An inflatable packaging structure, including at least one inflatable panel made of a plurality of layers of thermoplastic material, the at least one inflatable panel includes a plurality of fluid chambers, whereas a one-way check valve is incorporated into at least one of the plurality of fluid chambers, an air supply line, configured to commonly communicate with each of the one-way check valves to supply fluid into the fluid chambers; and at least two heat sealed edges formed on the at least one inflatable panel, each of which is configured to attach a portion of the at least one inflatable panel to another portion thereof; and wherein the at least two heat sealed edges extend generally in parallel with respect to each other and configured to form the inflatable packaging structure with at least partially rectangular cross-section, having at least four faces.

A machine converts a web of preformed pouches, which are defined by transverse seals extending from a remote edge, into inflated dunnage units. A sealing arrangement is positioned to provide a longitudinal seal intersecting the transverse seals to close the preformed pouches and form a dunnage unit. The sealing arrangement has at least two sealing belts. Each belt is positioned so that respective first sides engage a surface of the web and pull the web through sealing elements positioned on either side of the web. A heating element is on a second side of the first belt not engaging the web. A compliant material is on a second side of the second belt not engaging the web. As the web passes between the heating element and compliant material, imperfections in the web are smoothed by the compliant material and the layers of the web are sealed by the heating element.

The present disclosure relates generally to an inflation and sealing machine and in particular to a method for modifying one or more parameters of the machine. The method includes identifying a configuration of a supply material to be used with the inflation and sealing machine, such as by receiving a user input, automatically detecting characteristics of the material, and/or receiving data such as from a sensor regarding the characteristics of the material. Once the configuration of the supply material is identified, the method includes receiving a selection of a prestored recipe according to a configuration of the supply material, where the recipe determines or sets the value for one or more operating parameters of the machine.

A sealing device generally includes a rotatable support cylinder having an outer, circumferential surface and a heating element disposed about such surface and secured thereto such that the heating element rotates therewith. The heating element is coiled about the outer surface of the cylinder in the form of an overlapping helical pattern. Juxtaposed film plies may be sealed together by bringing the sealing device into rotational contact with the juxtaposed film plies and heating the heating element to a temperature sufficient to cause the film plies to seal together.

Provided is a protective packaging formation device for sealing a flexible web. The device includes a housing having multiple housing supports disposed to collectively define different support plane areas for contact with an underlying surface. The housing is positionable in a multiple different dispensing orientations by placing the housing in different housing supports. The device also includes a web support depending from the housing. The web support includes a one end positioned distally from the housing and a second end positioned proximal to the housing. The web support supports a supply of a flexible web in a position extending from the housing beyond the housing support. The device also includes an adjustable stand connected to one end of the web support and extending down to the underlying surface such that the stand limits the tilting of the housing in the direction in which the web support extends from the housing.

A protective packaging formation device is provided herein. The device includes an inflation assembly having a fluid conduit that directs fluid between overlapping plies of a polymeric web. The device also includes a driving mechanism that drives the film in a downstream direction. The device also includes a sealing mechanism that includes a thin film heater that heats the plies to create a longitudinal seal that seals the plies of film together. The driving mechanism drives the web such that the web slides across the heating assembly in a downstream direction to trap fluid between the plies.

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.

A transfer and dispensing apparatus is disclosed for the conveying and separation of packaging material, cushions or pillows when needed by the operator. When a packer working over a conveyor receives a box that requires void fill, an operating switch such as a foot pedal is depressed to dispense pillows from the apparatus and into the box in a connected strip. When the operating switch is released, the apparatus stops dispensing pillows, separates the continuous strip of pillows along a transverse perforation in the strip, and ejects the end of the separated segment. The packer can then complete packing the box by placing the severed end of the pillows into the box, advance to the next box, and repeat the process. The transfer and dispensing apparatus may be positioned in any convenient location including adjacent to, above or attached to the inflation 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.
