Box-sealing tape, parcel tape or packing tape is a pressure-sensitive tape used for closing or sealing corrugated fiberboard boxes. It consists of a pressure-sensitive adhesive coated onto a backing material which is usually a polypropylene or polyester film which is oriented to have strength in both the long (machine) direction and the cross direction. Most often, the tape is 48 mm (approx 2 inches) wide but it is also used in 72 mm (approx 3-inch) widths. A variety of backing strengths and calipers as well as adhesive formulations are available. It is often transparent or tan (beige, buff, brown). Other colors and printing are sometimes available. ==Uses== The tape is most often used as a closure for regular slotted containers (RSCs). A "single strip" or "center seam" closure is applied over the center seams of a box extending 50–75 mm (2–3 inches) onto the end panels. The tape can be used as a "six-strip" closure or "H-seal" by applying cross strips on the ends of the box. This is used when a relatively weak tape is used or when extra box reinforcement is needed. This method also seals the box to help keep contaminants out. This tape has also been used by artists (E.g.Mark Jenkins) as a way to create molds of objects, as the strength of the tape allows for a strong shell for the mold when completed. 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「Box-sealing tape」の詳細全文を読む スポンサード リンク
