A manufacturing process of, and the relative laminated, polymeric semi-finished product are disclosed, the laminated, polymeric semi-finished product having in-depth aesthetic features, including at least two mutually welded layers by a lamination process with heat and/or pressure addition, wherein at least one of the layers is a thermoplastic material, in which the following steps are provided: providing a cohesion layer 100-500 micron thick, consisting of thermoplastic polyurethane, featuring in-depth aesthetic patterns; providing polymeric sheets with materials having a softening temperature above the one of the cohesion layer; and laminating at least one of the polymeric sheets at least partly transparent or translucent with the cohesion layer, by heat and/or pressure addition suitable to reach the softening of the cohesion layer featuring aesthetic patterns.

The present invention relates to a wrapped V-belt containing: a belt main body containing a compression layer containing a compression rubber layer and a fabric-laminated body layer, a tension rubber layer and a tension member buried between the compression layer and the tension rubber layer; and an outside cloth that covers a periphery of the belt main body, in which the compression layer has a plurality of notch portions not covered with the outside cloth, and the notch portion has a top disposed in the fabric-laminated body layer.

A method of making a sandwich-type composite panel having a cellulose-based core and a living hinge from a stack of material is provided. The stack includes first and second reinforced thermoplastic skins, first and second sheets of thermoplastic adhesive and a cellulose-based cellular core disposed between the sheets and the skins. A pressure is applied to the stack after heating the stack wherein the skins are bonded to the core by the sheets to form the composite panel. A portion of the composite panel is crushed at a predetermined location simultaneously with applying the pressure to locally compact and separate the cellular core at the predetermined location to form two side portions of the panel. The heated first skin stretches during the step of crushing while remaining intact between the two side portions. The skins bond together at the predetermined location to form the living hinge.

The invention provides protein adhesives, and methods of making and using such adhesives. The protein adhesives contain a protein-bonding agent and plant protein composition, such as an isolated water-soluble protein fraction or ground plant meal obtained from plant biomass. The protein-bonding agent can be an anhydride compound, carboxylic acid compound, carboxylate salt compound, or combinations thereof. The protein adhesives are useful in bonding together lignocellulosic materials and other types of materials.

The present invention relates to a barrier laminate comprising: a first cellulose substrate comprising highly refined cellulose fibers; a tie layer comprising a hot melt adhesive and a second cellulose substrate wherein the peeling strength between the second substrate and the tie layer is between 3-5 N. The present invention also relates to a method for manufacturing said barrier laminate.
