ABSTRACT:
The present invention includes methods, an apparatus and a system in which reclosable bags and components thereof are formed. The reclosable bags 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 first and second closure elements sealed thereon. The first and second closure elements have respectively a pair of male profiles and a pair of female or u-shaped elements thereon, each shaped for interlocking with the other. A thickened sealing bridge between the male elements and a second thickened sealing bridge between the female elements allows precise sealing of the fastener element to fastener tape or to the bag walls as desired. It also facilitates keeping the profiles interlocked.
