ABSTRACT:
A confidential envelope/bag is composed of a face and a back. The face and the back are linked with each other and formed with an edge at circumference; a sealing print is formed across the edges either at the back or on both the face and the back. The sealing print includes patterns, marks, graphics, texts or numbers made of paint, coating, ink, fluorescent dye, or even concaves, or extrusions. The circumference of the face and the back are adhered to each other with a suitable region to form a sealing zone.
