摘要:
An ID document includes a document core and a multi-layer laminate. The multi-layer laminate includes at least three layers: a top layer, a middle layer, and a bottom layer. The top layer, in combination with other layers, provides durability to the ID document. The top layer can be made of a material with strong intrusion or scratch resistance and a high thermal softening/deformation point and can also have high resistance to solvents. The middle layer may be made of a material with a low melting point, and may also have high resistance to solvents. The bottom layer helps to facilitate strong binding to the document core or inlay and may be made of a material with a relatively high melting point.
