A rectangular air packaging device and a manufacturing method therefor are provided. The device includes at least one inflatable main body and at least one inflation valve. The inflatable main body includes a plurality of inflation units. Each inflation unit has an inflation chamber. The inflation valve communicates with the inflation chamber, so as to inflate the inflation unit. After being bended and heat-sealed, the inflation units form a plurality of side walls. Two adjacent side walls of the side walls are arranged roughly with a right angle, so that the side walls form a rectangular containing cavity, so as to contain item to be packaged and to provide air cushioning effect to the item to be packaged.

A method of making an inflatable panel that includes the steps of: superimposing a second layer of a material of low gas permeability upon a first layer of a material of low gas permeability; creating a plurality of first elongated seals by intermittently sealing together the first and second layers, thereby defining a plurality of first tubes between adjacent pairs of the first elongated seals. The method also includes sealing rear ends of the first tubes; inflating the first tubes from front ends thereof with a gas; and then sealing the front ends of the first tubes, such that the gas within each of said tubes is prevented from flowing between the first tubes.

An inflatable corner packing device for protecting corners of a product includes: first and second thermoplastic films having a first section, a second section, and an elbow section connecting the first and second sections in a vertical direction, wherein a plurality of fluid containers each extending in the vertical direction, and the first and second sections and the elbow section each have a right side portion, a left side portion, and a middle portion connecting the right and left side portions, wherein the side portions are inwardly crooked for holding a product therebetween. The first and second thermoplastic films are folded, and the folded films are bonded in the elbow section along a border between adjacent fluid containers in each crooked side portion, leaving a remaining portion of the border unbonded, so that the bonded borders form the elbow section.

In a method of making packages, a web of preformed inflatable bags is moved along a path of travel. The preformed inflatable bags include two inflatable panels, and each inflatable panel includes a first ply and a second ply that are sealed together to form an inflation pattern. Each of the preformed inflatable bags are inflated and sealed across the seals of the inflation pattern. A product is deposited into each of the preformed inflatable bags, either before or after the inflation and/or sealing. Each of the preformed inflatable bags and contained product are loaded into a non-inflatable bag.

An air-sealed body capable of automatically opening an air valve is provided. First, the two inner films are laminated between two outer films. An air passage and a plurality of air columns are formed through joining by means of heat-sealing. Air inlets are formed by heat-sealing in the two inner films at the places where the heat-resisting material is coated, and a plurality of heat-sealed blocks are formed through joining by means of heat-sealing at the sides of the air inlets. When air is filled in, the two outer films of the air passage are pulled open outward in a longitudinal direction, the air passage contracts in a lateral direction due to a drop height of the heat-sealed blocks. The two inner films are squeezed by the heat-sealed blocks to be pulled open outward in the longitudinal direction to open the air inlet.

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.

A multilayer staggered laminated air packaging device and a producing method therefor. said staggered laminated air packaging device comprises two or more layers of inflatable packaging bodies arranged in stack, a receiving chamber for storing articles to be packaged is formed by said inflatable packaging body which is located at said inner side, and said two or more layers of inflatable packaging bodies each comprise one or more inflatable subunits, wherein at least one inflatable subunit of at least one layer of said inflatable packaging body is arranged in a stack staggered relative to at least one inflatable subunit corresponding to said other layer of said inflatable packaging body in said two or more layers of inflatable packaging bodies, so as to improve said damping performance of said staggered laminated air packaging device.

The present disclosure is directed to an inflatable-cushion inflation and sealing device. The device includes an inflation assembly configured for insertion between first and second overlapping film plies. The inflation assembly includes a fluid conduit configured to direct a fluid in between the plies to form one or more cushions. The fluid conduit includes a nozzle. The inflation assembly includes a cutting member. The cutting member includes a blade holder with a blade and a blade guard mounted thereon. The blade guard has a safety position in which the blade is covered and a retracted position in which the blade is exposed. Installation of the blade holder onto the inflation assembly automatically positions the blade in the working position with the blade guard retracted. Removing the tray from the inflation assembly automatically positions the blade in the safety position by covering the blade with the blade guard.

An inflatable pouch includes a bladder formed from an inflatable web and an outer skin formed from a film. The bladder includes a bladder pouch that includes a bottom portion at a folded edge of the inflatable web, front and back portions on either side of the folded edge, and sides where the front and back portions are sealed to each other. The outer skin includes an outer skin pouch that includes a bottom portion at a folded edge of the film, front and back portions on either side of the folded edge, and sides where the front and back portions are attached to each other. The bladder is attached to the outer skin at a tack area such that the sides of the bladder pouch and the outer skin pouch are not directly attached to the sides of the outer skin pouch.

A collapsible container includes an airflow input valve operably connected to one or more bladders on the inside surface of the container via an airflow network.
