摘要： A system and method for forming reinforced packages. The method can comprise forming an attached web by adhering a construct to a web of material, and moving the attached web in a downstream direction through at least a web edge forming assembly. The moving the attached web can comprise moving the construct with the web of material. The method further can include at least partially forming a folded web by folding at least a portion of the web of material as the attached web moves through the web folding assembly and forming a reinforced package comprising a liner and the construct by separating the liner from a remainder of the folded web. The construct is adhered to the liner.

摘要： The present invention is a bag making machine (20, 30). The bag making machine (20, 30) includes: a conveying unit (37) which conveys a multi-layer film (S) in which films (13a, 13b) are overlapped; a side edge sealing device (27) which thermally fuses the films (13a, 13b) to each other; and an ultrasonic device (26) which crushes a part of a zipper member (14) disposed between films (13a, 13b). The side edge sealing device (27) includes: a platform (44); and a heat-generating head (45). The ultrasonic device (26) includes: an anvil (41); and an ultrasonic horn head (42). The heating-generating head (45) and the ultrasonic horn head (42) reciprocate at a same cycle via a link member (51).

摘要： A light-absorbing layer and a bonding layer are layered on a first side of each of a belt-shaped male base portion integrated with a male portion and a female base portion integrated with a female portion on a side of the male and female base portions opposite the first side. The light-absorbing layer contains a light-absorbing material having a wavelength absorption range from 800 nm to 1200 nm to absorb a laser beam of the range. The bonding layer contains a low-melting-point resin in a form of a metallocene linear low-density polyethylene having a melting point ranging from 60 degrees C. to 120 degrees C. When the zipper tape is bonded to the base film, the laser beam is applied to heat the light-absorbing layer to melt the bonding layer. The melted bonding layer is pressure-bonded to the base film. The base film can be bonded without causing thermal degradation.

摘要： Embodiments of the present disclosure describe a method and apparatus for a resealable package having an internal zipper seal. In one embodiment, the apparatus is a vertical form, fill, and seal machine that includes a former, a vertical sealer, and a zipper separation blade located between the former and the vertical sealer. The zipper separation blade further comprises a connector and a blade body that defines a zipper gap between an exterior surface of the former and the blade body.

摘要： An apparatus and method for operably mounting a slider onto a recloseable plastic zipper closure includes a rotor having at least one slider-engaging shoulder; an insertion wedge adjacent to the rotor and sized to slidably accommodate the slider for mounting onto a zipper closure; and a zipper guide member adjacent to the rotor and adjacent to the insertion wedge for guiding and holding a zipper closure while the slider is mounted thereon. The insertion wedge will have a leading edge and a trailing edge and increase in thickness from the leading edge to the trailing edge. The apparatus can be vertically oriented or horizontally oriented.

摘要： 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.

摘要： Disclosed are embodiments of a versatile storage bag and methods of making same. The versatile storage bag may have first and second sidewalls, a double-locking closure mechanism with a first closure element extending along the first sidewall and a second closure element extending along the second sidewall, each closure element having a channel and an elongated member configured for interlocking with one another. A double-seal along three sides of the first sidewall and the second sidewall form a gusset between two seals, leaving an opening through the double-locking closure mechanism. Corner seals may be formed at the corners of the first and second sidewalls, further reinforcing the double-locking closure mechanism for an airtight and hence waterproof seal. The versatile storage bag may be made of a food-grade polyethylene vinyl acetate blend, approximately 90% or less ethylene vinyl acetate and approximately 10% or less polyethylene.
