Abstract
An absorbent article comprising a liquid permeable cover layer, an impervious barrier layer and an absorbent core between the cover layer and the barrier layer, wherein the barrier layer is impervious and biodegradable and comprises a kraft paper layer and a continuous resin coating; wherein the continuous resin coating is on the surface of the barrier layer disposed toward the absorbent core, and the continuous resin coating weight is from 10 to 18 g/m2, and the continuous resin coating is an acrylic copolymer.
Claims15
Absorbent article comprising a liquid permeable cover layer, an impervious barrier layer and an absorbent core between the cover layer and the barrier layer, wherein the barrier layer is impervious and biodegradable and comprises a kraft paper layer and a continuous resin coating,
- wherein the continuous resin coating is on the surface of the barrier layer disposed toward the absorbent core, and
- the continuous resin coating weight is from 10 to 18 g/m2, preferably 12 to 15 g/m2, and the continuous resin coating is an acrylic copolymer.
Liquid impervious barrier layer comprising a kraft paper layer and a continuous resin coating;
- wherein the continuous resin coating weight is from 10 to 18 g/m2, preferably 12 to 15 g/m2, and the continuous resin coating is an acrylic copolymer, wherein the thickness of the barrier layer ranges from 40 μm to 80 μm.
Process for the construction of an absorbent article comprising the following steps:
- Applying a continuous resin coating on a kraft paper layer, to obtain a resin coated kraft paper,
- Drying the resin coated kraft paper in an oven to obtain a barrier layer,
- Assembling the barrier layer with at least a liquid permeable cover layer and optionally an absorbent core between the barrier layer and the cover layer to obtain an absorbent article,
- wherein the continuous resin coating weight is from 10 to 18 g/m2, preferably 12 to 15 g/m2, and the continuous resin coating is an acrylic copolymer.
Use of a liquid impervious barrier layer comprising a kraft paper layer and a continuous resin coating, for the construction of an absorbent article such as a feminine hygiene product, for example a napkin, a panty liner;
- wherein the continuous resin coating weight is from 10 to 18 g/m2, preferably 12 to 15 g/m2, and the continuous resin coating is an acrylic copolymer, wherein the thickness of the barrier layer ranges from about 40 μm to about 80 μm.
