  • Patent number: 10676809
    Abstract: According to certain embodiments, a method of producing a pattern on a substrate comprises securing a flexible polymeric substrate, printing a layer of ink as a negative pattern on the substrate, and placing the flexible polymeric substrate in a vacuum chamber. The method further includes uniformly applying, while the flexible polymeric is under a vacuum in the vacuum chamber, a layer of material over both the layer of ink and the substrate via physical vapor deposition and then removing the flexible polymeric substrate from the vacuum chamber. The method further includes removing the ink and material applied over the ink by immersing the flexible polymeric substrate in a solvent such that it results in a desired pattern of the material on the flexible polymeric substrate.

    Abstract: Unexpectedly unique and environmentally friendly composite material structures, storage articles fabricated therefrom, and related methods. The composite structure includes at least one or more fiber-containing layers, such as fiberboard or other layers having fibers from natural and/or synthetic sources, and one or more mineral-containing layers. The mineral-containing layer(s) comprises a thermoplastic bonding agent fixing the mineral particles in place. The fiber-containing layer(s) and mineral-containing layer(s) can be shaped, sized, and manufactured such that the composite structure formed therefrom is capable of being machined to form the storage article. The composite structure can be repulped and recycled without the use of dispersions, emulsions, or aqueous solutions. Further, the composite reduces layer mass requirements for heat seal, barrier, and fiber adhesion compared to polymer layers.

The method which has been developed creates a “value-added” product by the wastepaper supplier or at the pulp and/or deinking (recycled paper) mill—a wastepaper load/bale, wet pulp stock or wet lap, or dried pulp treated with or impregnated with enzymes that enhance the quality of the pulp or paper product when it is repulped and processed at the paper mill.

  • Publication number: 20120305206
    Abstract: A method for removing ink from printed paper comprising: (a) pulping printed paper at least 25 wt % of which is old newsprint at a consistency of at least about 3% to obtain a pulp slurry; (b) treating the pulp slurry with an ink removing system, which system comprises: (i) a combination of lipase and at least one second enzyme chosen from amylase, xylanase or cellulase, and (ii) a non-ionic surfactant, in amounts effective to release ink from said pulp slurry, wherein the lipase is present in an amount of at least about 0.001 wt % based on the dry content of the pulp slurry and the ratio of the at least one second enzyme:lipase is at least about 1.2:1; and (c) separating the released ink from the pulp slurry, wherein the treating step is carried out prior to a deinking flotation stage.

  • Patent number: 8317973
    Abstract: The present invention relates to cost-effective and environmentally friendly polyester surfactants containing a condensation esterification product of a polyhydric alcohol, a multimeric acid, and at least one polyalkylene glycol for use in flotation deinking under traditional alkaline, reduced alkali, and true neutral deinking conditions. The polyester deinking surfactants of the present invention will effectively exhibit greater selectivity than traditional flotation deinking surfactants. In particular, the polyester deinking surfactants can give better foam control, improved yield, and no loss in ERIC reduction.

  • Patent number: 8287690
    Abstract: The present invention provides methods for deinking printed waster paper—particularly methods that use a deinking composition that includes a hydrophobically-modified inorganic particle (“MIP”) to improve ink collection efficiency under traditional alkaline, reduced alkali, and true neutral deinking conditions. Deinking compositions are provided that include a hydrophobically-MIP substrate, a nonionic surfactant, and a fatty acid, or mixtures thereof. The improved ink collection of the present invention can result in deinked pulp of high quality and/or yields that has excellent brightness and effective residual ink concentrations (“ERIC”) values.
