A zipper tape includes a pair of belt-shaped bases bondable to a film of a bag body, and mutually engageable engagement portion each integrally provided to corresponding one of the belt-shaped bases. One of the belt-shaped bases includes at least two portions having different bonding strengths to the film on a side opposite a side provided with the engagement portion and between an edge of the one of the belt-shaped bases in a width direction orthogonal to a longitudinal direction to a point at which the engagement portions are provided. A bonding strength of a first portion of the at least two portions to the film may be larger than a bonding strength of a second portion to the film.

A slider garage includes an overmolded body, the overmolded body oriented on a zipper, the overmolded body including an overmolded male portion and an overmolded female portion, the overmolded male and female portions positioned on an end of the zipper, such that each is on one side of the zipper, the overmolded male portion being shaped such that it fits in the overmolded female portion in a watertight fashion. Optionally, the zipper includes a male side and a female side, and the overmolded male portion is positioned on the male side of the zipper and the overmolded female portion is positioned on the female side of the zipper.

A reclosable fastener strip includes first and second strip halves each having a strip body and two hook units. Each hook unit has at least one pair of elongated hooks formed on a major surface of the strip body and cooperatively defining a recess therebetween. Each elongated hook is configured and dimensioned to permit being fitted securely in the recess of a corresponding pair of the elongated hooks so as to provide a suitable watertight seal.

A male belt-shaped base having a male member with a short width, and a separation strip are heat-sealed to a film. A female belt-shaped base having a female member with a long width is heat-sealed at a predetermined position so that the male portion and the female portion are at engageable positions. The film is layered and suitably sealed to form a zipper-tape bag. The film and the separation strip are cut to form a cut portion at a non-bonded region in which the film of the zipper-tape bag is not bonded, thereby forming an unsealing tab. The unsealing tab can be easily formed by simply cutting the film.

A magnetic zipper includes two elongate units, each attached to edges of material. One elongate unit includes a series of magnets positioned within a tube. The other elongate unit includes a ferromagnetic material that is attracted by the magnetic field of the series of magnets in the other elongate unit. The ferromagnetic material may also be positioned with a tube. The magnetic attraction between the two elongate units allows them to join to bring the edges of material together and be held together by the strength of the magnetic force.
