PRODUCT OVERVIEW
MC-JY350J overview
Quick answer
MC-JY350J is a single-use, pull-tight seal for closures that need a longer loop: roll cages, catering trolleys, courier sacks and container door handles. It is 350 mm (13.8 in) long with a 45 × 26 mm flag and a 3.5 mm tail, weighs 5.59 g and has a metal clip inside the polypropylene head. Feed the tail through the head and pull tight. The catalogue lists 15 kg tensile. MOQ is 1,000 pieces, packed 1,000 per carton.
How it locks
The tail passes one way through the metal clip and cannot be loosened.
Not suitable when
- removal must be by hand – see MC-410T or MC-ERPS400T;
- you need an extra-long loop – see MC-R5 (550 mm) or MC-R650;
- your buyer requires a tested container seal.
