    Abstract: A sheet of material that substantially reduces or eliminates the incidence of bleed-through and show-through, thereby enabling a user to prepare artwork, sketches, designs, etc. on both sides of the sheet of material, without the incidence of bleed-through or show-through. The sheet of material comprises a first substrate, a second substrate, and an adhesive material positioned between the first substrate and the second substrate. The adhesive material operatively joins the first and second substrates to each other. The adhesive material acts as a moisture barrier, thereby preventing ink or moisture from passing therethrough and saturating the second substrate when ink or moisture is applied to the first substrate and vice versa. The adhesive also serves as a light barrier, thereby reducing or eliminating show-through on the second substrate when ink or moisture is applied to the first substrate and vice versa. Multiple sheets of material may be bound into a sketch book or a sketch pad.

  • Publication number: 20100167074
    Abstract: Adhesives are uniquely formulated to ensure appropriate adhesion to polymer coated paperboard. Such adhesives can be used in case and carton sealing applications and other applications using the coated paperboard stock material. The coatings can often pose problems for adhesives designed to adhere to the coated surfaces. The adhesives of the invention form adequate adhesive bonds to the coated corrugated paperboard such that the paperboard can be adhered to other substrates or to itself in case and carton sealing purposes. Coated paper board or coated corrugated board stock is commonly used in packaging materials where the package is exposed to extremes of temperature, humidity or liquid moisture. The coatings are used in packaging materials to withstand sufficient amounts of moisture such that the strength of either the adhesive used in the manufacture of the paperboard or the cellulosic base material of the paperboard are not compromised.

  • Patent number: 7514137
    Abstract: A packaging laminate for a retortable packaging container or carton, comprising a core layer (11) and outer, liquid-tight coatings (12 and 13) on both sides of the core layer (11). The one (12) of the two outer coatings carries decorative artwork (14) of printing ink which is both mechanically and thermally protected by a layer (18) of lacquer applied on the coating (12) to make possible heat treatment at high humidity and temperature conditions of a packaging container produced from the packaging laminate (10), without the printing ink decorative artwork of the packaging container deteriorating in quality.

  • Patent number: 7507473
    Abstract: A unique primer emulsion chemistry yields excellent adhesion of polyethylene terephthalate (PET)resin to clay coated paperboard (with high starch content) at reduced coatweights of the primer emulsion and the resin as compared to other primer and tie-resin chemistries currently employed for moisture barrier applications. A primer used for adhesion enhancement is an ammonium catalyzed, self-crosslinking copolymer of ethylene-vinyl acetate with N-methylol acryl amide functional groups attached to a polymer backbone. Use of the primer in amounts up to about 0.5 pounds per ream permits PET coatweights of as low as 10-12 lbs per ream and lower for some applications.

    Abstract: Heat-sealable, multi-layer composite packaging structures that are suitable for packaging and having improved sealing properties and simplified construction as compared to prior art composite film constructions are disclosed. The inventive film structure includes a first substrate, such as paper, bonded such as by extrusion lamination, to a sealable, high-barrier film. This inventive “paper-adhesive-polymer” lamination may replace prior art “paper-adhesive-foil-adhesive” foil-based tandem laminations. An improved or comparable polymer film substrate may replace the “foil-adhesive” layer components of the popular incumbent prior art structure.
