Definitions

  • multilayer packaging materials which include a paper or cardboard layer, and one or several layers of plastic or metal films, which provide robustness as well as barrier properties, especially to oxygen and moisture.
  • the cohesive strength of the polymer film is very high and the level of adhesion of the polymer to the paper or cardboard (i.e. cellulosic) substrate is also high. This prevents such polymer to detach from the substrate when recycled and prevents recycling and repulping of the cellulosic fiber portion in a paper-stream recycling process.
  • barrier properties are essential for maintaining the safety and quality of packaged foods.
  • barrier properties include gas barrier, for example to oxygen and water vapor (moisture), and if possible, also, liquid tightness.
  • PVOH polyvinylalcohol
  • EVOH ethylene vinyl alcohol
  • BVOH butenediol vinyl alcohol co-polymer
  • a vacuum deposited or transfer metallized inorganic layer comprising a metal, a metalloid, or a combination thereof, said inorganic layer having a thickness comprised between 1 and 100 nm, and
  • the overall thickness of polymer coating layers in the structure is extremely reduced compared to the thickness of paper material, therefore the inventors have achieved to overcome the technical limitations of the known multilayer barrier structures, and achieve a packaging multilayer structure with excellent barrier properties against oxygen and moisture transfer, as well as resistance to liquid contact from their inner or outer surfaces, while achieving a total contents of cellulosic fibres comprised preferably up to 95% of the overall material weight.
  • pre-coating polymer layer being water soluble promotes recyclability.
  • the resulting structure therefore demonstrates excellent repulping capabilities and high fibre yield which allows it to be accepted in paper waste collection in the most countries.
  • the biodegradable polymer used for said second organic layer is selected within the list of: a polycaprolactone (PCL), a thermoplastic starch (TPS), or polybutylene adipate terephthalate (PBAT).
  • PCL polycaprolactone
  • TPS thermoplastic starch
  • PBAT polybutylene adipate terephthalate
  • the inorganic layer is preferably selected within the list of: a metal, especially aluminium, or a metalloid, in particular aluminium oxide (AIOx), silicon oxide (SiOx).
  • the inorganic layer can also be made of an alloy thereof.
  • the multilayer material structure further comprises a third organic layer coated on the inner side of second organic layer, said third layer comprising a biodegradable polymer selected within the list of: polybutylene succinate-co-butylene adipate (PBSA) or polyhydroxyalkanoates (PHA) based polymer in an amount in the range of about 0.5-30 g/m 2 , preferably in the range of 1 to 15 g/m 2 .
  • PBSA polybutylene succinate-co-butylene adipate
  • PHA polyhydroxyalkanoates
  • extrusion lamination it is meant a similar process to extrusion coating, whereby a polymer resin is extruded between two substrates (e.g. a layer of paper and another layer of polymeric film), and acts as a bonding agent.
  • Dispersion coating it is meant a coating technique whereby an aqueous dispersion of fine polymer particles or polymer solution is applied to the surface of paper or board as such, in order to form a solid, non-porous film after drying.
  • Dispersion coating can be performed by gravure, flexo-gravure, rod, blade, slot-die, curtain air knife, or any other known method of paper coating.
  • Dispersion coating can create a much thinner layer than extrusion lamination and/or adhesive lamination, since the polymer is mixed in an aqueous water solution. This brings advantages in terms of quantity of polymer usage, its barrier performance and recyclability of resulting paper structure.
  • the target of dispersion coating is to achieve a barrier layer against water, water vapour, grease, oil, gas, etc. by environmentally friendly coating.
  • Another target is to prepare surface of paper material for a vacuum deposition process.
  • the multilayer packaging structure is preferably biodegradable in a soil or marine environment. Such a preferred biodegradability can be achieved when the structure contains a cellulosic base, an ultrathin inorganic layer that contains only a few atoms of metal or metalloid per square meter, and also because all polymeric components are biodegradable polymers.
  • Biodegradability of the final structure is defined and tested under international standard ISO 22403 ("Assessment of the intrinsic biodegradability of materials exposed to marine inocula under mesophilic aerobic laboratory conditions").
  • the multilayer structure according to the invention is also preferably designed to qualify for being as well recyclable in a paper stream process.
  • first organic layer comprises a polymer being water soluble, which makes it easier to separate the fiber from the rest of the structure, in particular from the cellulosic contents, - and finally, the subsequent organic layers (second organic layer, third, etc.), that are deposited on the inner side of the metallic or metalloid layer, feature low cohesion and low adhesion with the rest of the structure components, which makes the whole structure compatible with paper recycling processes as explained herein before.
  • first organic polyvinyl alcohol-based (PVOH) pre-metallization coating layer 3 that provides mainly gas (esp. oxygen) barrier properties and is applied as an aqueous solution in weight of 3 g/m 2 ,
  • PCL polycaprolactone
  • the innermost polycaprolactone layer 5 functions as a heat sealable layer in this first embodiment.
  • the structure 1 of this first embodiment achieves high moisture and gas barrier properties with values of Oxygen Transmission Rate (OTR) below 0.5 cm 3 /m 2 /day measured at 23°C and 50% relative humidity (RH), and water vapour transmission rate (WVTR) below 0.5 g/m 2 /day measured at 38°C and 85% RH.
  • OTR Oxygen Transmission Rate
  • WVTR water vapour transmission rate
  • PBAT is used as an alternative polymer to PCL
  • the polymer used in this case has a tensile strength measured at 40 MPa and its elongation at break is 1120%.
  • the multilayer structure comprises in order, from its outer side towards its inner side (i.e. the inner side in contact with the packaged product): - a highly smooth paper layer 2 of grammage 62 g/m 2 ,
  • a second organic layer 5 of polycaprolactone (PCL) polymer is applied as a first post-metallization on the inner side of the inorganic layer 4, as an aqueous dispersion in an amount of 5 g/m 2 .
  • PCL polycaprolactone
  • a third organic layer 6 of Polybutylene Succinate-co- Butylene Adipate (PBSA) polymer is applied onto the inner side of the second organic layer 5, which fulfils the role of a second post-metallization layer. It is applied as an extrusion coating, in an amount of 8 g/m 2 .
  • PBSA Polybutylene Succinate-co- Butylene Adipate
  • the second organic layer 5 of PCL functions as a tie layer between the inorganic layer 4 and the third organic layer 6 of PBSA.
  • the innermost PBSA based coating layer 6 functions as heat sealable layer in this second embodiment of the invention.
  • PCL can be replaced by TPS or PBAT polymers that feature tensile strength values above 30 MPa and elongation at break above 850%.
  • PBSA can be replaced by a polyhydroxyalcanoate (PHA) also having a thickness of 8 gsm.
  • PHA polyhydroxyalcanoate
