Definitions

  • the present invention relates to the packaging of compressible insulating products, in particular with a view to their transport or their storage. More specifically, the invention relates to a package comprising compressible insulating products which are provided in the unitary state in the form of rolls or of substantially parallelepipedal batches of panels. The invention also relates to a method of manufacturing such a package, and to a palletized assembly comprising such packages.
  • Fibrous insulation products such as glass wool or other mineral wool felts, are low density products that occupy a large volume. In order to facilitate their transport and storage, it is desirable to limit the size of these products and to produce palletizable loads.
  • the insulating products in the unit state are conventionally packaged in a compressed state, being coated with a protective envelope generally made of kraft paper or plastic, the insulating products then being assembled in the form of rows and then positioned on pallets.
  • a constraint for packaging is that the deformations generated during compression of the insulating product must not degrade its capacity to recover thickness on deconditioning, the insulating qualities of the product being dependent on this recovery in thickness.
  • Another constraint is the need to protect the insulating product from the external environment, in particular when it comprises a binder sensitive to the effects of humidity.
  • the protective envelope making it possible to maintain the product in the roll state, or to bring together a series of panels in a batch, does not generally cover the entire external surface of the product and is therefore not sufficient to ensure complete protection against humidity.
  • EP0220980A1 describes a package in which a module is formed by juxtaposing several insulating products in a row, and wrapping the row using a film sealed on itself. Several modules are then superimposed on a pallet and the whole is assembled by wrapping.
  • One disadvantage of this type of packaging is that, even if the rolls or the batches of panels are protected by the wrapping film, they are however no longer protected, in particular at their ends, once the palletized assembly has been opened or damaged. There is then a risk of water infiltration into the insulating product, which can lead to a degradation of its insulating properties.
  • Other packaging is known by WO2004103821 and US2013067861 .
  • the invention more particularly intends to remedy by proposing a packet of compressible insulating products making it possible to preserve the quality of the insulating products, in particular in terms of thickness recovery.
  • each module of a package according to the invention comprises a single row of insulating products arranged one beside the other, successively in the first direction perpendicular to the longitudinal axes of the insulating products, the insulating products of the single row having their longitudinal axes parallel to each other.
  • the second film then envelops the single row of insulation products, covering part of the peripheral surface of the insulation products in the row.
  • cover when it is used alone should by default be understood as designating a cover which envelops a stack of modules.
  • cover when reference is made to a cover of a palletized assembly, which is distinct from a cover which surrounds a stack of modules, it is systematically specified that this is an “external cover”.
  • the insulating products can be rolls.
  • the insulating products can be batches of several panels assembled beforehand, for example by means of a heat-shrinkable film, these batches having a substantially parallelepipedal shape and having a footprint similar to that of the rollers.
  • the stack of modules which corresponds to a stage of modules in a palletized assembly, is completely covered by the combination of the second film and the cover.
  • packets of insulating products are obtained, intended to form all or part of a stage in a palletized assembly, which are watertight.
  • the stack of modules is enclosed within a package, formed by the combination of the second film and the cover, which covers all of the faces of the stack of modules.
  • the invention makes it possible to produce very simply palletized assemblies of rolls or panels, by superimposing several packages in accordance with the invention each corresponding to a stage of the palletized load, while ensuring that the insulating products in each package are protected from moisture or other external contaminants even when opened or damage to the external protection of the palletized assembly, which may be a wrapping film or a stretch or shrink cover.
  • the insulating products comprise a binder which is sensitive to humidity, such as a bio-sourced binder, in particular based on saccharides, sugars and / or sugar alcohols.
  • Such palletized assemblies can be stored outside, without further precaution, without risk of deterioration of the quality of the insulating products and in particular without problem of thickness recovery.
  • the second film forms, around the row of insulating products, a sleeve with an axis parallel to the longitudinal axes of the insulating products. More precisely, the row of insulating products has two main faces and two transverse faces perpendicular to the ends of the insulating products, and the second film envelops the row of insulating products, extending over the main faces and the transverse faces of the row.
  • the second film envelops the row of insulating products in a compressed state of the insulating products against each other in the first direction.
  • This compression in the first direction which comes in addition to the compression of each insulating product provided by the first film, helps to limit the size of the packages of insulating products in accordance with the invention.
  • the first film and the second film are plastic films having relatively low extension properties.
  • each of the first film and the second film preferably exhibits a stress at 10% elongation greater than 15 MPa, preferably greater than 17 MPa or 20 MPa, in the direction of extrusion and in the direction transverse to the direction of extrusion.
  • the stress can be measured according to the ISO 527/3 standard, on standard film samples. According to this standard, the elongation of the film is measured for an increasing tensile force applied to the film (measured in MPa) and a standardized speed.
  • the compression of each insulating product and the compression of each row of insulating products can thus be obtained and maintained, respectively, by a first single film and by a second single film.

  • the cover has an opening at the level of a main face of the stack perpendicular to the second direction.
  • the edge of the cover and the second film present on this main face of the stack are not linked together, which makes the method of manufacturing the package in accordance with the invention particularly simple. , fast and economical, while having a high protection in particular against the infiltration of water inside the package thanks to the continuous overlap of the cover and the second film.
  • the edge of the cover and the second film present on this main face of the stack can be linked together, for example by gluing or by welding.
  • the opening of the cover may be located at a transverse face of the stack perpendicular to the first direction.
  • the cover necessarily covers the two end faces of the stack.
  • This arrangement is less advantageous than the previous one, because the edge of the cover delimiting the opening is then located on the periphery of a face of the stack which is formed by curved peripheral sides of the various modules of the stack, which are covered by several separate second films, which does not guarantee a continuous overlap between the cover and the second films. It is then more difficult to seal the package.
  • the cover has no opening and covers all six sides of the stack.
  • the cover can be placed on the stack of modules in a hooding device allowing, after the cover has been deployed around the stack, to seal the material of the cover on itself. , in particular by welding, facing the sixth face of the stack.

  • LDPE low density polyethylene
  • LDPE low density polyethylene
  • LDPE low density polyethylene
  • the placement of a stretch sleeve does not require a heat source, because it suffices to mechanically stretch the plastic film material in the transverse direction beforehand before wrapping the film. stacking of modules. After placing the stretched cover on the stack of modules, the tightening of the material of the stretch film occurs naturally by elasticity, which firmly holds the cover around the stack of modules.
  • the cover may be a shrinkable cover, formed from a sheath of heat-shrinkable plastic film, for example of heat-shrinkable polyethylene.
  • the second film is a plastic film having a higher tensile strength than that of the plastic film constituting the cover.
