The present invention is directed to a process for manufacturing a nano-coated pulp-based substrate comprising the steps of: a) providing a suspension comprising pulp, said pulp having Schopper Riegler value of at least 70; b) using the suspension of step a) to form a wet web; c) dewatering and/or drying the wet web to form a substrate; d) adding a first layer of an acrylic monomer solution comprising less than 2 wt-% water to the surface of the substrate, followed by radiation curing the first layer; e) optionally adding a second layer comprising an acrylic monomer solution to the surface of the cured first layer and radiation curing the second layer; f) providing a nano-coating on the surface of the cured first or second layer such that a nano-coating having a thickness in the range of from 0.1 nm to 100 nm is provided on the substrate.

The present invention relates generally to the field of polymer dispersion coated, paper-based flexible packaging materials. In particular, the present invention relates to improving the barrier properties of polymer dispersion coated 5 paper-based flexible packaging materials. Embodiments of the present invention relate to a process for improving the barrier properties of polymer dispersion coated paper-based flexible packaging materials comprising the step of applying an Al2O3 coating to at least one surface of the dispersion coated paper-based flexible packaging materials, for example by using atomic layer deposition; and an Al2O3-coated paper material 10 obtainable by such a process.

The present invention is directed to a marine biodegradable and recyclable multi-layer metallized paper-based packaging material comprising a layered arrangement of superimposed organic and inorganic materials for providing barrier to oxygen and moisture: the organic and inorganic layers are made of materials which are selected for their marine biodegradable properties. In one embodiment of the present invention the multi-layer metallized paper-based packaging material can be recycled with other paper packaging materials.

The disclosure provides a decorative sheet having a low gloss and imparting a smooth feel. There is provided a decorative sheet including a primary film layer, and a surface protective layer provided to one side of the primary film layer, wherein the surface protective layer has a surface provided with an uneven structure including a plurality of ridge portions each protruding in a ridge-like shape; the uneven structure of the surface protective layer have a protruding peak height Rpk of less than 3.5 m; and an absorption spectrum obtained from Fourier infrared spectrometry of the surface protective layer has a ratio I.sub.1095/I.sub.1725 of 0.65 or more, that is a ratio of a maximum value I.sub.1095 in the wavenumber range of 1085 to 1105 cm1 to a maximum value 1725 in the wavenumber range of 1715 to 1735 cm.sup.1.

The disclosure relates to ethylenic polymers containing repeat units having pendant groups that can be linked to an ethylenic backbone via ester groups, such as those resulting from vinyl alkanoate monomers and alkyl (meth)acrylate monomers. The ethylenic polymer generally includes first repeat units in combination with one or more of second repeat units, third repeat units, and fourth repeat units. The first repeat units can include vinyl alkanoate monomer residues, the second repeat units can include alkyl (meth)acrylate residues, the third repeat units can include pendant carboxylic groups, and the fourth repeat units can include pendant aromatic groups. The combined structure of the ethylenic polymer is suitable for the formation of high-solids aqueous emulsions or dispersions, which can be used to apply a waterborne coating to a substrate such as paper. The ethylenic polymer and coatings therefrom can provide good water resistance, good oil resistance, recyclability, repulpability, and/or biodegradability.
