Definitions

  • This invention relates to packaging materials, and more particularly to a packaging material having grease resistance.
  • Grease resistant packaging with a metallic appearance has traditionally been obtained by several methods.
  • One option is to apply a fluorochemical to the backside of the paper substrate and then print using metallic inks.
  • the fluorochemicals and metallic inks are both expensive.
  • Another option has been to laminate aluminum foil to the fluorochemical-treated paper or grease-resistant parchment and then print the foil using well-known techniques. This latter technique is popular for stick margarine wrap.
  • Another option is to use aluminum foil wrap with an outer paper print ply or to use a paper-aluminum foil laminate. This technique is popular for chocolate bars and candies.
  • a metallized fluorochemical-treated paper was introduced for use in the pet food market as an attractive, lower-cost, easier to handle option to foil. The use of fluorochemical- treated paper still makes this an expensive packaging material. It is an object of this invention to provide a lower-cost grease-resistant metallized packaging material.
  • the metallized packaging material of the present invention has grease resistance provided by the coatings applied to the substrate.
  • the grease resistant packaging material comprises a paper substrate and at least one base coating layer overlying one surface of the paper substrate.
  • a layer of metal is provided overlying the base coating layer or layers, and a top coating layer is provided overlying the metal layer.
  • At least one of these coating layers is formed of a grease resistant polymeric coating formulation.
  • a coating layer is considered "grease resistant" if it passes the Grease/Oil Penetration test as defined herein.
  • the grease resistant coating formulation may suitably include an acrylic polymer and a polyethylene and/or polypropylene wax.
  • the grease resistant coating formulation may also be comprised of polyester polymers, polypropylene, polyethylene, or a polypropylene/polyethylene blend.
  • the opposite side of the paper substrate may optionally have one or more coating layers, which may either be a grease resistant formulation or a non-grease resistant formulation.
  • a standard paper substrate is coated with two coatings prior to metallization. These coatings can be solvent- based and/or water-based. They can be the same or different in formulation. Grease resistance is incorporated into at least one of these coatings. A thin layer of aluminum is vacuum deposited (or can be processed as transfer metallization) onto these coatings. A top protective and printable coating is then applied.
  • This top coating can be solvent-based and/or water-based.
  • the top coating may also be grease resistant if the application requires it.
  • the top coatings are typically vinyl-, olefin-, acrylic-, SBR or polyester-based, but other resin types are not excluded.
  • the drawing figure is a cross-section of a grease resistant sheet packaging material in accordance with the present invention.
  • a grease resistant sheet packaging material in accordance with the present invention is shown schematically in cross section in the drawing and is indicated generally by the reference character 10. It includes a paper substrate 11 with multiple coating layers overlying one surface of the paper substrate.
  • the paper substrate 11 preferably has a basis weight of from about 20 to about 144 pounds per ream, and may be selected from any of a number of conventional paper types or grades, including coated or uncoated printing grade paper, bleached and unbleached kraft paper, hardwood pulp paper, softwood pulp paper, beater dyed paper, groundwood pulp paper and sulfite pulp paper.
  • the paper is a clay coated print grade paper.
  • first base coating layer 12 which may be applied as a solvent-based polymer solution or a water-based polymer dispersion.
  • Suitable coating formulations for this first base coating layer include but are not limited to vinyl polymers, such as polyvinyl acetate, acrylic polymers, styrene-acrylic polymers, and styrene butadiene polymers. These coating formulations may or may not have resistance to grease and oils.
  • a second base coating layer 14 overlies the first base coating layer 12, and is formed of a coating formulation having resistance to grease and oils.
  • Suitable coating formulations for this second base coating layer include but are not limited to vinyl polymers, such as polyvinyl acetate, acrylic polymers, styrene-acrylic polymers, styrene butadiene polymers, and polyester polymers.
  • One preferred coating formulation comprises a water-based emulsion or dispersion of an acrylic polymer, together with polyethylene and polypropylene wax, and a silicone antifoam agent.
  • the coating formulations for base coating layers 12 and 14 may additionally include pigments or mineral fillers, such as, but not limited to, aqueous dispersions of clay, calcium carbonate or mica.
  • pigments or mineral fillers such as, but not limited to, aqueous dispersions of clay, calcium carbonate or mica.
  • Other additional components of the coatings may include thickening agents, defoaming or antifoaming agents, pigments, and crosslinking agents.
  • a metal layer 16 overlies and adheres to the second base coating layer 14.
  • the metal layer 16 may be suitably applied by vacuum metallizing, although other conventional methods could also be employed, such as transfer metallization.
  • the metal layer preferably has a thickness of at least 12 nm (optical density of 2.0) and may be formed of aluminum or other suitable metal.
  • a top coat layer 18 overlies the metal layer 16.
  • the top coat layer is also formed of a coating formulation having resistance to grease and oils.
  • One preferred coating formulation comprises a water-based emulsion or dispersion of an acrylic polymer, together with polyethylene and polypropylene wax.
  • the coating layers 12, 14 and 18 are each preferably applied at a coating weight within the range of from 0.5 to 15 grams per square meter, more preferably within the range from 0.7 to 5 grams per square meter.
  • the opposite side of the paper substrate 11 optionally has one or more coatings (not shown) overlying it. At least one of these coatings may be selected to have grease resistance.
