Active additives in absorbent articles, such as sanitary napkins, panty liners, tampons, incontinence protectors and diapers have been found to lose their properties due to taking-up moisture during storage and transportation for instance, when conventional packaging materials are used. The invention relates to the use of a moisture impervious film material for packaging an absorbent article comprising one or more active moisture-sensitive additives. Packaging is effected in film material that has low vapor and gas permeability and in packaging unites that have tight joins or seams.

The method according to claim 1, wherein the highest WVTR of the package is 4 g/m2/calendar day.3. The method according to claim 1, wherein the highest WVTR of the package is 2 g/m2/calendar day.4. The method according to claim 1, wherein the highest WVTR of the package is 1 g/m2/calendar day.5. The method according to claim 1, wherein the package comprises a moisture indicator.6. The method according to claim 1, wherein the package comprises a moisture absorbent.7. The method according to claim 1, wherein the at least two layers comprise different materials.8. The method according to claim 5, wherein the moisture indicator is a silica gel.9. The method according to claim 1, wherein the moisture sensitive additive is an active additive.10. A pack enclosing an absorbent article for absorption of bodily fluids, the absorbent article selected from the group consisting of a sanitary napkin, a panty liner, a tampon, an incontinence protector, and a diaper, wherein the absorbent article has at least one moisture-sensitive additive, the pack comprising at least one essentially impervious film material with impervious joins or seams, the impervious film material being selected from the group consisting of PE (polyethylene), PP (polypropylene), PET (polyester), PA (polyamide), PETP, PVA (Polyvinyl alcohol), aluminum foil, aluminum oxide, and silicon oxide and wherein the highest WVTR (Water Vapour Transmission Rate) of the pack is 6 g/m2/calendar day in accordance with ASTME 398-83 in effect as of Jun. 9, 2000, wherein the sack comprises at least two material layers, of which one is an inner moisture barrier layer that is comprised of the at least one essentially impervious film.11. The pack according to claim 10, wherein the highest WVTR of the pack is 4 g/m2/calendar day.12. The pack according to claim 10, wherein the highest WVTR of the pack is 2 g/m2/calendar day.13. The pack according to claim 10, wherein the highest WVTR of the pack is 1 g/m2/calendar day.14. The pack according to claim 10, wherein the package is fully sealed with the impervious joins or seams.15. The pack according to claim 10, wherein the moisture sensitive additive is an active additive.
