摘要

The security document card has a carrier (10) with a cladding (5) on at least one side. The carrier contains high density polyethylene (HDPE) and linear low density polyethylene (LLD-PE), and the coating is of polycarbonate. The carrier material is augmented by a bulking material using TiO2 and/or CaCO3, at a rate of at least 5 wt.% or at least 20 wt.%. The thickness of the carrier is at least 100 mum with a thinner cladding, or the carrier is at least 120 mum thick with a cladding thickness of at least 100 mum. The cladding is bonded to the carrier by a fusible adhesive activated at a temperature at least100degreesC and at most200degreesC. The security data are written on to the card by a laser before and/or after the cladding is bonded to the carrier.
