Postcard and its manufacturing method

摘要

A postcard includes a postcard material and a label covering at least part of the postcard material, and the label in turn, includes a top material at least partly opaque, an inter-layer peel ply formed on the principal surface of the top material, and an adhesive layer formed on the principal surface of the inter-layer peel ply. With this postcard the top material of the label can be easily peeled off the postcard material in the part where the inter-layer peel ply is formed. Secret information shown on the principal surface of the postcard material is visible when the top material is peeled off the postcard material.
