PRODUCT OVERVIEW
MC-170A overview
Quick answer
MC-170A is a single-use, fixed-length plastic tag seal: push the strap tip into the socket on the flag and it locks at one loop size. It is 170 mm (6.7 in) long – a 22 × 45 mm upright flag with a 15 mm socket and a 145 mm strap 2 mm thick – weighs 1.8 g and is made of 100% virgin polypropylene with no metal parts. The flag carries the logo and serial number. Stock colors are red, white, yellow, light blue, black and green. Catalogue average tensile is 3–5 kg. MOQ is 1,000 pieces, packed 200 per bag and 5,000 per carton.
How it locks
The strap tip is inserted into the socket and held by internal barbs; the loop cannot be resized or reopened without breaking the seal.
Not suitable when
- you need to pull the loop tight – choose a pull-tight seal such as MC-170B;
- the closure needs more than about 5 kg of holding force;
- the loop must be larger than the fixed 170 mm strap allows.
