Water-dispersible composite structure and method of producing the same
20230074973 · 2023-03-09 ·

A water-dispersible composite structure, which comprises one or more layers, and a method of producing the same. At least a part of the layers is formed by a fibrous web or sheet containing 50-90 parts by weight of wood fibers and 10-90 parts by weight of annual or perennial plant fibers and/or 10-50 parts by weight of synthetic short-cut fibers, and 0.1-20% by weight of a binder, calculated from the weight of the fibers, and at least a part of the binder being a water-soluble polymer and another part a water dispersible binder, and the fibrous sheet or web being produced by wet forming. By means of the invention, the fibers of the composite structure can be recovered and recycled by equipment conventionally used in the paper and paperboard industry.

A PACKAGING MATERIAL AND A POUCHED PRODUCT FOR ORAL USE
20230203757 · 2023-06-29 ·

The present invention relates to a packaging material for use in a pouched product for oral use in order to enclose a filling material. The packaging material is a saliva-permeable nonwoven material comprising fibres. The packaging material is a wetlaid nonwoven material, or, alternatively, the fibres are carded and the nonwoven material is hydroentangled, or, alternatively, the fibres are carded and the packaging material has a basis weight ≤30 g/m.sup.2. 50%-100% of the fibres are cellulose-based staple fibres, and 0%-50% of the fibres are thermoplastic fibres, with % numbers being based on total weight of fibres at 21° C. and 50% RH. The packaging material further comprising at least 10% of a binder, taken as a wt % of a total weight of the packaging material. The present invention also relates to a pouched product for oral use comprising such a packaging material. The present invention further relates to a method for manufacturing of a packaging material for a pouched product for oral use.
