摘要：
Ultrasonically bonded laminated absorbent products comprising a liquid permeable top sheet, a liquid impermeable back sheet, an absorbent core positioned between the liquid permeable top sheet and the liquid impermeable back sheet, and an adhesive composition are disclosed. The laminated structure further comprising an embossed pattern stamped onto the liquid permeable top sheet, the liquid impermeable back sheet, the absorbent core, or any combination thereof. The adhesive composition comprises a mixture of atactic and isotactic polymers such that it has melt and flow characteristics similar to those of the topsheet and backsheet.
