Abstract
The invention proposes an embossed sheet (10) comprising at least one ply (12) of tissue having an embossing pattern comprising at least one series of protuberances (18) formed projecting from one surface of the said ply (12) of tissue, and at least one ply joined to the said at least one ply (12) of tissue and located opposite the said surface of the ply (14) of water-soluble material, characterized in that the ply (14) of water-soluble material is joined to the said at least one ply (12) of tissue at the summits (18a) of at least part of the protuberances (18). The invention also proposes a method for manufacturing such a multi-ply sheet (10).
Claims10
An embossed sheet, comprising:
- at least one ply of tissue, comprising an embossing pattern comprising a plurality of protuberances projecting from a surface of the at least one ply of tissue, the protuberances having summits;
- and
- at least one ply of water-soluble material joined to the at least one ply of tissue,
- wherein the at least one ply of water-soluble material is joined to the at least one ply of tissue via the summits of at least a portion of the protuberances,
- wherein the at least one ply of water-soluble material is joined to the at least one ply of tissue by partial dissolution of the at least one ply of water-soluble material, and
- wherein the at least one ply of water-soluble material comprises an at least 90% hydrolyzed polyvinyl alcohol.
An embossed sheet comprising:
- at least two plies of embossed tissue, wherein each ply of tissue comprises a plurality of protuberances, and wherein the plurality of protuberances comprise summits;
- and
- at least one ply of water-soluble material arranged between the two plies of tissue and joined to the summits of at least a portion of the protuberances on each ply of tissue by partial dissolution of the at least one ply of water-soluble material, wherein the at least one ply of water-soluble material comprises an at least 90% hydrolyzed polyvinyl alcohol.
