Composite plastic sheet and process for making the same

摘要

A composite sheet comprises a hydrophobic first plastic film layer 2 forming an upper surface of the sheet, a second plastic film layer 5 forming a lower surface of the sheet and a hydrophobic intermediate fibrous assembly layer 3 disposed between these two layers 2, 5. The first plastic film layer 2 includes a plurality of first plane regions 8 spaced one from another and extending parallel one to another in one direction and sawtooth-shaped first rising regions 12 formed along edges of the first plane regions 8 and the second plastic film layer 5 includes a plurality of second plane regions 58. Such composite sheet is breathable but liquid-resistant and suitable for use for disposable garments.
