The FFA-BFS is a specialized high-speed flow wrapping machine designed for BFS (Blow-Fill-Seal) eyedrop chain bottles—capable of packaging single or multiple connected units (trays) of low-density polyethylene ampoules. It seamlessly integrates with upstream production lines via an automatic feeding system, delivering a maximum line speed of 120–130 packs per minute (with stepless speed regulation) to meet high-throughput pharmaceutical packaging demands.
