  • Publication number: 20200024059
    Abstract: An inflatable protective packaging unit and associated inflation systems are disclosed. The unit can include an inflatable component that includes overlaid flexible plies connected to each other to define a fluid chamber therebetween. The inflatable component can define an inflation region in fluid communication with the fluid chamber to allow fluid from the inflation region into the fluid chamber. The unit can further include a receiver separably attached to the inflatable component at the inflation region and configured to direct fluid into the inflation region. The inflation system can be configured to discretely engage the inflatable protective packaging unit and provide fluid for inflation.

  • Publication number: 20190240945
    Abstract: 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.

  • Patent number: 10369760
    Abstract: 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.

  • Publication number: 20190202651
    Abstract: 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.
