Method of making a plastic film with integrated zipper closure, and plastic bag having an integrated zipper closure
A method of manipulating thermoplastic film to create integrated features and particularly relates to an improved method of manufacturing a packaging bag that is reclosable after initial opening. Multiple sections of thermoplastic film are layered on top of themselves to form a multi-layer portion of the thermoplastic film. The multi-layer portion may then be conglomerated into a unitary thicker portion of the film that can then be shaped into a closure strip. In order to form a bag, a second such closure strip may be made. The two closure strips are then aligned and the remaining open portions of the bag are then sealed such that the closure strips form a reclosable opening that may be opened and closed repeatedly.
System and process for making a pouch or container
A system and process for making a container or pouch that separates the cutting and sealing steps into two distinct steps with a separate step of rotating the container or pouch template 90 degrees relative to a direction of travel between the cutting and sealing steps.
Vacuum pouch for athletics
A pouch or pocket may act as a container and may be used to securely hold objects (e.g., cell phone, keys, wallet, etc.) during athletic activity (e.g., running). The pouch may be a standalone item or integrally formed as part of other items. The pouch may hold the object to be stored in place within the pouch or pocket. The pouch may provide some cushioning or impact force attenuation to protect the object being held within the pouch or pocket. Additionally, the pouch may be attached to a garment, such as running clothes. The pouch includes an outer envelope sealable by a closure and a one-way valve with foam layers located inside the pouch. After the object is placed in the pouch, the closure is closed, and the air within the pouch is expelled via the one-way valve by compressing the foam layers from the outside.
Slider insertion apparatus and methods
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.
WASHABLE, WATERPROOF, SEALABLE AND REUSABLE STORAGE BAGS
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.
Method and apparatus for creating pouches or bags with multiphase sealing
A method and apparatus for forming pouches and/or bags is disclosed. A seal and/or insert is crushed using a multiphase sealer or crusher.
Washable, waterproof, sealable and reusable storage bags
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.

Method And System For Forming Packages
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.
Fastener with guide posts and methods therefor
A zipper (100) includes a male closure element (101) and a female closure element (102). The male closure element includes a base member (103), one or more male interlocking members (201,203) extending distally from a first side of the base member, and a plurality of guide posts (105,107) extending from a second side of the base member. The female closure element includes a base member (104), one or more female interlocking members (202,204) extending distally from a first side of the base member, and a plurality of guide posts (106,108) extending from a second side of the base member.
