Polymeric foamed compositions, foam padded materials that include such polymeric foamed compositions, and packaging articles (e.g., envelopes) that include such foam padded materials, wherein the foamed composition includes: a polymeric component including a copolymer including divalent hydroxyethylene monomer units and divalent dihydroxybutylene monomer units; wherein the composition is in the form of an at least partially water-soluble foam.

A biodegradable and compostable sheet of material for picking up and disposing of dog excrement in an environmentally friendly manner. The sheet comprises paper or paperboard that is made grease resistant. The sheets may be stored in individual sheets or on an elongated sheet that may be folded and rolled for use with dispensing units. In operation, a user grabs or tears off an individual sheet and then places the sheet over the dog excrement so that it is located generally about the sheet's center. The corners or top edges of the sheet may then be grasped and rotated in a direction opposite of the rotation of the central section so that a twist end is formed to retain the dog excrement within a sack. The sack may then be disposed of in a trash can or composter, wherein it will degrade in an environmental safe way.

The invention relates to a multi-layer cardboard material (10), comprising at least one first fibrous-material layer (12), which has a cellulose-containing base material, and at least one second fibrous-material layer (14) comprising a mixture of cellulose-containing material and fine material particles, wherein a material of origin for the fine material particles is coco peat and the fine material particles have a particle size <0.5 mm, in particular <0.3 mm. The invention further relates to a method for producing a multi-layer cardboard material (10), in particular a multi-layer cardboard web, comprising at least one first and one second fibrous-material layer (12, 14), and the use of a fibrous-material layer comprising a mixture of cellulose-containing material and fine material particles.

The present invention relates to a crumple-resistant security sheet comprising fibers; an anionic polymer in a proportion lying in the range 5% to 45% by dry weight relative to the total dry weight of the fibers, and presenting a glass transition temperature greater than 40 C.; and a main cationic flocculation agent in a quantity lying in the range 1% to 5% by dry weight relative to the total dry weight of the fibers.

A hydrolysable sheet obtained by impregnating a base paper sheet, to which a water-soluble binder is added, with a chemical solution, wherein the base paper sheet is obtained by applying a ply process to a plurality of sheets of base paper and has a basis weight of from 30 gsm to 150 gsm, wherein a compounding ratio of softwood pulp to hardwood pulp is less than 1/1, wherein the chemical solution contains a cross-linking agent, which causes the water-soluble binder to initiate a cross-linking reaction, and a trihydric or higher alcohol, and wherein, with respect to a weight of the base paper sheet, the base paper sheet is impregnated with the trihydric or higher alcohol at 1% to 20% by weight.

A recording medium is provided, such as paper, secured by magnetic microwires. The recording medium comprises: a pulp structure formed by pulp fibers, said pulp structure carrying microwires having a metal core of a predetermined material composition, and an insulating layer coating on said metal core; and at least one coating layer on at least one side of said pulp structure. The pulp structure is a single-layer structure with the microwires fully embedded in said single layer, the microwires having cross-sectional dimensions approximately equal to cross-sectional dimensions of the pulp fibers.

A paper packaging material, and method for manufacturing it, having a paper layer with a polyethylene coating on one surface, a biodegradable resin grid on the opposite surface to enhance its strength while maintaining reduced weight and a thermo-sealing resin, which eliminates the use of glues in the packaging process. The vegetal resin is made out of vegetable wax, acrylic styrene copolymer, demineralized water, water based silicone and natural fungicide. The method includes the steps of printing graphics on one side of the web, drying the paper, applying a vegetal resin on the other side and a film of polyethylene on the top of the printed side. Thermo-sealing varnish is applied in predetermined areas.

An article in the form of a printable substrate having a showthrough value of about 0.14 or less, and an opacity value of at least about 88% which includes a paper substrate with a first and second surfaces formed of paper fibers having a basis weight of from about 12 to about 32 lbs/1300 ft.sup.2, and a substrate filler in an amount in the range of from 0 to about 30% by weight of the paper substrate; and a surface size layer on at least one of the first and second surfaces, the surface size layer having about 50 lbs or less per ton of the paper substrate of a starch surface sizing agent and a multivalent metal salt drying agent in an amount sufficient to impart to the at least one of the first and second surfaces a black print density value of at least about 0.8 when inkjet printed with pigmented inks and a waterfastness value of at least about 85% when inkjet printed with dye-based inks, the printable substrate having a MD tensile strength of at least about 12 lbs/in. and a CD tensile strength of at least about 6 lbs/in. Also, a method for preparing such a printable substrate.
