An appliance is provided that is able to vacuum and heat seal plastic bag members containing liquids such as sauces and soups. The appliance may take on a uniquely shaped profile to allow the liquid to sit upright within a bag during the vacuuming process. The appliance also preferably includes a pressure sensor to constantly monitor pressure inside of the bag during the vacuum and sealing process. This may help to prevent liquid from being sucked up and into the appliance.

A method and apparatus for manufacturing a double bag (20) are disclosed. The method comprises placing an inner bag (30) in an outer bag (40) through an open top end (42), inserting a gas feeding tube (50) between through the open top end (42), feeding a head space (44) between the inner bag (30) and the outer bag (40) with an inert gas through the gas feeding tube (50), extracting the gas feeding tube (50), and sealing the top end (42). A gas box (80) surrounds the open top end (42) to reduce the risk of oxygen entering the head space (44).

A shipping system for shipping planar substrates includes a plurality of planar substrates stacked to form a pack and a plurality of interleaving material including substantially spherical beads positioned between the substrates of the pack and configured to carry a load. Substantially all of the beads have a diameter within 25% of D.sub.max, where D.sub.max is a diameter corresponding to a size of an opening of an upper limit sieve used in the shipping system. Also disclosed are a spacer for use in a shipping system for shipping planar substrates, a wrapped system for shipping planar substrates, a method of wrapping a system for shipping planar substrates, and a powder applicator.

A gas-sealed body with cushioning function is adapted to be inflated by a processing machine. The processing machine includes an inflation bar and pressing wheels adjacent to the inflation bar. The inflation bar is to inflate the gas-sealed body. The pressing wheels roll on a rolling track of the gas-sealed body for conveying the gas-sealed body. The gas-sealed body includes an inflation channel, gas inlets, pillow structures, and gas chambers. Each gas chamber includes one or more gas inlets, one or more cushion-part gas column, and a main-part gas column. When each of the inflation inlets is inflated, the corresponding one or more cushion-part gas column and the corresponding main-part gas column are inflated and expanded in order.

A method and device for sealing gas in a gas compartment-equipped bag, in which pressurized gas discharge outlets are provided in the distal ends of a horn and an anvil of an ultrasonic sealing device, and such horn and anvil used for ultrasonic sealing are also used as gas-discharging nozzles. The distal ends of the horn and the anvil are placed against a cutout of a gas compartment of a bag, a gas is discharged into the gas compartment from the discharge outlets, the films surrounding the cutout are being clamped by the horn and the anvil while gas discharging is in progress, and then the gas compartment is ultrasonically sealed by the horn and the anvil to trap the gas inside.
