One piece moulded adjustable length Security Seal for sealing Food- and Duty Free Trolleys in the Airline and Catering business. The special-shaped ribbon profile (3.0 x 2.6 mm) increases security level and avoids pseudo sealing. Due to its special design this seal hangs always in the right position so that the barcode or number is always visible. Various colours for logistical functions are available. Customer name/logo for clear identification. Bar-coding for fast, accurate and reliable data capture and streamlining operations.
