According to the present invention, the back sheet may be in the form of a thin layer, a non-woven fabric or a thin / non-woven fabric. First, a thin layer form of the back sheet will be described. Many manufacturing techniques can be used to make a backsheet in the form of a thin layer in accordance with the present invention, such as, for example, casting or stretch molding. For the lifespan, the back sheet is preferably made by blending the fragrance with the thermoplastic polymer constituting a thin back matrix, to prepare the masterbatch (hereinafter, a masterbatch odor), and the masterbatch is included. The odor is mixed with a traditionally adjusted masterbatch, and the mixture is made through a T-die at 170 to 240C, preferably at i800c to 230. (3, as described in detail below. Mix the masterbatch fragrance and the adjusted masterbatch in the expected proportions. Then the mixture AUCE: \ D \ patent \ PA-011-0001 6 200528074 is fed-in overturned. After the extrusion and mixing of the extruder, the mixture can be completely dispersed. The impurities are removed from the mixture by a combination of filters. Then it is cast into a thin layer through the small τ mold. The thin layer after casting passes through a cooling drum, wherein the temperature of the chilled cooling drum is preferably maintained between 10 ° C and 30 ° C, and preferably between irc and 25t, which is lower than the temperature of the dedicated roller (20 ° C to 35 ° C, preferably 25. (: to 3 (TC), in order to maintain the fragrance. Cut the thin layer into strips and wind to the desired size. A corona-treated text embossed or The printing step can be further included in the process as expected. The backsheet thus configured can be used in Erming. It is used in the present invention to contain 30% to 50% of the thermoplastic polymer of masterbatch fragrance, 20% aroma and 40% to 60% additives. Used in the masterbatch of the present invention 40% to 60% of thermoplastic polymer and 40% to 60% of additives. According to the expected characteristics, the additives contained in the flavor of the masterbatch and the masterbatch are adjusted to an antioxidant, filler particles, dyes , And the like. The thermoplastic polymers representing the masterbatch fragrance and the masterbatch can be different or identical to each other. Examples of such thermoplastic polymers include, but are not limited to, very low density polyethylene, low density Polyethylene, high-density polyethylene, copolymers of polyethylene and ethylene and Q_Ci2a — olefins, propylene and copolymers with ethylene and / or Q_Ci2 α-olefins and flexible polyolefins include polymers mainly composed of propylene, There are both random and parallel propylene groups on the main polypropylene chain. Elastomers-for example, polyurethanes, copolyetheresters, polyamine block copolymers with ethyleneamines, ethylene ethyl acetate copolymers, A fluorene copolymer having this general formula A-B-A, or A-B, such as copolymer (styrene / ethylene-butene), acetophenone-poly (ethylene-propylene) _styrene, styrene- Poly (ethylene) butene Styrene, polystyrene / poly (ethylene-butene) / polystyrene, poly (styrene / ethylene-butene / styrene), and the like.
