An air bag packaging arrangement and a self-adhesive checking valve, the air bag packaging arrangement includes an air bag and an air valve which is the self-adhesive checking valve. The air bag includes first and second cell overlapped layers to form an air chamber and a valve opening. The air valve includes first and second sealing films overlapped between the first and second cell layers, and a strengthening film provided between the first valve film and the first cell film to strengthen a joint strength between the first valve film and the first cell film, so as to prevent the first valve film from being broken, so as to further avoid an air leakage.

Disclosed herein are processes for production of a cured polymeric product which processes include using rubber particles to form a rubber layer, applying liquid binder to form a bound layer from the rubber layer, and curing, whereby repetition of steps allows for formation of additional layers and ultimately production of the cured polymeric product.

The present disclosure is directed to dunnage bags formed using polyethylene terephthalate (PET) and processes for manufacturing these PET dunnage bags. Generally, the PET dunnage bags of the present disclosure include a PET outer bag, an inner bladder enclosed within the PET outer bag, and a valve assembly that enables air to be introduced into (or escape out of) the inner bladder to inflate (or deflate) the inner bladder, thereby inflating (or deflating) the PET dunnage bag.

A system and method for forming a seam in at least one piece of material used to form an inflatable product utilizes a seam forming member that is attached to an inside wall of a piece of product material that comprises the inflatable product. The inflatable product is comprised of one or more pieces of product material and one or more seam forming members located at any location where a seam is necessary. A first portion of the seam forming member attaches to a first edge of a first piece of product material and a second portion of the seam forming member attaches proximate a second edge of the first piece of product material. The seal forming means can be accomplished by radio frequency, ultrasonic, heat or other types of welding, and adhesive or chemical based bonding.

A balloon valve and pouch assembly 1 is mounted in a neck portion of a balloon and comprises a balloon valve 2 and a pouch 3. The pouch 3 is adapted to receive and retain an illumination device 100 in a predetermined position. The valve 2 has a valve inlet 2A and a valve outlet 2B provided at an opposite end of the valve 2. The valve 2 is delimited by sealing path 4 and layers 2C, 2D. The pouch 3 comprises an opening 3A through which an illumination device 100 can be inserted and a closed opposite end of the pouch 3B. The pouch 3 is delimited by the first sealing path 5 and layers 3C, 3D. The layers 3C, 3D are heat-sealed together along a first sealing path 5, which is substantially V-shaped, with the open end of the V-shape defining the pouch opening 3A and the closed end of the V-shape defining the closed end of the pouch 3B.

A method of manufacturing a stitchless sportsball includes the steps of: forming an integrated ball bladder; pre-making an integrated ball cover; cutting the integrated ball cover into a plurality of ball panels; and adhering the ball panels onto an outer spherical surface of the integrated ball bladder for encasing the integrated ball bladder within the integrated ball cover to form a sportsball and to form a plurality of ball channels on the sportsball. The integrated ball bladder includes an inflatable bladder encased in a reinforcing carcass in a stitch-less manner, wherein the inflatable bladder is vulcanized and integrally bonded with the reinforcing carcass for forming the integrated ball bladder in order to enhance a strength and roundness of the integrated ball bladder.

A machine for converting two different types of webs of inflatable material to two different types of inflated cushioning material includes an inflation arrangement, a sealing arrangement, and a tensioning device. The inflation arrangement is configured to provide air at a lower pressure to a first web of a first type of inflatable material to inflate the first type of inflatable material, and to provide air at a higher pressure to a second type of inflatable material to inflate the second type of inflatable material. The inflation arrangement includes a guide pin configured to the first and second webs and align the first and second webs on the machine. The sealing arrangement is configured to seal the first type of inflatable material and the second type of inflatable material to create the two different types of inflated cushioning material. The tensioning device is configured to provide a lower tensioning force to the first web as the first web moves between the inflation arrangement and the sealing arrangement, and to provide a higher tensioning force to the second web as the second web moves between the inflation arrangement and the sealing arrangement.
