A fluid-impervious slide fastener is disposed; an covering abutting member is formed in a central slit of a pair of support tapes, the covering abutting member has a first covering body having a covering layer and a second covering body having a covering layer; when the fluid-impervious slide fastener is in a coupled status, the first covering body and the second covering body are able to elastically abut against each other so as to form a tightening deformation, thus the central slit is provided with a fluid-impervious function against a fluid, for example a liquid, of capable of bearing a hydrostatic pressure of 30 gf/cm.sup.2.

An interconnection sheet is arranged which is separate to a rear stop. At least one second securement hole in at least one of left and right waterproof tapes is not covered by the interconnection sheet, and a rear stop is arranged to fill the at least one second securement hole.

Through-holes are formed at a constant pitch along a side-edge portion of a fastener tape where a tape base fabric is covered by a waterproof layer, the through-holes piercing the fastener tape. Plasma treatment or corona treatment is applied to the side-edge portion of the fastener tape so as to form an activation region on a surface of the waterproof layer on one or both sides of the fastener tape. Injection molding of fastener elements is performed to attach the fastener elements to the side-edge portion of the fastener tape. Melted resin adheres to the activation region and fills the through-hole before solidifying into the fastener element.

A method of sealing a zipper closure has a first waterproof element in the form of a sealing zone base and a second waterproof element in the form of a waterproof interlocking zipper fastener. The first waterproof element and the second waterproof element are placed in overlapping engagement to define a sealing zone. One or more sealing elements are placed in the sealing zone to prevent leakage.
