LEMBARAN PEMBERSIH LAPIS-GANDA

摘要

A multi-ply cleaning sheet (S) which comprises a first layer (1) with a plurality of holes (3) passing through it and a second layer (2), the first and second layers being placed on top of the other and bonded together so that the holes are open at one surface of the first layer and closed by the second layer at the other surface of the first layer. Owing to the first layer with holes, the cleaning sheet removes dirt effectively but does not permit dirt to penetrate to the reverse side because the holes are blocked by the second layer.
