Method for manufacturing plastic laminate sheet for security and value document e.g. passport, involves laminating stack to form composite so that core layer and outer layer are interconnected to form laminate sheet

摘要

The method involves providing plastic core layer (100). The microperforations (10,10',10",10"') are generated in perforation region (20) corresponding to joint region of core layer. The microperforations in the core layer with plastic outer layer are collated, to form a stack. The outer layer is provided to cover perforation region of core layer. The stack is laminated to form composite, so that core layer and outer layer are interconnected to form laminate sheet.
