Definitions

  • the present invention relates to a laminated packaging sheet of the type having a primary layer associated with a weldable layer between which is interposed, in at least one marked zone, a layer of a permanent adhesive, said sheet having in a marked area where the permanent adhesive is present, a heat-sealing region allowing the sealing by thermal welding of the packaging and allowing a reclosing packaging after an initial opening.
  • the polymer sheets simple or complex incoming in the composition of the package, undergo a treatment which makes it possible make them permeable to gases.
  • these treatments allow control of the atmosphere inside the packaging, particularly in regulating the permeation of the gases generated by the packaged product inverse gases from the outside atmosphere through the sheet thus treated.
  • the sheet then forms a permeable membrane.
  • Permeability conferred the leaf usually relates to oxygen, carbon dioxide and the water vapour.
  • these sheets can be perforated or micro-perforated.
  • the packaging made by heat sealing be it sachets or trays, can be closed to allow only a fraction of the packaged product in the package is consumed, the remaining fraction that can be stored for later consumption.
  • a shutter sheet with two layers of polymer between which is interposed a layer of a permanent adhesive.
  • the leaf is welded on a support according to one of the layers to ensure sealing of the packaging.
  • the welded layer is torn, thus revealing the permanent adhesive which allows a subsequent re-closing of the packaging.
  • DE-76 17 442 U discloses a sachet formed of a packaging sheet folded on itself.
  • the packing sheet has perforations only in its middle part and the opposite lateral margins of the sheet to be welded are devoid of perforations.
  • FR-A-2.741.605 discloses a laminated packaging sheet comprising a primary layer associated with a weldable layer between which is interposed a layer of a permanent adhesive.
  • This packing sheet which corresponds to the preamble of claim 1, is adapted to ensure the reclosing of a package after an initial opening.
  • the invention aims to provide a packaging sheet and packaging the package allowing both packages to be opened and closed several times and allowing the flow of gas between the interior and the outside of the package.
  • the subject of the invention is a packaging sheet, according to claim 1.
  • the invention further relates to a package according to claim 4.
  • the invention relates to a packaging bag according to claim 5.
  • the package 10 shown in FIGS. 1 and 2 is a bag intended to packaging fresh products such as vegetables or fruits.
  • the bag is formed of two rectangular main soft sheets 14, 16 disposed opposite and a bottom 18 consisting of a third flexible sheet.
  • the two main flexible sheets 14, 16 are connected to each other by thermo-welding along two longitudinal edges 20A and 20B.
  • the edge lower leaves 14, 16 is bonded by a weld to the edge of the sheet 18 forming background.
  • the two sheets 14, 16 are linked to each other.
  • the other an upper weld 22 arranged transversely of a longitudinal edge to the other.
  • This weld forms a means of opening and closing of the packaging. It is arranged at a distance from the upper edge sheets 14 and 16, thus forming, beyond the weld 22, two ranges free grip 14A, 16A.
  • the three sheets 14, 16, 18 define between them an enclosure 24 in which the packaged products are contained.
  • the leaves 14 and 16 constituting the main faces of the bag 10 have a laminated structure. These two leaves have for example the same structure.
  • Each has a primary layer 30 facing outward and a sealing layer 32 turned towards the inside of the bag. Between the layer 30 and the solder layer 32 is disposed a layer 34 of a permanent adhesive.
  • the longitudinal weld 22, made between the two faces opposite soldering layers 32, is a flesh-flesh type welding.
  • the two welding layers 32 are welded together by heat sealing.
  • each sheet 14, 16 presents, in a predetermined region 36 extending over most of its surface a treatment making the sheet permeable to gases.
  • This treated area 36 is represented by a grid of dots in the figures.
  • the upper boundary 37 of region 36 is separated from the weld 22 by a strip 38 left without treatment.
  • the weld 22 and the border 37 extend substantially in parallel to each other and are separated by a distance of between 4 mm and 2 cm and preferably greater than 7 mm.
  • the treated regions 36 extend over the entire width of the leaves 14 and 16 from one longitudinal edge 20A to the other 20B. They extend from the border 37 to the welding area with the bottom 18.
  • these regions are limited to windows located in the part of leaves 14 and 16. In this case, to carry out the treatment on the windows in question, it is necessary to print spots on the sheet for tracking.
  • the treatment rendering permeable to gases consists, for example, in the perforations distributed over the surface of the regions 36.
  • the perforations are made for example by means of an installation mechanical system comprising two cylinders rotating about parallel axes, these cylinders being in contact along a line of tangency.
  • One of the cylinders is equipped on its surface with a perforation matrix made in general made of metal.
  • the other cylinder forming a bearing surface is generally realized in a plastic material.
  • the matrix of perforations penetrates the surface the cylinder next to the line of tangency.
  • the film intended for forming the sheets 14 and 16 of the bags circulates between the two cylinders and thus found perforated with a set of holes by removal of material.
  • the level of gas permeability is adjusted by varying the density perforation organs, their size and applied pressure between the two cylinders.
  • the perforation matrix has a profile adapted and includes in particular beaches without perforating organs.
  • the beaches provided with perforating members form strips following the entire periphery of the cylinder carrying the matrix, or extend according to marked regions extending along generatrices of the cylinder.
  • the perforations are replaced by micro-perforations, formed without removal of material and forming incisions in the material of the sheets 14 and 16. These micro-perforations are obtained by passing each sheet between adjacent rolls, one of which has blades or micro-knives that may incise the next sheet all its thickness.
  • the gas permeability is obtained by performing micro-perforations using a discontinuous laser beam.
  • a laser beam modifies the structure locally of the material, thus creating micro-holes of defined diameter and in particular between 100 and 200 ⁇ m.
  • the level of permeability is adjusted by modifying the diameter of the micro-holes and their density.
  • a treatment rendering porous the sheet is applied, conferring on it a porosity.
  • This porosity is obtained thanks to two adjacent cylinders between which circulates the sheet, one of the cylinders being covered with a rough deposit, creating a weakening of the leaf.
  • the level of permeability can to be adjusted essentially by varying the pressure between the rolls of job.
  • the gas permeability is obtained by permeable treatment as described in European patents No. 351,115 B1 and No. 351,116B1.
  • the operator enters in each hand an extension of the leaves 14 and 16 constituting the gripping ranges 14A, 16A located beyond the weld 22. It then spreads the pieces opposite of the bag to cause the opening of the bag.
  • constraints are applied to the weld 22.
  • the welding layer 32 tears on both sides of the weld 22.
  • the two sheets 14, 16 of the bag are then separated, one still having on the inner side a welded strip 46 resulting from the welding layer 32 and the other sheet having a groove 48 corresponding to the imprint of the band 46.
  • the adhesive of the layer 34 remains attached to the layer 30 at the bottom of the bleed 48 and / or remains carried by the welded strip 46 to form thereon a tacky coating 50, as shown in FIG.
  • the opening region of the packaging formed by the welding 22, opens without risk of complete tearing of one of the sheets 14, 16, since the weld 22 is disposed away from the rendered region 36 permeable to gases.
  • the lack of treatment conferring gas permeability in the region of the weld 22 avoids creating tear primers leaves in this highly stressed area when opening, which spreads any risk of degradation of the leaves during the breaking of the welding layer 32.
  • the package 100 shown in FIG. 6, consists of a container circular 112 and a flexible cover 114 shutter a passage 116 access inside the tray.
  • the tray 112 consists of an outer support layer in suitable material, for example polyvinyl chloride, coated on its inner surface of a weldable layer, for example, polyethylene.
