摘要:
The disclosure pertains to method for manufacturing reclosable packages, bags or pouches wherein, typically, a unisex zipper is looped and sealed inside of the package. The formation of the looped zipper segment causes the package to have a wide open mouth, and a natural tendency toward the open configuration. Both transverse and machine direction methods are disclosed, as well as resulting packages which may include a spout.
摘要:
The present disclosure relates to a method for producing 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.
摘要:
The disclosure relates to a zipper for a reclosable bag wherein the zipper is designed to make additional sound during operation, and further provide an increased tactile response. The zipper profile is manufactured by forming cuts in the profile, and then the profile is stretched so that the cuts become gaps. These gaps cause additional sound during operation of the zipper.
摘要:
The disclosure relates to relates to the use of trim sensors, registration sensors or pressure sensors to sense the position of a zipper during the manufacture of reclosable packages, particularly manufacturing processes wherein the ends of the zipper need to line up at the fin seal to insure success of the closure. The output of the sensors is used to adjust belt or roller speeds, or similar operational parameters to bring the zipper profiles into alignment at the fin seal.
摘要:
A reclosable zipper is disclosed which includes a first profile containing a first interlocking element and a first product side flange. A second profile is provided which contains a second product side flange and a second interlocking element for reclosably interlocking with the first interlocking element. A sachet is provided on a flange either on the product or consumer side or extending between the first and second flanges.
摘要:
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.
