1. A flexible packaging for disposable absorbent articles composed of a polyethylene film which can be opened and closed semi-tightly, comprising a front face (12),a rear face (14),a top bellows (16),a top part (26),a bottom part (28), andan opening system (20), whereinthe top part (26) has a distal end located above the top bellows (16);the front face (12) has a width and first longitudinal edges, the rear face (14) has a width and second longitudinal edges, and wherein the first longitudinal edges are sealed to the second longitudinal edges by a first side seal and a second side seal (42);the flexible packaging (10) in both an open and closed state has in the distal end of the top part (26) an inverted U-shape member, which is an extension of the front face (12) and is located above the top bellows (16), comprising an upward layer and a downward layer, such that the upward layer extends upwards continuous with the front face (12), above the top bellows (16) of the flexible packaging (10) and subsequently turns downwardly onto itself, thereby forming the downward layer, wherein the downward layer reaches the top bellows (16) of the flexible packaging (10) adjacent to the front face (12) of the flexible packaging (10) and is folded in a V-shape, thereby forming the top bellows (16) of the flexible packaging (10);and wherein the opening system (20) is located within the inverted U-shape member. 2. The flexible packaging for disposable absorbent articles as claimed in claim 1, wherein the opening system (20) comprises a closing system (22) and an easy-opening system; such that the easy-opening system is located upwards of the closing system (22), and wherein the closing system (22) has a peel-strength. 3. The flexible packaging for disposable absorbent articles as claimed in claim 2, wherein the closing system (22) comprises a first element and a second element; the first element is bonded to the upward layer and the second element is bonded to the downward layer;the first element faces the second element and the second element faces the first element, such that the first element and the second element together are capable of closing the flexible packaging semi-tightly. 4. The flexible packaging for disposable absorbent articles as claimed in claim 3, wherein the closing system (22) is a hook and loop type system. 5. The flexible packaging for disposable absorbent articles as claimed in claim 3, wherein the closing system (22) is an airtight-seal type system (zip lock). 6. The flexible packaging for disposable absorbent articles as claimed in claim 2, wherein the easy-opening system comprises a weakening line (24) and a removable strip (30), such that the weakening line (24) comprises all the width of the front face of the flexible packaging; the removable strip (30) is placed above the weakening line (24); andthe easy-opening system, the closing system, the weakening line and the removable ship are located in both the upward layer and the downward layer of the inverted U-shape. 7. The flexible packaging for disposable absorbent articles as claimed in claim 2, wherein the peel-strength of the closing system (22), measured at 180°, is at least 150 g/cm. 8. The flexible packaging for disposable absorbent articles as claimed in claim 1, wherein the flexible packaging (10) further comprises a handle (46) comprising a strip of the same polyethylene film from which the packaging is composed, wherein the handle (46) is adjacently attached to a first top part of the first side seal and a second top part of the second side seal (42), such that the handle (46) has a maximum width equal to a width of the top bellows of the flexible packaging when the flexible packaging is filled with disposable absorbent articles, and a minimum length equal to the width of the front face (12) or the width of the rear face (14).
