The method of preparing the sanitary pad (10) with an upper layer protector (40) consisting of the following steps: i) a hygienic pad (10) with an upper layer (30), a lower layer and an absorbent inner part between them is obtained. ii) A polyethylene polymeric film is obtained as the top layer protector (40) and placed on the top layer (30). iii) the said top layer protector (40) is applied to the top layer (30) using a roller at temperatures between 75 and 85 0C and with a pressure between 3 and 6 bars. iv) In order to obtain the absorbent product with said top layer protector, said top layer protector and the sanitary pad (10) is cut to suit its final shape and size. Within the scope of the present invention; There is a sanitary pad (10) with a top layer protector (40), and the scope of said sanitary pad (10) includes a sanitary pad, daily pad and an absorbent pad. The present invention is illustrated by the following - but not limiting - embodiments; In an application within the scope of the present invention consisting of a winged sanitary pad (10), the top layer protector (40) is attached to the top layer (40) corresponding to the front (11) and back (13) regions of the sanitary pad. Thermosealing process is not applied to the edges where the wings (20) are located. The non-attached area prevents shrinkage that may occur when the wings (20) are folded while the sanitary pad (10) is packaged. When there is no pressure due to attachment, the folding process of the wings is carried out more easily. 2905.14 In another embodiment within the scope of the present invention, the sanitary pad (10) is in the form of a daily pad. The top sheet protector 40 is attached over the entire circumference of the top sheet of the diaper. Applying the attachment process to the entire perimeter of the pad ensures complete hygiene in the product. These products are not folded and packaged as a whole. In another embodiment within the scope of the present invention, the daily pad is in individually packaged form, and within the scope of the packaging in question, there are two fold marks (15) and a packaging paper attached to the liquid-proof substrate. The top layer protector (40) is attached around the sanitary napkin (10), excluding the parts where fold marks (15) are present. By not applying the attachment process to the areas where there are fold marks (15), the folding process of the sanitary napkin (10) is supported and shrinkage that may occur in these areas is prevented. In another embodiment within the scope of the present invention, the heat bonding process applied to the top layer (30) and the top layer protector (40) is not continuous. The attachment process is applied intermittently. With the intermittent attachment process, shrinkage problems that may occur during any folding and packaging model desired for the sanitary pad are prevented. In another embodiment within the scope of the present invention, the heat bonding process applied to the top layer (30) and the top layer protector (40) is in a patterned form. While such a pattern may contain attached and unattached regions, the pattern may be applied repeatedly. The top layer protectors (40) made of polyethylene film with a weight of 16 g/m2 and a width of 95 mm and 1.10 mm are rolled with a roller at 3.5 bar pressure and 80 °C, and the width of their areas is 5 mm. Peeling force measurements 2905.14 The prepared hygienic pads with top layer protector (40) are cut at a distance of 2.5 cm from the front and back edges. Cut pieces; In the peel force measuring device produced by ZWick Company, the upper layer protector (40) is placed on the upper part of the device, and the upper layer (30) is placed on the fixed lower part of the measuring device. The upper part of the machine and the upper layer protector (40) are pulled from the upper layer. The top layer protector (40) and the top layer (30) are separated from each other by the peeling force measured by the device. The peeling forces measured for the prepared sanitary pad samples are given in Table 1.
