A multilayer film is described comprising a first film layer comprising an organic polymeric material, wherein the first film layer has an elongation of at least 250%; and a second film layer comprising a crosslinked polyurethane wherein the polyurethane comprises polymerized units of a polyamide. In some embodiments, the organic polymeric material of the first film layer comprises polyurethane. Also described is a method of protecting a surface of a motor vehicle and a method of making a multilayer protective film.

The present invention relates to a dehumidification bag and a preparation method thereof. The dehumidification bag comprises a bag body including a first side sheet and a second side sheet, the side sheet comprises an air-permeability and/or a composite film, wherein at least all or part of at least one side sheet is an air-permeability film; a moisture-proof layer covers the outside of the air-permeability. The dehumidification bag provided by the present invention provides an air-permeability on the bag body, and adopts heat sealing between the outer surface of the air-permeability layer and the moisture-proof layer, so that the air-permeability and the moisture-proof layer are in close contact without moisture absorption, which effectively prevents damage during transportation and storage. In the process, the air-permeability is in contact with the air in the outer bag and the effect of the dehumidifier becomes poor or invalid; by setting the moisture-proof layer to be tearable, when the buyer uses the dehumidification bag, the moisture-proof layer can be torn off, which is convenient and fast.

A composite fiber web having superior heat resistance and sound absorption and including a center layer containing a carbon fiber and a heat-resistant layer, and to a method of manufacturing the same. The method of the present invention can exhibit a fast manufacturing speed through a melt-blowing process that will generate economic benefits. The composite fiber web includes a composite layer and individual layers with various fiber diameters resulting in a superior sound absorption rate. The PET fiber included in the heat-resistant layer of the composite layer is an environmentally friendly material with superior heat resistance due to the inclusion of ultrafine fiber. Also, the composite fiber web has superior strength, conductivity, and electromagnetic shielding and deodorization effects, which allows it to be widely utilized for sound absorption materials and in all application fields thereof.

A gypsum wallboard having a core with a central core layer and one or more densified layers is disclosed. At least one densified layer contains salt absorbent particles of zeolite and/or hydrotalcite to improve adhesion of the gypsum core to a cover sheet. Also, methods of making the gypsum wallboard and a wall system for employing the gypsum wallboard are disclosed.

The invention relates to a formaldehyde-free binder composition for mineral fibres comprising at least one phenol and/or quinone containing compound, and at least one protein.

The invention relates to a method of bonding together surfaces of two or more elements, whereby at least one of the two or more elements is a mineral wool element, said mineral wool element(s) being bound by a mineral wool binder, the method comprising the steps of providing two or more elements; applying an adhesive to one or more of the surfaces to be bonded together before, during or after contacting the surfaces to be bonded together with each other; curing the adhesive, wherein the adhesive comprises at least one protein; at least one phenol and/or quinone containing compound, and/or at least one enzyme.

The present invention is directed to a flame-retardant building panel comprising a body having a first major surface opposite a second major surface, an inorganic coating atop the first major surface, the inorganic coating comprising a flame retardant component that includes a phosphate compound, and a metal complexing agent, wherein the phosphate compound and the metal complexing agent are present in a weight ratio ranging from about 50:1 to about 200:1.

A reduced weight, reduced density gypsum panel that includes high expansion vermiculite with fire resistance capabilities that are at least comparable to (if not better than) commercial fire rated gypsum panels with a much greater gypsum content, weight and density.

The present invention relates to a transdermal device including porous microparticles capable of containing an active principle, in particular nicotine, and to the use thereof as a drug, in particular for tobacco cessation. The present invention further relates to a method for preparing a transdermal device including porous microparticles filled with an active principle.

Provided is a printing-lamination inline system and method being suitable for manufacturing packages having various kinds of package designs in small quantity and being capable of performing inkjet printing and lamination in an inline manner. The printing-lamination inline system comprises: a first web-shaped base material supply unit configured to supply a first web-shaped base material; an inkjet printer of a single-pass system, which is configured to subject the first web-shaped base material to aqueous inkjet printing; an adhesive application unit configured to apply an adhesive to the first web-shaped base material subjected to the aqueous inkjet printing; a drying unit configured to dry the applied adhesive; a second web-shaped base material supply unit configured to supply a second web-shaped base material so that the second web-shaped base material is bonded to the first web-shaped base material; and a lamination unit configured to subject the first web-shaped base material and the second web-shaped base material to lamination.
