Abstract

The invention pertains to wrapper ( 22 ) for a tampon ( 10 ), said wrapper comprising a layer consisting essentially of cellulosic fibers ( 33 ), a layer of sealing agent ( 34 ) arranged onto the layer of cellulosic fibers ( 33 ) wherein the layer consisting essentially of cellulosic fibers ( 33 ) comprises a basis weight comprised between 15 gsm and 90 gsm. The invention also relates to an assembly comprising a tampon ( 10 ) and such wrapper ( 22 ).

Claims (15)

1 . Wrapper ( 22 ) for a tampon ( 10 ), said wrapper comprising a layer consisting essentially of cellulosic fibers ( 33 ) and a layer of sealing agent ( 34 ), wherein the layer consisting essentially of cellulosic fibers ( 33 ) comprises a basis weight comprised between 15 gsm and 90 gsm.

2 . Wrapper ( 22 ) according to claim 1 , wherein the layer consisting essentially of cellulosic fibers ( 33 ) consists essentially of paper material.

3 . Wrapper ( 22 ) according to any of the preceding claims , wherein the wrapper ( 22 ) further comprises a layer of hydrophobic material ( 30 ).

4 . Wrapper ( 22 ) according to claim 3 , wherein the layer of hydrophobic material ( 30 ) comprises a peelable layer that can be separated from the layer consisting essentially of cellulosic fibers ( 33 ).

5 . Wrapper ( 22 ) according to any of the preceding claims , wherein the layer consisting essentially of cellulosic fibers ( 33 ) comprises a thickness comprised between 30 μm to 200 μm.

6 . Wrapper ( 22 ) according to any of the preceding claims , wherein the layer consisting essentially of cellulosic fibers ( 33 ) comprises cellulosic fibers with an average fiber diameter comprised between 0.5 and 50 μm.

7 . Wrapper ( 22 ) according to any of the preceding claims , wherein the layer consisting essentially of cellulosic fibers ( 33 ) comprises a first sub-layer of cellulosic fibers ( 33 a ) and a second layer of cellulosic fibers ( 33 b ), the cellulosic fibers in the second sub-layer ( 33 b ) having a greater basis weight than the first sub-layer ( 33 a ).

8 . Wrapper ( 22 ) according to any of the preceding claims , wherein the layer of sealing agent ( 34 ) has a basis weight comprised between 0.5 gsm and gsm, preferably between 1 gsm and 10 gsm, more preferably between 2 gsm and 5 gsm.

9 . Wrapper ( 22 ) according to any of the preceding claims , wherein the sealing agent is selected from water-based blister varnish, polylactic (PLA), 3-hydroxy butyric acid and 3-hydroxy pentanoic acid (3-hydroxy valeric acid) (PHBV), polyvinyl alcohol (PVOH), biobased ethylene vinyl acetate (EVA), polyurethane (PU), vinyl acetate polymers (PVA) polyethylene oxide (PEO), polyhydroxylakanoate (PHA), polycaprolactone (PCL), low-density polyethylene (LDPE), a bio coating, a printed lacquer, 1,4 succinic acid, fumaric acid, malic acid, 2,5 furan dicarboxylic acid, 3 hydroxy propionic acid, aspartic acid, glucaric acid, glutamic acid, itaconic acid, levulinic acid, 3-hydroxybutyrolactone, glycerol, sorbitol, xylitol/arabinitol or tricarboxylic acid.

10 . Wrapper ( 22 ) according to any of the preceding claims , wherein the wrapper ( 22 ) comprises a rectangular configuration, the layer of sealing agent ( 34 ) being arranged on the periphery of the wrapper ( 22 ) along at least two contiguous edges ( 38 , 40 , 42 , 46 ).

11 . Wrapper ( 22 ) according to any of the preceding claims , wherein the layer consisting essentially of cellulosic fibers ( 33 ) comprises regenerated cellulosic fibers selected from viscose, acetate and/or rayon.

12 . Wrapper according to any of the preceding claims , wherein said wrapper comprises a grasping element ( 31 ).

13 . Wrapper ( 22 ) according to claim 10 , wherein the wrapper ( 22 ) comprises uncoated portions ( 52 ) arranged between an edge ( 42 , 46 ) of the wrapper ( 22 ) and a portion of the wrapper ( 22 ) coated by a layer of sealing agent ( 34 ).

14 . Wrapper ( 22 ) according to any of the preceding claims , wherein said wrapper ( 22 ) comprises at least one graphic element ( 26 ).

15 . Assembly comprising a wrapper ( 22 ) according to any of the claims 1 to 14 and a tampon pledget ( 10 ).
