A method to produce a panel unit, including providing a core having a first surface and a second surface opposite the first surface, applying a surface layer to the first surface of the core, the surface layer including a wood veneer layer and a first binder layer for adhering the wood veneer layer to the first surface of the core, applying a balancing layer to a second surface of the core, the balancing layer including an unimpregnated paper and a second binder layer for adhering the unimpregnated paper to the second surface of the core, applying pressure to the surface layer, the balancing layer, and the core to form a panel unit. The disclosure also relates to a panel.

The present disclosure provides a method of enhancing the shelf-life of an activated surface of a thermoplastic material, including: coating at least a portion of a surface of the thermoplastic material with at least one adhesion promoter to provide a coated surface; and treating the coated surface with plasma to provide the activated surface of the thermoplastic material; wherein the activated surface has a contact angle in the range of from about 0 to about 40°; and wherein the presence of the at least one adhesion promoter is effective to maintain the contact angle in the range of from about 0 to about 40° for a time of about 10 days or greater.

The invention discloses a paperboard for packaging of a heat-sealable packaging material comprising: —a paperboard substrate comprising a first and a second side, —a first and an optional second dispersion coating layer on the first side, which first and optional second dispersion coating layer provides a barrier against at least one of liquid, moisture, grease and gas, —an extrusion coated barrier layer comprising a polyolefin, wherein the first and optional second dispersion coating layer is applied between the paperboard substrate and the extrusion coated barrier layer, and wherein the coat weight of the extrusion coated barrier layer is less than 15 gsm. The packaging material according of the invention minimizes the amount of plastic coating, but still provides the needed barrier properties for the packaging of food and/or liquid. The packaging material has especially been shown to provide a longer shelf life for food items packed in a packaging made from the material. Especially, the packaging material provides gas-, liquid and/or grease barrier properties. Although the packaging material comprises such low amount of extruded thermoplastic polymers, the material is readily heat-sealable.

Textiles are re-cycled by grinding and scatter-laying onto a needle-punched web optionally containing low-melting material, followed by laying a second needle-punched web over the scattered layer and re-needling the three layers before applying heat or heat and pressure to activate the low-melting ground material present within the layers. Additional low-melt ground material is optionally blended into the ground textile if low melt components are absent or insufficient to bond the composite. The ground material is driven and dispersed into the surrounding web layers with at least part of the material being adjacent the two outer surfaces. The physical properties of the composite can be adjusted by selecting suitable combinations including but not limited to needling stroke depth, needling density, needle gage, low-melt content, heat finishing conditions, and relative layer weights. The final composites can optionally be reintroduced into the original end use and include significant percentages of recycled material.
