The reclosable back-seam bag includes a reclosable fastener that includes two ends, a first continuous elongated profile strip having a front wall connecting flange and a second continuous elongated profile strip having a back wall connecting flange. The first continuous elongated profile strip includes a male interlocking profile having at least one male interlocking member, and the second continuous elongated profile strip includes a female interlocking profile having at least one female interlocking member. The male interlocking member is configured so as to cause the male interlocking profile to be separated from the female interlocking profile with a substantially equal opening force when being separated in a direction toward said top seal as when separated in a direction toward said bottom seal.

Abstract: A fastener profile assembly and method of forming a fastener profile assembly is provided. The assembly includes a continuous supply of two interlocking profiles which are sealed at either end with a compression molded segment seal. The compression molded segment seal is formed through the application of heat and pressure to the interlocking profiles, thereby fusing the area and forming one end of the profile. Advancement of the profiles and application of heat and pressure to a second area forms the second end of the profile assembly. Manufacture of a fastener in such a manner allows for highly automated profile production with precise, accurate registration of the fastener profile.

Each protuberance, as extruded, has a rounded tip, a concave or partial-concave tail, and a generally upstanding neck portion connecting the tip and tail. The profile strips are readily secured to the web without entrapping air between the profile strips and the film web and form an vacuum tight seal. The interlocking hooks, recesses and protuberances are sized, constructed and arranged to provide a vacuum tight seal upon interconnection thereof.

Abstract: A reclosable zipper strip is dispensed through a feeding mechanism and, when an optical sensor detects one of the splotch seal portions of the zipper strip, a desired length of zipper strip is advanced over an elevator platform. A knife is then signaled to descend and sever the advanced portion of zipper strip, which is thus deposited onto the elevator platform. As the selected portion of the zipper strip is being positioned and deposited onto the elevator, the web of flexible film is being positioned above the platform. A sealing head is then positioned over the web of flexible film, while at the same time the elevator platform is driven upwardly so that the zipper strip portion positioned thereon comes into contact with the web of flexible film. The heat passing through the web of flexible film creates an airtight seal of the zipper strip to the web.
