PRODUCT OVERVIEW
MC-250big flag overview
Quick answer
MC-250 big flag is a single-use, pull-tight seal with a 105 × 85 mm (4.1 × 3.3 in) flag – large enough to print a full logo and address or to stick a shipping label or barcode sticker. It is 250 mm long overall with a 2.6 mm tail and a metal locking clip in the polypropylene head; it weighs about 7 g. Feed the tail through the head and pull tight. The catalogue lists an average tensile strength of 85.26 N. MOQ is 1,000 pieces, packed 200 per bag and 2,500 per carton.
How it locks
The tail passes one way through the metal clip; the loop tightens but cannot be loosened.
Not suitable when
- you need a long loop – the flag takes up 105 mm of the 250 mm length; see MC-R6 (462 mm, 105 × 56.5 mm flag);
- a small flag is enough – see MC-260 big flag (60 × 30.3 mm);
- the closure needs more than about 8 kg of holding force.
Compared with similar models
- MC-R6 – 462 mm pull-tight seal with a 105 × 56.5 mm label holder and more than 20 locking points.
- MC-260 big flag – 260 mm seal with a 60 × 30.3 mm flag.
