Process for in situ production of microcapillary dispensing system for flexible pouch

In an embodiment of the present disclosure, a process for producing a flexible pouch is provided. The process includes placing a capillary precursor element (CPE) between two opposing flexible films. The flexible films define a common peripheral edge. The CPE comprises an array of pins sandwiched between two opposing polymeric strips. The process includes positioning a first side of the CPE at a first side of the common peripheral edge and positioning a second side of the CPE at a second side of the common peripheral edge. The process includes first sealing, at a first seal condition, (i) the opposing polymeric strips to each other to form a matrix, and (ii) sealing the matrix to the two opposing flexible films. The process includes removing the array of pins from the matrix to form an in situ microcapillary strip.

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.

Multi-film thermoplastic bags having grab zones with contact areas and methods of making the same

One or more implementations of a multi-film thermoplastic bag with a grab zone of contact areas positioned in a high-touch area of the bag. For example, the multi-film thermoplastic bag includes one or more regions of a first film in contact with a second film at one or more contact areas. The grab zone regions of one or more contact areas are located in visible and high-touch areas to provide visual and tactile cues of strength and durability. Moreover, the grab zone regions of one or more contact areas serve to distribute pull and lift forces across a wider area in order to avoid common failures in high-touch areas such as over stretching, punctures, tears, and rips.

System and method for applying a fastening material to a substrate
