Carton staplers are used to apply carton staples to boxes and packaging, securing the sides, base, and top for transport. Battery-operated carton staplers cause less strain than manual-operated staplers. Manual and pneumatic foot-operated staplers are for high-volume applications. Pneumatic hand, stick, and roll staplers use button-operated air pressure to seal staples. Plier staplers are handheld carton staplers with a bottom handle that is used to staple the sides of corrugated boxes. Manual and pneumatic plier staplers are available, as well as wide crown plier staplers for furniture stapling.
