Box staplers HB-PN are designed for pneumatic closing of filled boxes. Wide staples seal securely and neatly. This method of closing cartons saves labour and material costs. The box staplers are delivered in two modifications, one for 15 mm staple leg length and one for 18 mm. The both types has adjustable stapling head for different thickness of cartons. A stapled box is stronger than a conventionally taped one. The staples join outer as well as inner part of package, but tapes join only outside parts. The locking of the flaps makes the carton more rigid and gives is better stacking strength. The staples are metal coated and are 100% recyclable!
