A packaging material and a pouched product for oral use

Abstract

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 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.
