Definitions

  • Barrier properties are typical performance requirements of packaging materials to prevent the premature deterioration of the packaged goods. It is highly desirable that packages for perishable liquid or dry foods be moisture-, oxygen- and aroma-proof for improving the durability of the product.
  • One known method for rendering paperboard packaging substrate impermeable to liquid and gas is to provide the board with a metal foil. This method, however, has several drawbacks, including high manufacturing costs, non-biodegradability of the foil layer, problems of regeneration of the packaging material, and the unsuitability of the packaging for heating in a microwave oven.
  • the structure consists of paperboards; a first heat- sealable polymer layer coated on one side of the paperboards; a polyamide layer laminated on the other side of the paperboard to impart mechanical strength, thermal resistance, and improved durability; a layer of EVOH copolymer laminated on the surface of the polyamide layer to provide oxygen barrier performance; a second heat-sealable polymer layer applied over the EVOH layer; and a tie layer between the EVOH layer and the second heat-sealable polymer layer.
  • U.S. Patent No. 6, 193,827 teaches a non-foil composite laminate having improved oxygen and flavor barrier that i is suitable as a packaging material for products such as fruit and citrus juices, beverages and the like, and non-liquid dry products.
  • the non-foil laminate is produced by applying a layer of heat-sealable olefin polymer on one side of the paperboard to provide one outer surface of the laminate; coextruding over the other surface of the paperboard substrate a sandwich layer comprising a first adhesive tie layer, an amorphous nylon layer and a second adhesive tie layer; and extruding a layer of heat-sealable olefin polymer over the sandwich layer to provide the other outer surface of the laminate.
  • these multilayer structures with enhanced barrier performance require successive incorporation of barrier layers and tie layers onto the paperboard substrate after the papermaking process.
  • the functional layers are applied, off-line from the papermaking process, onto the board using lamination or extrusion techniques. Accordingly, the production of these multilayer boards is rather complicated and costly.
  • Oxygen barrier films such as EVOH and nylon, are laminated off-line from the papermaking process.
  • the paperboard from papermaking process must be transported to a lamination site, unwound prior to lamination, and processed to give the final structure.
  • the commercial materials require several layers of costly barrier components to achieve the barrier level that is typically demanded for packaged goods sensitive to oxygen and water vapor.
  • WO 00/76862 teaches a laminated structure for packaging applications comprising a paper substrate and at least one polymer/nanoclay composite layer. Nanoclay particles are dispersed in a molten polymer matrix, and consequently the molten polymer/nanoclay composite is applied onto the paper substrate off-line from papermaking process, either through extrusion coating or extrusion lamination.
  • a method of making multilayer paper-based packaging materials with enhanced barrier performance is disclosed that is economical on a per- package cost basis.
  • the disclosed method comprises steps of coating a water-based barrier composition on-line during papermaking process onto at least one surface of the paper-based substrate, and then applying a polymeric film onto the surface of the resulting coated paper-based structure.
  • the disclosed method may include a step of applying a layer of base coat between the paper-based substrate and the barrier layer to enhance the surface smoothness and reduce the porosity of the paper-based substrate.
  • FIG. 1 shows one embodiment of the disclosed multilayer packaging material, comprising a paper-based substrate, a barrier layer derived from water- based barrier coating composition on one surface of the substrate, and a polymeric film layer applied over the barrier coating layer;
  • FIG. 2 shows one embodiment of the disclosed multilayer packaging material, comprising a paper- based substrate, a layer of base coat applied on one surface of the substrate, a barrier layer derived from water-based barrier coating composition applied over the base coat, and a polymeric film layer applied over the barrier coating layer; and
  • FIG. 3 shows one embodiment of the disclosed multilayer packaging material, comprising a paper-based substrate, a barrier layer derived from water- based barrier coating composition on one surface of the substrate, a first polymeric film layer applied over the barrier coating layer; and a second polymeric film layer positioned on the other side of the substrate.
  • the present method of producing multilayer paper-based packaging materials includes steps of:
  • water-based barrier coating compositions may be used in the present method.
