摘要：
A liquid-dispensing pad has a perforated generally elastic film forming a front wall, a liquid-impervious plastic rear wall, a weld peripherally securing the front wall to the rear wall, and a liquid-retaining core between the front and rear walls. The perforated film is a coextruded film having an elastic inner layer turned toward the core and an inelastic outer cover layer turned away from the core. This cover layer forms an outer face of the liquid-dispensing pad and is composed of polyolefin. A thickness of the cover layer is less than 15 μm, and a thickness ratio of the elastic inner layer to the inelastic outer cover layer is at least 10:1.
