Definitions

  • the present description relates to a laminated material for containers, in particular for food use.
  • the present description also relates to a process for manufacturing this laminated material, as well as a sheet and a container obtained from this laminated material.
  • a known laminated material is provided with two layers of plastic material joined by a pressure adhesive also known as PSA (Pressure-Sensitive Adhesive), which adhesive allows the separation of a tongue obtained by incising one of the two layers.

  • the non-adhesive region is arranged outside the sheet obtained from this laminated material to form a container, in particular to close a tray.
  • the outer layer is not provided with incisions, so that the container is relatively difficult to manufacture and/or use.
  • WO 2011/032064 Al and US 2005/0276525 Al describe laminated materials provided with a non-adhesive region disposed in a limited area of the edge of the sheet which forms the container, close to an incision of the outer layer, so that also in this case the container is relatively difficult to manufacture and/or use.
  • the object of the present description is therefore to provide a laminated material free from these drawbacks. This object is performed with a laminated material, a manufacturing process, a sheet and a container, whose main characteristics are specified in the attached claims.
  • the laminated material according to the present description can be advantageously used for food containers which can be easily manufactured, as well as opened and closed, even several times, during use.
  • This advantage can be improved thanks to the particular shape and the particular arrangement of the incisions in the inner layer and in the outer layer.
  • the container comprising the laminated material does not require protuberances or labels for opening the container itself, thanks to the presence of the non adhesive region and to the arrangement of the first incision with respect to this region, so as to limit the overall dimensions and/or improve the appearance of the container.
  • the laminated material object of the present description allows a saving of adhesive material and allows to make the incisions of both layers through die-cutting, thus allowing to simplify the manufacturing process, especially if the laminated material is formed in a continuous strip from which a series of sheets suitable for closing food containers, for example bags or trays, can be obtained with an automated process and/or an automatic machine.
  • the laminated material can be advantageously used to close containers comprising two trays independently accessible one from the other.
  • figure 1 shows a top view of a first embodiment of the laminated material
  • figure 2 shows a bottom view of the laminated material of figure 1;

  • the width and/or the length of the first layer 1 are substantially equal respectively to the width and to the length of the second layer 2.
  • first layer 1 and/or the second layer 2 preferably comprise at least one film of plastic material, for example polypropylene, having a thickness of between 10 and 40 microns, while the adhesive is preferably a pressure-sensitive adhesive which allows both the separation of the first layer 1 from the second layer 2 by manual traction and their subsequent adhesion by pressing the first layer 1 on the second layer 2, and/or vice versa.
  • the first layer 1, the second layer 2 and the adhesive are substantially transparent, so that the resulting laminated material is substantially transparent.
  • the adhesive is arranged between the first layer 1 and the second layer 2 so as to leave at least one non-adhesive region 4, namely substantially free of adhesive or otherwise with a reduced adhesiveness, between the first layer 1 and the second layer 2, which is shown with dashed lines in figures 1 and 2 and is visible in figure 3.
  • the non adhesive region 4 can also be obtained by applying only within the perimeter of the same region a substance that completely or partially neutralizes a layer of adhesive uniformly applied between the layers 1 and 2. Therefore, the laminated material comprises at least one first adhesive region 5 and at least one second adhesive region 6, which regions are separated by the non-adhesive region 4 at least along most of their extension.
  • the non adhesive region 4 preferably forms a strip which is continuous and/or substantially parallel to a longitudinal axis L which can correspond to the direction of winding of the laminated material on a roller.
  • the first adhesive region 5 of the laminated material and the second adhesive region 6 of the laminated material have a substantially rectangular shape and are disposed respectively to the left and to the right of the non-adhesive region 4.
  • At least one first incision 7 is made in the first layer 1, so as to form in the first layer 1 a portion la which can be separated from the second layer 2 while keeping the remaining portion lb of the first layer 1 joined to the second layer 2.

In the present embodiment two first incisions 7 extend into the first layer 1 starting from the non-adhesive region 4 towards the first adhesive region 5 or the second adhesive region 6, respectively.
  • At least one second incision 8 in particular in the shape of a U or V, is made in the second layer 2, so as to form in the second layer 2 a tongue-shaped portion 2a which can be separated from the first layer 1 while keeping the remaining portion 2b of the second layer 2 joined to the first layer 1.
  • At least one end of the second incision 8 may be provided with a curl 9.
  • the second incision 8 can be at least partially surrounded by one or more first incisions 7.

  • the sub-portion lc of the portion la of the first layer 1 which is included between the first sections 7a of the two first incisions 7 forms a gripping tab which can be easily separated from the second layer 2, thanks to the non-adhesive region 4 arranged under the sub-portion lc, and grasped by a user to separate the portion la from the portion lb of the first layer 1.
  • the longitudinal axis L corresponds preferably to an axis of symmetry for the non adhesive region 4 and/or the incisions 7 and 8.
  • a portion of the laminated material can be cut and removed to be used as a sheet to close a container.
  • figure 2 shows with a dashed line the edge of the sheet 3 of the laminated material that can be cut and applied, for example by heat- sealing, on the edge (also shown with a dashed line) of a container 10, for example a food tray.
  • the second layer 2 can therefore be made of a heat-sealable material.
  • the non-adhesive region 4 connects to each other two opposite sides of the edge of the container 10, so that the adhesive regions 5, 6 are completely separated from each other by the non-adhesive region 4.
  • the sheet 3 can for example be used to make a food container 10 which can be easily opened and closed even several times during use.
  • the sheet 3 forms an opening 3a through which it is possible to access the inside of the container 10.
  • the tip of the tongue formed by the second incision 8 is preferably directed towards the sub-portion lc of the portion la of the first layer 1 arranged on the non-adhesive region 4.
  • the first incision 7 can have a substantially U-shaped shape further comprising a convex portion, in particular semicircular or lunette shaped, which defines a sub-portion lc of the portion la of the first layer 1 which is arranged at the non-adhesive region 4 and can act as a gripping tab for opening the container.
  • the second incision 8 can have a shape similar to that of the first incision 7 but smaller, so as to be at least partially surrounded, in particular completely, by the first incision 7.
  • the tip of the tongue formed by the second incision 8 faces the sub-portion lc of the first layer 1.
  • the first incision 7 can have a rectilinear shape and be placed at the non-adhesive region 4, in particular being substantially parallel to the latter, more in particular substantially parallel to the longitudinal axis L.
  • the second incision 8 may be semicircular or lunette-shaped so as to form a tongue with the tip facing the first incision 7.
  • the sub-portions lc of the portion la of the first layer 1 which are arranged on the non-adhesive region 4 near the edges of the sheet 3 act as a gripping tab to open the container.
  • the second layer 2 of the laminated material can be heat-welded on the edge (shown with dotted lines) of a container 10 comprising at least two adjacent trays lOa, lOb which can be placed side by side or joined together along two adjacent edges.

  • said adhesive layer is applied by two first auxiliary rollers continuously on the adhesive regions 5 and 6, while leaving between them a space which thus forms the non-adhesive region 4. Therefore, the non-adhesive region 4 preferably extends along the whole feed direction L of the laminated material.
  • the first layer 1 provided with the non-adhesive region 4 and the adhesive regions 5, 6 is then joined to the second layer 2 by second auxiliary rollers, so as to obtain a laminated material which can be wound on a third roller.

  • the first incision 7 and/or the second incision 8 can also be made before joining the first layer 1 to the second layer 2.
