PRODUCT OVERVIEW
MC-R6 overview
Quick answer
MC-R6 is a single-use, pull-tight seal whose large flag doubles as a label holder: at 105 × 56.5 mm (4.1 × 2.2 in) it takes a printed logo, a stuck-on label or handwriting with a marker pen. It is 462 mm (18.2 in) long, with more than 20 locking points along a 213 mm toothed section, so the loop can be set at many sizes. Feed the tail through the head and pull tight. The catalogue lists approx. 20 kgf tensile. MOQ is 1,000 pieces, packed 100 per bag and 1,000 per carton.
How it locks
The toothed strap passes one way through the head; each tooth is a locking point, and the loop cannot be loosened.
Not suitable when
- a small flag is enough – shorter seals such as MC-JY350J cost less;
- removal must be by hand – see MC-ERPS400T.
Compared with similar models
- MC-250 big flag – 250 mm seal with a 105 × 85 mm flag.
- MC-TB01 – snap-in seal for crates with sealing holes.
