  • this condition of substantially full impregnation requires the absorption of at least 20% by weight of impregnant. As shown by the test results set forth hereinafter, such full impregnation prior to lamination results in outstandingly good WVT properties.
  • the other ply of the laminated material (usually buit not necessarily the outer ply of the package) comprises a suitable paper, in most cases a paper capable of being printed, in the range of 8-90 lbs. (basis 24 X 36-500: 3000 sq. ft.).
  • paper made from chemical pulps including sulphate papers, sulphite papers, sulphate-'sulphite combination papers, andV soda pulp papers, rtliese various papers being either uncoated'or coated on one' or both sides with a coating comprising clay, titaniumdioxide, and binder; papers made from chemical pulp or chemical pulp and groundwood combinations, coated or uncoated, which have been calen-Y dered or suplercalendered such as publishing papers, glassine, supercalendered sulphite papers, machine finish sulphite-sulphaite papers, and machine finish and machine glazed sulphite-sulphate papers; and other materials such as cellulosic films including cellophane and cellulose acetate, foil and the like.
  • the laminlant is applied to one or both surfaces to be laminated and .these surfaces are then juxtaposed in any suitable manner, with or withouit heat and/or pressure as may be appropriate to the particular impregnants and' laminants involved.
  • VVarious procedures and apparatus for laminating materials together are well known in the art and need not be set forth in detail. For quantity production, of course, it will be desirable to laminate strips or sheets running continuously over rolls, the larninantY being applied by spraying, dipping or brushing as may be most convenient.
  • Suitable laminants include, forexample,.microcrystalline waxes alone or with added polyethylene, butyl rubber, polyisobutylene, and/or parain;
  • paraffin polyethylene 200G-21,000 N. W.
  • vinyl acetate emulsions polyamides
  • butyl rubber emulsions and like moisture-proof adhesives.
  • the board which is to be impregnated and form the inner ply is drawn from any suitable sup-l ply, preferably in the form of a continuous web or strip 1, and passes through a suitable evacuated chamber 2 containing a bath 3 of hot liquid impregnant.
  • the strip is caused to move through the bath by means such as the guide rollers 4, 5, and 6, dipping under the surface of the bath and them emerging from the bath before leaving the evacuated chamber.
  • the desired moistureresistant adhesive is applied to the strip and distributed over its surface by any suitable means as indicated by the arrow 7. Then while the moving strip with its impregnant and adhesive is kept hot by heating means 8 disposed along the path of travel, the paper that is to form the outer ply is drawn from any desired source, preferably in the form of a continuous web or strip 9 which passes around a roller 10 intoa path parallel to that of the strip 1. The two strips 1 and 9 are then suitably pressed together, as by passing them between rollers 11, 12 completed, the laminated strip or web leaving the rolls at 12.
  • impregnated 8 pt. and 10 pt. bleached kraft board was laminated to a paper coated on both sides with clay and binder or with clay, binder and titanium dioxide (basis 25 x 38-500; equivalent to 54.5# per 3000 sq. ft.).
  • These kraft boards were imweb of the board through a vacuum chamber immersed in a bath of melted parain.-. vOne side of the board was then coated with Quaker State amber microcrystalline wax by means of a laboratory coating applicator, the temperature of the microwax being 2lO-230 F. and the impregnated board being heated to 220 F.
  • the fold used for WVT analysis consisted of creasing each sample four times. Two creases, one inch apart, ran in the machine direction; the other two were similar running in the cross direction of the board or perpendicular to the first two. One score in each direction was prebroken and the other two 180.
  • the invention Y provides a new packaging or cartoning material offering marked advantages in the packaging of goods requiring protection against loss of moisture to or absorption of moisture from the outside atmosphere.
  • the single laminated sheet is simplerl andeasier to handle than multiple prior cartons plus liners and/ or overwraps, both in packagingrthe lgoods by the manufacturer and in opening the packages for use of the goods by thelcustom'er.
  • the single laminated struc- 40 ture of this type was better than the/plain V(nonimpregnated) laminated structure 'and nearly 200% better than the standard.
  • the double-laminated impregnated material was much better than the single-laminated 45 impregnated material as would be expected.
  • a process for making laminated packaging material highly resistant to theV transfer -of water vapor therethrough which com-prises impregnating board which is to form one ply by forcing a moisture-resistantv impregnant amounting to at least 10% by weight of the board into the boardY under pressure so that the major portion thereof is absorbed by the board beneath its "surface, juxtaposing a flat ply of said board and a second ilat ply of paper, and laminating said previously impregnated board and paper together by interposing a moisture-resistant Vadhesive distributed over the. juxtaposed at faces of said plies and pressing the plies together.
  • a process for making laminated packaging material highly resistant to the .transfer of water vapor therethrough which comprises juxtaposing two at' plies, Aone comprising 5-40 point board in the range of ⁇ 20 160 lbs. weight per thousand square feet and previouslyirnpregnated with a moisture-resistant material amounting to at least 10% by weight of the board the major portion of which is absorbed into the board beneath its opposite surfaces-the other ply comprising paper in the 7- range of 8-90 lbs. weight per'threethousandsquare feet,
  • the method of making laminated cartoning material which comprises forcing parain under pressure into a sheet of approximately 8-10 point kraft board with 20- 35% by Weight of parain to form one ply, juxtaposing a at sheet of said board ply with a second at ply comprising a sheet of printing paper of approximately 8-90 lbs. weight per three thousand square feet, interposing rnicro-crystalline wax as an adhesive between the paper and previously impregnated board, and distributed substantially uniformly over their juxtaposed ilat surfaces and pressing them together while maintaining said parain in a molten condition during lamination.
  • a laminated packaging material comprising a ply of -40 point board in the range of 20-160 lbs. per thousand square feet in weight, said board being impregnated with a moisture-resistant impregnant amounting to at least by weight of the board and the major portion thereof lling the voids in the board beneath its opposite surfaces, a second ply comprising paper in the range of 8-90 lbs. per three thousand square feet in weight, :and a moisture-resistant laminating adhesive material interposed between said impregnated board ply and said paper ply, said plies being juxtaposed and adhesively united over their entire area by said interposed adhesive material.
  • a laminated packaging material comprising a ply of 5-40 point board in the range of 20-160 lbs. per thousand square feet in weight, said board being impregnated with a moisture-resistant impregnant amounting to at least 10% by weight of the board and the major portion thereof filling the voids in the board beneath its opposite surfaces, a second ply comprising paper in the range of 8-90 lbs. per three thousand square feet in weight, said paper being printed on one side to form the external surface of a package, and a moisture-resistant laminating adhesive material interposed between said impregnated board ply and the other side of said paper ply, said plies Ibeing juxtaposed and adhesively united over their entire area by said interposed adhesive material.
  • a laminated packaging material as defined in claim 8 said adhesive material comprising microcrystalline wax.
  • a laminated material for making moisture-resistant cartons comprising a ply of approximately 8-10 point kraft board impregnated with 20-35% by weight of paranic wax, the major portion of said impregnant filling the voids in the board beneath its opposite surfaces, a second ply of printing paper in the range of 8-90 lbs. Weight per three thousand square feet, said plies being joined throughout substantially their entire area by interposed microcrystalline wax as an adhesive.
