In an aspect a method of manufacturing an acoustic floor panel is described. The method may include: combining a binding agent with plastic flakes; passing the plastic flakes and the binding agent to a lamination machine; applying a force to the binding agent and the plastic flakes using the lamination machine to create a plastic sheet; cutting the plastic sheet; and adding an acoustic insulator to at least a first side of the plastic sheet.

A recyclable paper laminate comprising a water-dispersible barrier against any permeation.

A biodegradable paper laminate comprising a water-dispersible barrier against permeation.

A multi-layered packaging film includes (a) an outer print layer, (b) an inner product-side layer, and (c) a lamination layer interposed between the outer print layer and the inner product-side layer.

A multi-layer biaxially oriented polyester (BOPET) film having at least one BOPET film layer and at least one coating layer comprising a polyester polymer and particles that are partially or fully embedded in the coating layer is described herein. The particles have an average particle size of about 4 to 8 microns, the coating layer has a gloss of 25 GU or less measured by a 60 degree glossmeter, and the paint adhesion crosshatch test value of the BOPET film as per ASTM D3359-09 is 10% or less.

The present invention relates to a process for preparing and compositions for stiffening materials for use in the manufacturing of footwear using a combination of stiffeners and adhesives.

The invention relates to a multi-layered structure intended for producing a packaging article for storage purposes and to a method for producing said structure. The essence of the invention is that a multi-layered composition based on foamed recycled polyethylene terephthalate comprises a printed layer, a layer of foamed recycled polyethylene terephthalate having a density of from 100 kg/m.sup.3 to 900 kg/m.sup.3 and an intrinsic viscosity of from 0.5 dl/g to 1.0 dl/g, and also a layer of polyethylene or a polyethylene copolymer, or a polyethylene terephthalate copolymer. A method for producing a multi-layered composition consists in cleaning polyethylene terephthalate waste, then grinding same into fractions, followed by melting it and subsequently extruding the melt, then producing granulated polyethylene terephthalate, then extruding the granulated polyethylene terephthalate, foaming the melt, subsequently cooling the foamed recycled polyethylene terephthalate, calendering it to a thickness of from 200 μm to 1000 μm.

An exemplary embodiment of the present disclosure provides a polyurethane core for use in a floor or wall panel, the core comprising a polyol made, at least in part, from one or more recycled materials, and an isocyanate.

Large volumes of recycled polyethylenes are available for reuse. It would be desirable to prepare films from recycled polyethylene, however, the technical demands for many types of films can make this very difficult. Provided herein are films, for example, stretch films; shrink films; films for vacuum packages and films for dunnage packaging, that may be prepared from a blend of recycled polyethylene with “virgin” polyethylene.

The present disclosure relates to a method for selecting a polyester film in which the polyester film is used as a sealant layer in a multilayer body including a base material layer including a crystalline polyester film, an adhesive layer and a sealant layer in this order, the method including:

a step in which FT-IR analysis is performed on the polyester film by a reflection method, and the crystallinity of the polyester film is measured by the following formula; and

a step in which a first polyester film having a crystallinity of 2 to 15% is selected:

I.sub.1409=p1×I.sub.1340+p2×I.sub.1370  (Formula 1)

Crystallinity[%]=p1×(I.sub.1340/I.sub.1409)×100  (Formula 2)
