Abstract: A card forming sheet includes an opaque printing sheet and a transparent film placed over the printing sheet, so that the transparent film can be peeled away from the printing sheet and cannot be re-bonded to the printing sheet. Moreover, the card forming sheet includes a transparent adhesive and a peeling sheet placed over the adhesive layer. The printing sheet is divided into a substantially rectangular address describing part, an information describing part adjacent to one side of the address describing part, and a concealing part adjacent to another side of the address describing part. The card forming sheet is folded along a boundary between the address describing part and the information describing part. The two sides are bonded together so that the printing sheet is placed to the outside, and the card forming sheet is then folded along a boundary between the concealing part and the address describing part and bonded together, removably concealing the information.

Abstract: A unit label on a first tier is connected to a unit label on a second tier by a connecting portion in a vicinity of the lower right corner portion of the first tier unit label. The strength of the connecting portion is set so that the connecting portion is separated when a corner portion of the second tier unit label is in a raised state following the first tier unit label being peeled from a release sheet. Thereby, a start portion from which subsequent unit labels can be peeled off from the release sheet can be easily made. As a result, the subsequent unit labels are easily removed from a release sheet.

Abstract: A card forming sheet according to the invention includes: an opaque printing sheet; a transparent film placed over the printing sheet so that the transparent film can be peeled away from the printing sheet and cannot be re-bonded to the printing sheet; a transparent adhesive; and a peeling sheet placed over the adhesive layer. The printing sheet is divided into a substantially rectangular address describing part, information describing part adjacent to one side of the address describing part, and concealing part adjacent to another side of the address describing part. The card forming sheet is folded along a boundary between the address describing part and the information describing part. The two sides are bonded together so that the printing sheet is placed to the outside. The card forming sheet is then folded along a boundary between the concealing part and the address describing part and bonded together, removably concealing the information.

Abstract: A personal information protecting sheet includes a base sheet and an information carrying sheet carrying a piece of personal information bonded to the base sheet so as to be separable from the base sheet. The information carrying sheet includes an information carrying portion on which the personal information is to be carried. The information carrying portion includes a separable portion partitioned by a closed-loop cut line so that the separable portion can be separated from the base sheet.
