1. A body waste collecting device comprising: a collecting pouch; and an adhesive wafer connected to the collecting pouch for attaching the collecting pouch to the body, said adhesive wafer including: at least one intermediate layer of adhesive; a skin facing layer of adhesive; a film layer configured to reduce a peel force of the adhesive wafer without compromising other adhesive properties thereof, the film layer being positioned between the skin facing layer of adhesive and the intermediate layer of adhesive, wherein a thickness of the film layer is below 100 gm; and a backing layer positioned adjacent to the intermediate layer of adhesive on an opposite side of the intermediate layer of adhesive from the film layer, the intermediate layer of adhesive and the skin facing layer of adhesive including liquid impermeable, moisture permeable soft adhesives and the intermediate layer of adhesive comprising NaCl particles. 2. The collecting device according to claim 1, wherein a thickness of the skin facing layer of adhesive is below 200 μm. 3. The collecting device according to claim 1, wherein the film layer is permeable, and wherein the permeability of the film layer is above 1000 g/m2/24 h. 4. The collecting device according to claim 1, wherein the film layer is perforated. 5. The collecting device according to claim 1, wherein the film layer has a higher modulus than a modulus of the intermediate layer of adhesive. 6. The collecting device according to claim 1, wherein the film layer is selected from a group consisting of ethylene vinyl acetate (EVA), ethylene butyl acetate (EBA), polyurethane (PU), or polyethylene (PE). 7. The collecting device according to claim 1, wherein the intermediate later of adhesive is absorbent. 8. The collecting device according to claim 1, wherein the skin facing layer of adhesive and the intermediate layer of adhesive have a modulus G* of less than 50,000 Pa measured at 1 hz and 32° C. 9. The collecting device according to claim 1, wherein the skin facing layer of adhesive of the liquid impermeable, moisture permeable adhesive composition includes a permeable polymer selected from the group consisting of polyalkyleneoxide, polyurethane, ethylene vinyl acetate, silicone, polyacrylate, and mixtures thereof. 10. The collecting device according to claim 1, wherein the intermediate layer of adhesive of the liquid impermeable, moisture permeable adhesive composition includes a permeable polymer selected from the group consisting of polyalkylenoxide, polyurethane, ethylene vinyl acetate, silicone, polyacrylate, and mixtures thereof. 11. The collecting device according to claim 9, wherein the permeable polymer has a moisture vapor transmission rate of higher than 100 g/m2/24 hrs. 12. The collecting device according to claim 9, wherein the permeable polymer is low-absorbent and absorbs less than 8% in weight at equilibrium. 13. The collecting device according to claim 1, wherein the water vapor permeability of at least one of the skin facing layer of adhesive and the intermediate layer of adhesive of the liquid impermeable, moisture permeable adhesive composition is higher than 100 g/m2/24 h. 14. The collecting device according to claim 1, wherein the intermediate layer of adhesive is based on a same type of polymer ingredients as a permeable adhesive composition used in the skin facing layer of adhesive. 15. The collecting device according to claim 1, wherein the intermediate layer of adhesive has a thickness that is greater than a thickness of the skin facing layer of adhesive. 16. The collecting device according to claim 1, wherein the skin facing layer of adhesive has a thickness that is less than 33% of a thickness of the intermediate layer of adhesive. 17. The collecting device according to claim 1, wherein the collecting device is an ostomy appliance. 18. The collecting device according to claim 1, wherein the collecting device is a fecal collecting device. 19. The collecting device according to claim 1, wherein the collecting device is a fistula collecting device.
