PRODUCT OVERVIEW
MC-170B overview
Quick answer
MC-170B is a short, single-use, all-plastic pull-tight seal with a beaded tail. It is 170 mm (6.7 in) long; the catalogue gives a 30 × 19.43 mm tag, and the drawing shows 40 mm including the round lock head and a 130 mm strap with a 1.4 mm beaded section. Feed the tail through the head and pull it snug. It is 100% virgin polypropylene with no metal. Catalogue average tensile is above 3 kg. MOQ is 1,000 pieces.
How it locks
The beads pass one way through the plastic lock; the loop tightens but cannot be loosened.
Not suitable when
- the closure needs a firmer metal-clip lock – see MC-JY165 or MC-KTPS;
- the loop must be longer than about 120 mm – see MC-250B;
- removal must be by hand – see MC-210T.
Compared with similar models
- MC-250B – 250 mm beaded all-plastic pull-tight seal.
- MC-170A – 170 mm fixed-length insert-lock seal.