  • the water-based barrier coating compositions may be applied onto the paper-based substrate by any known application methods. These include, but are not limited to, size press application, brushing, spraying, roll coating, rod- coatings, dipping, spreading, printing methods, air knife coating, and curtain coating. To reduce both production cost and complexity, the water-based barrier coating composition may be applied onto the paper-based substrate on-line during the papermaking process.
  • FIGURE 1 shows one embodiment of the multilayer paper-based packaging material produced from the presently disclosed method.
  • the multilayer packaging material 100 comprises a paper-based substrate 10, a layer of barrier coating 11 derived from a water-based coating composition, and a layer of polymeric film 12 on the outer surface of the barrier coating layer 11.
  • the polymeric film may be applied onto the barrier-coated structure by many known application techniques. These include, but are not limited to, lamination and extruded coating.
  • polymeric films suitable for use in the present disclosure include, but are not limited to, polyolefins such as polyethylene and biaxially oriented polypropylene; polyesters such as polyethylene terephthalate (PET) and biaxially oriented polyester film; polyamides such as nylon and metallocene catalyzed nylon; poly(ethylene- vinyl alcohol); polyvinylidene chloride; polyvinyl alcohol; lactic acid-based polymer such as polylactic acid (PLA); polyvinyl chloride; polyacrylonitrile; and combinations thereof.
  • PET polyethylene terephthalate
  • polyamides such as nylon and metallocene catalyzed nylon
  • poly(ethylene- vinyl alcohol) polyvinylidene chloride
  • polyvinyl alcohol lactic acid-based polymer
  • PLA polylactic acid
  • polyvinyl chloride polyacrylonitrile
  • the disclosed method further comprises a step of applying a layer of base coat formulation onto the substrate prior to the application of the barrier coating layer.
  • a layer of base coat formulation onto the substrate prior to the application of the barrier coating layer.
  • Any standard base coat formulation may be used in the present disclosure.
  • FIGURE 2 shows such embodiment, wherein the multilayer packaging material 200 comprises a paper-based substrate 10; a layer of the basecoat 13 applied on one surface of the substrate; a layer of barrier coating 11 applied over the basecoat 13; and a layer of polymeric film 12 positioned over the barrier layer 11.
  • the disclosed method of producing multilayer paper-based packaging materials includes steps of:
  • FIGURE 3 shows the multilayer packaging material 300 comprises a paper-based substrate 10; a layer of barrier coating 11 positioned on one surface of the substrate, a first polymeric film layer 14 positioned on the other surface of the substrate; and a second layer of polymeric film 12 positioned over the barrier layer 11.
  • the first polymeric film may have the same composition as the second polymeric film.
  • FIGURES 1 -3 are only to demonstrate some structural examples for the multilayer packaging material of the present disclosure. It is to be understood that one skill in the art may tailor the structure of multilayer product to provide the desired performance for the selected end use applications, without departing from the concept of present disclosure.
  • Oxygen transmission rate is the measurement of the amount of oxygen gas that passes through a substrate over a given period. In the present disclosure, the OTR was measured at 23 0 C and 0% RH using Mocon OXTRAN 35 2/20 or 2/60 modules. Each tested sample was loaded onto the modules and conditioned for 2 hours prior to the OTR measurement. Two controls were used for the study of the enhanced barrier performance of the presently disclosed multilayer paper- based packaging structure.
  • the first control was the uncoated paper-based substrate.
  • the second control was the paper-based substrate coated with a barrier layer derived from the same water- based barrier coating composition as that used for the multilayer structure of FIGURES 1 and 2.
  • the disclosed multilayer packaging materials have an excellent oxygen barrier performance that is suitable for packaging applications.
  • the disclosed multilayer packaging material may be designed such that its OTR is less than 100 cc/m 2 .day.atm as determined at 23 0 C and 0% RH using Mocon OXTRAN 35 2/20 or 2/60 modules.
  • the disclosed multilayer packaging material has an OTR value of less than 10 cc/m 2 .day.atm.
