Bio-based polymers from raw lignocellulosic biomass
Disclosed herein is a method of making polymerizable bio-based monomers containing one phenolic hydroxyl group which has been derivatized to provide at least one polymerizable functional group which is an ethylenically unsaturated functional group (such as a [meth]acrylate group), where the precursors of the polymerizable bio-based monomers are derived from raw lignin-containing biomass. Also disclosed herein are bio-based copolymers prepared from such bio-based monomers and a co-monomer, and methods of making and using such bio-based copolymers. In particular, the bio-based copolymers can be used as pressure sensitive adhesives, binders, and polymer electrolytes.
PAPER ARTICLE COMPRISING A PAPER COMPONENT AND A HEAT-SEALABLE COATING
The present invention refers to a paper article comprising a paper component having a first side and a second side, wherein the first side and/or the second side of the paper component is at least partially coated with a heat-sealable coating, wherein the heat-sealable coating comprises a first polymer comprising units derived from a (meth)acrylate and/or (meth)acrylic acid and/or a salt thereof, and a second polymer, being different from the first polymer, comprising units derived from a) a (meth)acrylate and/or (meth)acrylic acid and/or a salt thereof, and b) an alkene, wherein the first polymer and the second polymer are present in the heat-sealable coating in a weight ratio of 90:10 to 35:65, and wherein the first polymer and the second polymer are present in the heat-sealable coating in an overall amount of at least 50 wt. %, based on the total weight of the coating. Furthermore, the present invention refers to a laminate comprising a paper component, a substrate and a heat-seal layer being present between the paper component and the substrate, which is obtained by heat-sealing a paper article according to the present invention to the substrate. The invention also refers to a use of a coating for heat-sealing a paper component to a substrate.
Non-sticking tipping paper, preparation method and application method of the same
A non-sticking lip tipping paper is disclosed that includes a base paper, a color layer and a surface coating. The color layer is formed by printing and drying a color ink on the base paper; the surface coating includes a water-based glue and is coated thereon after drying the color layer. The water-based glue includes the following components by weight: 30-65 parts of a modified water-based resin solution, 10-20 parts of water, 8-15 parts of ethanol, and 5-12 parts of a water-based additive. The water-based additive is a mixture of a wax emulsion and magnesium silicate in a weight ratio of 1:5. A preparation method and a method of applying the non-sticking lip tipping paper are also disclosed.
Recyclable liner for label assembly
In accordance with the present application, there is provided a release liner and method of preparing a liner for a label assembly. The release liner includes paper having a first side that does not have a machine finish or gloss finish or a coating; and a silicone treatment applied to the first side of the paper. The method of preparing a liner for a label assembly includes applying a coat of silicone to a paper at a side of the paper that does not have a machine finish or gloss finish and is otherwise uncoated; and curing the silicone. The release liner includes paper having a silicone coat weight of 0.5 lb/ream or less.
DENSITY ADJUSTABLE LABEL
The specification relates to a density adjustable label and a label laminate (8) for providing the same. Further, the specification concerns a combination of a label (1) and an item (100), as well as a method for manufacturing the label laminate (8). The label (1) comprises a face layer (2) and an adhesive layer (4). The face layer (2) comprises natural fibre based material. The adhesive layer (4) comprises pressure sensitive adhesive and at least one additive for adjusting total density of the label. The pressure sensitive adhesive comprises acrylic polymer(s). The additive comprises expandable particles, the label is detachable from a surface labelled at washing conditions having temperature in a range of 60-90° C. or above and the detached label is arranged to float on a washing liquid.
Segmented film adhesive, method of making the adhesive and method of applying the adhesive to a non-planar surface
A method of applying an adhesive to a non-planar surface. The method includes providing a segmented film adhesive. The segmented film adhesive comprises: (i) a liner; and (ii) an adhesive layer on the liner, the adhesive layer comprising a plurality of contiguous, discrete adhesive segments. The segmented film adhesive is positioned on a non-planar surface of a first adherend so that a first portion of the discrete adhesive segments are in contact with the non-planar surface and a second portion of the discrete adhesive segments are not in contact with the non-planar surface. The liner is removed from the non-planar surface, wherein only the first portion of the discrete adhesive segments remain on the non-planar surface of the first adherend.
Recycling compatible PSA label
A label which is attachable to object surfaces includes a pressure sensitive adhesive layer having a coat weight equal to or higher than 10 g/m.sup.2. The adhesive layer has a composition which is free of alkylphenol ethoxylate and has been selected to comprise emulsion polymerized, water-dispersible acrylate polymer and non-ionic copolymer based on polyethylene glycol and polypropylene glycol such that when the adhesive layer is subjected to paper recycling process conditions, the adhesive layer resists disintegration into small fragments.
