Abstract:
Aqueous suspensions of starch, particularly for use in the paper and board industry, are stabilised by addition of a minor amount of a hydrophilic polymeric viscosity-increasing agent such as xanthan gum. The suspensions may also comprise a major amount of an anionic polysaccharide or polyacrylate. Viscous treating agents of this type can be applied to paper or board during manufacture, by using a spinning surface atomiser, especially a spinning cone atomiser.
Abstract:
The present invention relates to a paper or non-woven web, comprising fibers and at least one crosslinking or functionalization agent selected from the group consisting of carboxylic acids, halogenated heteroaromatic compounds and salts thereof, wherein said at least one crosslinking or functionalization agent has a molecular weight of not more than 1000 g/mol, and wherein at least a part of said crosslinking or functionalization agent is bound to said fibers, a process for producing said paper or non-woven web, and the use of said crosslinking or functionalization agent in a paper or non-woven web.
Abstract:
The present invention is directed to a process comprising: (i) extracting ≥50% by weight of all carrageenan from a carrageenan-containing seaweed material to obtain a cellulose-containing seaweed residue; and (ii) purifying the cellulose-containing seaweed residue by at least one of hydrolysis or bleaching. The present invention is also directed to the cellulose obtained from the process, as well as products containing the cellulose-containing seaweed material.
Abstract:
A food packaging material comprises a paper, paperboard or cardboard substrate and a barrier coating on the substrate, wherein the barrier coating comprises the combination of starch, seaweed extract and paper fibers.
Abstract:
Gezeigt wird ein Filterhüllpapier für einen Rauchartikel, das einen Anteil an Langfaserzellstoff von mindestens 30 Gew.-%, vorzugsweise mindestens 40 Gew.-% bezogen auf die reine Fasermasse des Papiers hat. Der Mahlgrad des Langfaserzellstoffs nach ISO 5267, Schopper-Riegler-Verfahren beträgt zwischen 80 °SR und 100 °SR, vorzugsweise zwischen 85 °SR und 95 °SR. Das Filterhüllpapier hat einen Füllstoffgehalt von weniger als 10 Gew.-%, vorzugsweise weniger als 8 Gew.-% und besonders vorzugsweise weniger als 6 Gew.-% bezogen auf die Gesamtmasse des Papiers und ist mit einem Material imprägniert, das geeignet ist, eine wässrige Zusammensetzung, insbesondere eine wässrige Lösung oder Suspension zu bilden. Die Olbeständigkeit des Filterhüllpapiers weist einen KIT-Level nach Tappi T559 cm-02 von mindestens 4, vorzugsweise von mindestens 5 auf.
Abstract:
The present invention is directed to a fibre-reinforced film comprising a paper- reinforced alginate film containing polyhydric alcohol. Further, the invention is directed to a process for producing the fibre-reinforced film, and the use thereof for packaging food products, particularly meat products to be cooked and smoked.
Abstract:
The present invention relates to a containerboard packaging material comprising at least one non-wood alternative pulp material wherein said non-wood alternative pulp material is present in an amount of from about 5% to about 100% and wherein said material replaces at least a portion of conventional fiber materials.
Abstract:
This invention relates to a paper substrate containing high surface sizing and low internal sizing and having high dimensional stability, as well as methods of making and using the composition.
Abstract:
Aqueous compositions having advantageous rheological properties, preferably including any of enhanced yield stress, enhanced viscosity, and/or enhanced water retention, are disclosed. Included are low-viscosity compositions having high yield stress. The present invention also relates to processes for preparing and using the compositions. Compositions of the present invention comprise aqueous compositions of a polymer having a net ionic charge, and a viscosity promoter having an opposite net ionic charge. Compositions may also comprise a moderating agent to prevent precipitation and/or gelation.
Abstract:
The invention provides protein adhesives, and methods of making and using such adhesives. The protein adhesives contain a protein-bonding agent and plant protein composition, such as an isolated water-soluble protein fraction or ground plant meal obtained from plant biomass. The protein-bonding agent can be an anhydride compound, carboxylic acid compound, carboxylate salt compound, or combinations thereof. The protein adhesives are useful in bonding together lignocellulosic materials and other types of materials.
