摘要:
The invention relates to a method for coating a paper web (1), comprising the steps in the following sequence: applying a first layer (20) made of a predetermined quantity of melamine resin to a first side of the paper web (1), first drying of the thus coated paper web (1) at a web temperature of at least 120° C., applying a second layer (21) made of a predetermined quantity of urea resin to a second side of the paper web (1), and second drying of the paper web (1) at a web temperature below 100° C.

摘要:
A paper or paperboard web (W) is precalendered. A web that has undergone earlier dewatering stages is calendered to attain a suitable surface for the coating process. The web is calendered (C) one-sidedly in such a manner that the absorption level of the second side (W2) of the web entering the calendering, which is higher than the absorption level of the first side (W1), is reduced in the calendering nearly to the same level or at least to the same level with the first side (W1).
摘要:
A porous metal oxide material in a flake form having a specific surface area of 110 to 3000 m2/g, an average particle diameter of 5 to 500 μm, an average thickness of 0.1 to 5 μm, and an average aspect ratio of 5 to 300; a method for producing the material which comprises applying a colloid solution containing colloidal particles of the metal oxide having a particle size of 5 to 500 nm on a substrate, drying to solidify the colloid solution, delaminating the resultant solid form the substrate, and subjecting the solid to a heat treatment; and a cosmetic, a coating composition, a resin composition, an ink and a paper sheet comprising the material. The porous metal oxide material in a flake form exhibits functions inherent in a porous material, is free problems such as the reduction of handlability due to coagulation, has a great mechanical strength, and exhibits great holding capability when used as a carrier.
摘要:
An improved paperboard has been bulk enhanced by retaining a substantial portion of bulk-enhanced additives including expandable microspheres in a suitable distribution within the paperboard. The cellulosic paperboard web has an overall fiber weight (w) of at least 40 lbs. per 3000 square feet and, at a fiber density of 3, 4.5, 6.5, 7, 8.3, and 9 pounds per 3000 square foot ream at a fiberboard thickness of 0.001 inches, has a GM Taber stiffness of at least about 0.00246 w2.63 grams-centimeter/fiber mat density1.63, and a GM tensile stiffness of at least about 615+13.18 w pounds per inch. The high retention of the bulk enhancing additives is believed to result from the incorporation of suitable retention aids. The resulting paperboard has better GM Taber stiffness values and GM tensile stiffness than prior art paperboards. The paperboard also has increased strain to failure and is able to be formed into suitable paperboard containers without loss of integrity. The resulting containers have increased hold times when they contain hot or cold food or drink.
摘要:
A machine for single or double sided application of a liquid or viscous coating medium by way of at least one applicator unit onto the surface of a mating material web, especially a paper or cardboard web. A medium collecting device that is allocated to the applicator unit or to a dispensing component of the applicator unit which includes the dispensing openings, is equipped with a receiving and release component which is allocated to the medium collecting device and which is or can be mounted detachably on same. During the start of the application process the component releases the curtain or veil due to a common adjustment with the medium collecting device or of a section component of same relative to the curtain or veil from a rim extending across the moving background or from an edge extending across the moving background.
摘要:
A laminated packaging material (10) comprising a core layer (11) and a barrier layer (14) formed from a liqueform composition comprising a dispersion or solution of a polymer, starch or starch derivative on one side of the core layer, the barrier layer also including particles of amorphous SiO2. According to the invention, said particles of amorphous SiO2 in colloidal particle size in said barrier layer are present in a content of above 40 weight % but below 80 weight %. The invention also relates to a packaging container which has been produced from the packaging material, as well as a method of producing the packaging material.
摘要:
The present invention relates to a sheet having a rough surface feel on at least one of its sides, said sheet being coated on one or both sides with a layer comprising incompressible particles that are not flat and not very angular. It also relates to the process for manufacturing said sheet and to its use as a paper or plastic printing medium, a paper or plastic package, a cover intended for bookbinding, or a board or plastic box.

A printable recording material and the method of using the same. The material includes a substrate and at least one functional coating on at least one side of the substrate insuring printability. The coating includes a binder and inorganic pigments in an amount of at least 50% by weight based on the dry weight of the coating. An image can be embedded in the coating.
摘要:
A coating slip is applied to a first surface (SA) of a moving paper or board web using a gravity-based application method, the web's (W) direction of travel is turned by 120-200°, then a coating slip is applied to a second surface (SB) of the web using a gravity-based application method, and both sides (SA, SB) of the web are dried. The coating applicators include application beams (11, 16), which are located above the web and which have a supply gap or supply holes to pour out the coating slip with the aid of gravity on to the surface to be coated. At the run of the web (W) remaining in between these application beams (11, 16) turning devices (22) are fitted for changing the web's direction of travel by 120-200° after coating slip has been applied to the first surface (SA) of the web
