a fragment (3) of plastic material, formal and dimensionally suitable for said at least one window, and fixed by its edges to the periphery thereof by thermosoity or similar procedure, the said fragment of plastic material has a plurality of holes (6) punched out of equal size that are evenly distributed over the surface of said fragment. Said holes may have a square shape with their rounded vertices and be arranged to the triplet to give a net appearance.
  • the band can have a plurality of perforations of the same or different size to favor the aeration of the product packaged in its bag manufactured with it.
  • These windows can be centered in each of the sectors or arranged symmetrically with respect to the longitudinal axis of the band, in these two cases the fragment of plastic material can be a strip of smaller width than that of the continuous band.
  • reinforcements of plastic material are provided in the areas provided for the handles , the fermosoldaduras and in the edges of the windows, these reinforcements are united to the face of the continuous sheet of matter! plastic intended to be the inner face of the bags by thermosoity or similar procedure.
