The invention relates to a process for manufacturing a gypsum slurry by bringing together and mixing gypsum, water, wax powder and optionally other components, applying the gypsum slurry in a process for manufacturing a gypsum product and a gypsum product such as a plasterboard or wallboard obtained by the process and the use of the wax powder for the manufacturing of a moisture resistant gypsum product.

A drawable adhesive tape and a drawable adhesive tape product. The drawable adhesive tape includes: a base framework extending along length direction of the drawable adhesive tape and having a plurality of adhesive-accommodating regions which extend along both thickness direction of the drawable adhesive tape toward interior of the base framework and length direction of the drawable adhesive tape and which are arranged at intervals along width direction of the drawable adhesive tape, and an adhesive layer filled in the adhesive-accommodating regions. The drawable adhesive tape product includes a release paper and the drawable adhesive tape, in which, a surface of the drawable adhesive tape where the adhesive-accommodating regions are located is covered by an oily surface of the release paper. The drawable adhesive tape and drawable adhesive tape product have improved tensile strength and improved adhesion strength.

A multi-use adhesive tape including a first backing layer, a first adhesive layer on at least part of a surface of the first backing layer, a second backing layer and a second adhesive layer on at least part of a surface of the second backing layer. The second adhesive layer is releasably engaged with the first backing layer and the tape is configured so that the tape can be applied to an article using the first adhesive layer and, after removal from the article, the first backing layer can be removed so that the second backing layer can be applied to the article using the second adhesive layer.

Multi-layer composite material, production and use thereof A multilayered composite material comprises as components: (A) a sheet material, (B) a material capable of absorbing water or aqueous fluids, (C) at least one bonding layer and (D) a polyurethane layer with capillaries passing through the entire thickness of the polyurethane layer,
wherein the polyurethane layer (D) comes into direct contact with sheet material (A) or absorption-capable material (B) in one or more places.

Closure device includes a closure cap, which can be screwed onto the threaded connection of a container, forming a fillable capsule that is open at the bottom, on which a seal directed downward is sealed. Upper side of the part of the closure cap which forms the capsule is designed to be deformable and can be pressed axially downward. A press element is molded on this cover of the closure cap at the bottom. By pressing the cover downward, the downward-directed seal of the capsule is broken open by the press element. Seal is made from a laminate comprising a carrier material with a thickness of at least 0.5 mm. Subsequently, a barrier film is sprayed or laminated on the carrier material. The crimping forms a circumferential edge, by means of which the seal can be sealed to the capsule edge, on the inner side of the carrier material, with respect to the capsule, and resting on same. The carrier material has pre-notches in the form of cuts, which approximately cut through the carrier material yet leave the attached films intact.

This invention relates to a method for forming a panel or skin for a hollow core door, a method of manufacturing a said door, a hollow core door, a panel, and an apparatus for forming a panel and skin for a hollow core door. The method comprises providing a substrate comprising a patterned groove therein; applying a laminating material on the substrate with an adhesive. The method then comprises sealing the substrate with the laminating material thereon in a chamber and providing at least one deformable membrane adjacent the laminating material; removing air from the chamber wherein under vacuum, the deformable membrane deforms into the groove thereby urging the laminating material into the groove; heating the laminating material to facilitate bonding thereof to the substrate; and allowing the substrate with the laminating material thereon to cool so as to form a panel with the laminating material bonded thereto.

In a pressure auto-adjusting package for a heated food and a composite membrane thereof, the composite membrane includes a first membrane coated with a partial release layer thereon in a predetermined width, a second membrane provided with a cutting line corresponding to the partial release layer, and a glue layer disposed between the first membrane and the second membrane to glue the first membrane and the second membrane together, the first membrane and the second membrane are pseudo-glued at the position of the partial release layer, the cutting line of the second membrane is disposed at a heat seal opening and extends to the accommodating space. The package has a pressure generated therein when being heated, the pressure enters into a pseudo-glued area between the second membrane and the first membrane from the cutting line to form a gap where the pressure is released to prevent explosion.

A laminate vial includes a first laminate sheet including an outer paper layer and a middle barrier layer joined with the outer layer, the middle barrier layer joined with an inner layer formed of a plastic material. Also included is a second laminate sheet including an outer paper layer and a middle barrier layer joined with the outer layer, the middle barrier layer joined with an inner layer formed of a plastic material. The first laminate sheet is joined to the second laminate sheet to define a seal and a cavity. Recycled materials may be used in all of the layers of the laminate.

Compounds useful for formulating inks, 3D printing resins, molding resins, coatings, sealants and adhesives which exhibit reduced shrinkage stress and high hardness and stiffness when cured are described which include a single free radical-polymerizable functional group, one or more urethane and/or ureido linkages and one or more cyclic structural elements per molecule.

A method for making labels comprising providing a plastic substrate layer and a paper substrate layer. The paper substrate layer comprises a printed display information sheet, wherein the printed display information sheet comprises a plurality of display information tags arranged in an array. The plastic substrate layer is coupled to each of the rows of display information tags within a first portion of the display information tags to form a composite substrate row. A first line of perforations is cut into a width of the composite substrate at one or more first spaced intervals, a length of the first spaced intervals being defined by a length of the display information tags. A second line of perforations is cut into a width of the composite substrate at one or more second spaced intervals, a length of the second spaced intervals being defined by a height of the display information tags.
