Abstract

A high-opacity cellulose-free synthetic paper (58) is formed from a wet-laid nonwoven web of thermoplastic fibers (44), all or most of which fibers are made of a predetermined polymeric material. The wet-laid web is dried to remove excess water (46), drying (48) being carried out at temperatures below the melting temperature of the predetermined polymeric material. The dried nonwoven web is saturated on at least one side with a pigmented binder (50) forming a continuous coating thereon. The binder is cured at temperatures below the melting temperature (54) of the predetermined polymeric material.
