Abstract

The present disclosure relates to a method for producing an oral pouched snuff product comprising a filling material (29, 10) and a saliva-permeable pouch (43) enclosing the filling material (29, 10), the product (29, 10) having a moisture content of at most 20% by weight, in particular at most 10% by weight, based on total weight of the product (29, 10), the saliva-permeable pouch (43) having one or more seals (45, 46), and said filling material (29, 10) comprising at least 20% by weight, based on dry weight of the filling material (29, 10), of at least one ingredient having a melting temperature below 180° C., the method comprising ultrasonically welding and cutting an advancing web (32) of packaging material (7) to which the filling material (29, 10) has been supplied. The present disclosure also provides an oral pouched snuff product which is obtainable by this method.

Dependent claims

A method for producing an oral pouched snuff product comprising a filling material and a saliva-permeable pouch enclosing the filling material, said oral pouched snuff product having a moisture content of at most 20% by weight based on total weight of the product, said saliva-permeable pouch having one or more seals, and said filling material comprising at least 20% by weight, based on dry weight of the filling material, of at least one ingredient having a melting temperature within the range of from 70° C. to 155° C., the method comprising:

supplying and advancing at least one web of packaging material, said at least one web of packaging material advancing in a direction of travel;
supplying the filling material to said at least one advancing web of packaging material;
and
welding and cutting said at least one advancing web of packaging material to which the filling material has been supplied to provide a plurality of pouches enclosing the filling material, wherein said welding of said at least one advancing web of packaging material to which the filling material has been supplied is provided by ultrasonic welding.

1 more element

An oral pouched snuff product comprising a filling material and a saliva-permeable pouch of a packaging material enclosing the filling material, said oral pouched snuff product having a moisture content of at most 20% by weight based on total weight of the product, said saliva-permeable pouch comprising at least one elongated seal sealing the packaging material and having a seal length extending along a first direction, and said filling material comprising at least 20% by weight, based on dry weight of the filling material, of at least one ingredient having a melting temperature within the range of from 70° C. to 155° C., wherein:

said at least one elongated seal has a seal width extending along a second direction transverse to said first direction, said seal width being within the range of from 0.1 mm to 2 mm, and
said at least one elongated seal being an ultrasonically provided weld formed by simultaneous ultrasonic welding and cutting of the packaging material such that a cut is provided in a welded area, thereby at least one outermost end portion of the pouch being sealed by the at least one elongated seal.
