The invention relates to a method of producing a laminate paper product comprising at least two layers, said method comprising (i) providing an aqueous suspension comprising cellulosic fibers (ii) adding to the suspension microfibrillar polysaccharide in an amount to yield from about 0.05 to about 50 wt % based on the weight of the cellulosic fibers (iii) dewatering the obtained suspension and forming a first layer having a density from about 150 to about 500 kg / m3 of said laminate paper product. The invention also relates to a method comprising (i) providing an aqueous suspension comprising cellulosic fibers (ii) adding to the suspension microfibrillar polysaccharide in an amount to yield from about 0.05 to about 50 wt % based on the weight of the cellulosic fibers (iii) dewatering the obtained suspension and forming at least a first and a second layer of said laminate whereby at least one of said at least first and second layer is formed from an aqueous suspension obtained in step (ii) containing microfibrillar polysaccharide; and joining said layers in such way that the laminate product obtains a density from about 150 to about 800 kg / m3. The invention also relates to a laminate paper product which can be obtained by the method and the use thereof.

Plies of paperboard are laminated to form a paperboard laminate having a front and a back. An automobile part is placed on the front of the paperboard laminate leaving exposed the front of the paperboard laminate. The automobile part and the exposed paperboard laminate are shrink-wrapped with plastic shrink-wrap material. For automobile window glass, some of the front side plies of the paperboard laminate have been cut out to form a cavity in the configuration of the glass product being packaged. The glass product is disposed in the cavity and a glass product conforming reinforcing block is placed against the backside of the paperboard laminate during the shrink-wrap operation. For automobile fenders, hoods, the paperboard laminate need not be cut out and the sides of the paperboard laminate are folded upwardly to form a carton bottom to which a lid is affixed for shipping.

A closing device located on a container of laminated paper, over a predetermined opening. The device has a lower part with a pouring opening and a cover closing the opening. A push-piece for breaking open the predetermined opening is provided in the lower part. The push-piece is joined to the lower part by a snap hinge, making the device more user-friendly and ensuring that the laminated paper predetermined opening does not obstruct the pouring opening area.

The invention relates to an industrial container (1) to be used as an envelope to protect the perimeter of the block formed by multiple panels (Cp) packaged into the container (1), for example flat glass panels or panels of other materials to be transported in the vertical position; the container comprises a framework (Qd) formed by a set of modular troughs (Cm), including an upper trough (Cm1), a lower trough (Cm2) and a pair of identical side troughs (Cm3), which are essentially composed of longitudinal profiles (2) with a U-shaped cross-section and a narrow width (x) for receiving a multiple panels (Cp); these profiles (2) are made of laminated paper or another suitable material, the profiles (2) of the upper trough (Cm1) and lower trough (Cm2) comprising reinforcement zones (3) for binding by means of strips (FT), the reinforcement zones (3) being formed by the juxtaposition of pairs of steel plates (3a) on the flat surface (2a) of the longitudinal profiles (2), while the longitudinal profiles (2) of each side trough (Cm2) also receive a protection cover (4) that has a U-shaped cross-section and is made of steel; the flat inside surface (2b) of the profiles (2) of the modular troughs (Cm) receives internal supports (5) for accommodating and protecting the peripheral edges of the multiple panels (Cp) packaged inside the framework (Qd).

An absorbent laminated paper article in the form of a rectangular sheet has first parallel edges in a first direction and second parallel edges in a second direction perpendicular to the first direction and an article area delimited by the edges. The article includes at least two plies adhesively bonded together in a bonding pattern between the plies. The bonding pattern includes bonding elements arranged along a first set of bonding lines extending from one of the first parallel edges to the other of first parallel edges in a first general direction at a first angle to the first direction and along a second set of bonding lines extending from the one of first parallel edges to the other of first parallel edges in a second general direction at a second angle to the first direction, the first set of bonding lines intersecting with the second set and forming an intermeshing network of bonding lines.

The invention provides a preparation method of a high-light-resistant titanium dioxide pigment for laminated paper. The method comprises the following steps: preparing titanium dioxide slurry from a rutile-type titanium dioxide initial product prepared by adopting a chlorination process method, and adjusting the pH value to 8.5-10.5; adding a citric acid radical-containing organic substance as a dispersing agent, and performing grinding treatment; performing heating to 55-65 DEG C for coating treatment, performing coating by using a dense aluminum phosphate coating layer, performing coating byusing a loose silicon aluminum compound coating layer, and performing coating by using a loose boehmite-type hydrated aluminum oxide coating layer; performing washing by using deionized water until conductivity of a filter cake is greater than 15000 omega*cm, and performing drying; and adding amino-containing organic matter in the steaming powder process, and performing organic coating treatmentto obtain the titanium dioxide pigment for the decorative laminated paper. The method provided by the invention has the advantages that the titanium dioxide pigment prepared by the method has the characteristics of high light performance, good whiteness and a high retention rate in the laminated decorative paper, and the prepared titanium dioxide pigment has a medium color bottom phase and the advantage of easy color matching, and can be widely used in the field of the high-end laminated decorative paper.

The invention discloses a production method of rutile-type titanium dioxide for decorative laminated paper, which comprises preparing titanium dioxide primary product slurry, diluting, coating a silicon-containing compound, coating an aluminum-containing compound, aging, filtering, washing with water, Drying, calcining, crushing and other steps, which first coat a layer of silicon film on the surface of titanium dioxide and then coat a layer of aluminum film, greatly improve the weather resistance of titanium dioxide, and remove the coating by calcining and heating. The hydroxyl group on the film avoids the reaction of electron pairs and meets the high light resistance requirements of titanium dioxide in the field of decorative laminated paper, so that cheap silicon compounds can be used to replace zirconium compounds, phosphates and rare earth metals to produce high light resistance decorations Titanium dioxide for laminated paper.
