摘要:
The present disclosure relates to a high burst slider zipper which allows for bottom filling of reclosable packages, such as large bags, and further provides increased resistance to damage from the dropping or shock loading of the filled package. This is achieved by providing a peel seal or other frangible or separable connection between the zipper profiles, and by sealing a portion of one of the flanges to itself by a hard seal above the peel seal. This causes the external forces on a bag from bottom filling or shock loading to be directed toward the hard seal and further directed so as to cause a shear force against the peel seal, thereby increasing the resistance of the package to external forces.

The present disclosure relates to a high burst closure which allows for bottom filling of packages, such as large bags, and further provides increased resistance to damage from the dropping or shock loading of the filled package. This is achieved by providing profiles that combine an upper portion of one profile and its related flange, so as to form a juncture above a peel seal joining one profile to the other, so that external forces on a package or bag from bottom filling or shock loading are directed toward the juncture thereby causing a shear force against the peel seal or other frangible connection, thereby increasing the resistance of the package to external forces.

The disclosure relates to a method and apparatus for manufacturing a package with a rigid or semi-rigid container and a polymeric or plastic header with a reclosure, such as a zipper. The rigid or semi-rigid container is typically provided in a stack of flat containers. The header is sealed, glued or otherwise secured to the containers. The container, typically inverted, is filled, and the bottom is formed by folding and sealing the bottom portion of the container.

The present disclosure relates to spaced multi-rib zippers, reclosures or closures for flexible packaging, wherein openings or lines of weakness are created between rows of mating elements.
摘要:
Reclosable zippers for reclosable packages are disclosed. The zippers include male and female profiles. The female profiles are periodically inwardly and/or upwardly deformed in order to generate tactile and audible feedback when the zippers are opened or closed by the user. The deformation of the female profiles typically maintains the strength of the zipper.
