A water-tight and gas-tight zip fastener with a sealing port and a method for forming the same provides a zip fastener made of plastic in which preferably spirals in a spiral zip fastener are injection molded with a thermoplastic elastomer which forms a continuously contoured coating, bearing directly on the contiguous edges of the zip fastener strips, and when the zip fastener is closed, the coatings are under compression and form a contiguous seal with each other and to the zip fastener slide to prevent undesirable gas and water penetration. |