  • the coating may be applied as an extrusion coating or a solvent-based polymer solution or a water-based polymer dispersion. Suitable coating formulations include but are not limited to vinyl polymers, such as polyvinyl acetate, acrylic polymers, styrene-acrylic polymers, styrene butadiene polymers, polypropylene, polyethylene, or a polypropylene/polyethylene blend.
  • Polymer formulations suitable for forming the grease resistant coating layer or layers include acrylic polymers or copolymers, preferably blended with one or more waxes selected from the group consisting of polyethylene wax, polypropylene wax, paraffin wax, and mixtures of these waxes.
  • Other grease resistant polymer formulations may be ethyl acetate, polyesters, polyolefins, such as polypropylene, polyethylene or a polypropylene/polyethylene blend, which may suitably be applied by extrusion coating.
  • Other grease resistant formulations may be based upon a polyester polymer or polymer blend or upon a styrene butadiene resin.
  • Grease resistant additives including, but not limited to starches and fluorochemicals may be included in the coating formulation.
  • the coating composition used for the first base layer 12 is a polyvinyl acetate such as Sun Chemical CJX-4900 or CJX-6587.
  • the second base layer 14 contains from about 15 to about 35 parts by weight of a styrene-acrylic polymer such as SC Johnson SCX-660 or SCX-1695 or Morton 61x105 or Cork FP6950 which have heat resistance built into the polymer structure, from about 0 to about 10 parts by weight of a polyethylene and/or a polypropylene wax such as SC Johnson Jonwax 22, 26, 28, 39 and 120, and from 0 to about 2 parts a fluorochemical such as 3M FC807 or FC845.
  • the formulation is also included in the formulation but are not essential to the grease resistance of the formulation. These components are dispersed in water to form a dispersion, preferably of about 20% to 30% solids.
  • the coating composition used for the top coat layer 18 is similar, except that the fluorochemical is omitted.
  • the above-described formulation of the second base layer 14 is used for both the first and second base coat layers, 12 and 14.
  • Another specific embodiment utilizes said formulation for both base coat layers, 12 and 14, and the top coat layer, 18.
  • the first base layer 12 is a polypropylene/polyethylene blend extrusion coated onto the paper substrate 11.
  • the second base coat layer 14 is omitted, and the metal layer 16 overlies and adheres to the first base coat layer 12.
  • the top coat layer 18 is not grease resistant.
  • a grease resistant layer is coated onto the reverse side of the paper substrate 11.
  • This grease resistant layer is comprised of 3-30 pounds per ream, more preferably 8-15 pounds per ream of a polypropylene/polyethylene blend that was extrusion coated onto the paper substrate.
  • Base coating layers 12 and 14, metal layer 16 and top coating layer 18 are not grease resistant.
  • base coating layer 12 is a water-based, grease resistant dispersion comprised of 25-75 parts, preferably 45-55 parts, Dow 681 (a SBR resin), 5-50 parts, preferably 20-30 parts Grain Processing Corporation Coatmaster ® K580 starch, and 0-75 parts, preferably 20-30 parts, Kaowhite clay slurry, plus additives known in the art for stabilization.
  • the second base coating layer 14 and the top coat layer 18 are not grease resistant.
  • Grease resistance may be measured using the 3M Kit test. This involves exposing the substrate to solutions containing varying amounts of castor oil, heptane and toluene. This test is generally published under the designation TAPPI UM557, incorporated herein by reference. To determine the grease resistance rating of a particular coating layer, the procedure is run on an individual coating layer formed of the polymeric coating composition. The grease resistance rating of the overall coated substrate is determined by conducting the same procedure on the coated substrate.
  • 3M Minnesota Mining and Manufacturing Co., St. Paul, Minn.
  • the kit includes twelve small bottles for use during testing and equipped with droppers or rods for application of solutions to the substrate to be tested. Also needed for conducting the test is absorbent cotton or tissue and a stopwatch or timer.
  • the bottles contain three reagents (Castor Oil, C.P. Grade; Toluene, C.P. Grade; and Heptane, C.P. Grade) in varying proportions.
  • Mixtures of these reagents are prepared according to the table above.
  • the reagents should be measured individually, rather than by addition since there will be loss of volume upon mixing.
  • Five representative specimens of suitable size (at least 2 by 2 inches or 5 by 5 cm) are obtained. Each test specimen is placed on a clean flat surface, test side up, being careful not to touch the area to be tested. From a height of about one inch (2.5 cm), a drop of test solution from one of the Kit Number testing bottles is dropped onto the specimen. Start a stopwatch as the drop is applied.
  • Kit Rating is the highest numbered solution that stands on the surface of the specimen for 15 seconds without causing failure.
  • the average Kit Rating of five specimens is reported to the nearest whole number.
  • This same procedure can also be used to test for resistance to a particular oil or greasy substance. If an oil or greasy substance is being tested, zero damage is considered a pass.
  • a substrate is required to be undamaged by kit solutions 1 through 7 or undamaged by the particular oil or greasy substance tested in order to be considered “grease resistant” according to this test procedure.
  • at least one of the coating layers in the overall coated substrate is undamaged by all twelve solutions. This superior performance indicates that these metallized papers should be suitable for use in other applications where grease resistance is needed, such as oil can labels, margarine wrap, other food wrap, personal care product labels, etc.
