Method an apparatus and a system in which reclosable bags and components thereof are formed are disclosed. The reclosable bags 2001 are made from base web material that has transversely applied fastener tape segments thereon. The web material is used in a vertical form, fill and seal bag forming method. The method includes the steps of supplying a continuous strip of tape, having male and female fasteners profiler across the web for sealing thereon. In one embodiment a continuous strip of barrier material, and a continuous strip of fastener having first and second interlocked fastener profile strips are positioned on the continuous strip of tape; and secured thereon, the barrier tape is folded to obtain a fold and two opposing barrier tape fastener strip connecting portions; and, the fold is slit to form two separate continuous strips of barrier material strips and two continuous strips of tape. In another embodiment a coating is applied to the tape itself to prevent sealing of the folded slit tape to itself. The resulting tape and fastener are cut 220 and portioned properly on the web by the unique vacuum belt system of the present invention and by the interconnected tape drive, web drive and the connection to the form fill seal machine.
