PRODUCT OVERVIEW
MC-RTPS is a single-use, round-tail pull-tight seal made in four lengths, so one design covers most bag, cart and door closures: Each has a metal clip in a virgin polypropylene head. Feed the round tail through the head and pull tight. MOQ is 1,000 pieces; packing depends on length.
The round tail passes one way through the metal clip and cannot be loosened.
