<p>The pad (100) has a film portion (2) arranged between a film-type carrier layer (1) and an anti-static, cleaning cloth layer (3). A surface of the carrier layer facing the cloth layer is provided with a self-adhesive or adhesive element exhibiting low pressure-sensitivity adhesive characteristics, for peeling off the pad that is pressed on a solid surface. The carrier layer is adhered with the film portion to form a non-releasable film composite (20). The cloth layer is connected with the film composite by an adhesive layer (6). The carrier layer is made of open or closed-pore polymeric foam. Thickness (D2) of the film portion is greater than 0.5 mm. Thickness of the adhesive layer is greater than 20 micrometers. Thickness (D1) of the carrier layer is in a range of about 0.2 to 0.4 mm. The carrier layer and/or the film portion are made of biodegradable materials such as cellulose or starch. The cloth layer is made of knitted, interlaced, woven or non-woven textile material such as micro-fiber. The cloth layer is treated with a bactericidal agent such as metal ions. The pad is formed in a round, oval, polygonal or rectangular shape, or in form of heart, ball or tricot.</p> |
