Abstract
A web, method, and apparatus for forming dunnage units. The web includes first and second elongated layers. A plurality of seals that hermetically join the first elongated layer to the second elongated layer to form a plurality of inflatable pouches and an inflation channel that is in fluid communication with pouches and is disposed outside of the pouches. An inflation side line of perforations, a gap forming area, and an opposite side line of perforations are arranged in a line between pair(s) of the pouches.
Claims14
A web for forming dunnage units, comprising:
- a first elongated layer;
- a second elongated layer superposed over the first elongated layer;
- a plurality of seals that hermetically join the first elongated layer to the second elongated layer to form a plurality of inflatable pouches and an inflation channel that is in fluid communication with pouches and is disposed outside of said pouches, wherein the pouches include a mouth portion and an elongated tube portion, wherein a width of the elongated tube portion is wider than a width of the mouth portion, and wherein the mouth portion is divided into multiple ports;
- an inflation side line of perforations through the first and second layers, between at least one pair of adjacent pouches;
- a gap forming area defined in the first and second layers, between the at least one pair of adjacent pouches, wherein a start of the gap forming area is aligned with a transition from the width of the mouth portion to the width of the elongated tube portion;
- an opposite side line of perforations through the first and second layers, between the at least one pair of adjacent pouches;
- wherein the inflation side line of perforations, the gap forming area, and the opposite side line of perforations are arranged in a line,
- wherein the inflation side line of perforations has a length that extends from the inflation channel to the gap forming area, and the gap forming area has a length that extends from the inflation side line of perforations to the opposite side line of perforations;
- and
- wherein a length of the opposite side line of perforations is at least three times as long as a length of the gap forming area.

- wherein the pouches include a mouth portion and an elongated tube portion, wherein a width of the elongated tube portion is wider than a width of the mouth portion, and wherein the mouth portion is divided into multiple ports;
- an inflation side line of perforations through the first and second layers between at least one pair of adjacent pouches;
- a gap forming area defined in the first and second layers between the at least one pair of adjacent pouches;
- and
- an opposite side line of perforations through the first and second layers between the at least one pair of adjacent pouches;
- wherein the inflation side line of perforations, the gap forming area, and the opposite side line of perforations are arranged in a line;
- wherein the inflation side line of perforations has a length that extends from the inflation channel to the gap forming area, and the gap forming area has a length that extends from the inflation side line of perforations to the opposite side line of perforations;
- wherein an end of the gap forming area is aligned with a transition from the width of the mouth portion to the width of the elongated tube portion of the pouch.

- an opposite side line of perforations through the first and second layers, between the at least one pair of adjacent pouches;
- wherein the inflation side line of perforations, the gap forming area, and the opposite side line of perforations are arranged in a line;
- wherein the inflation side line of perforations has a length that extends from the inflation channel to the gap forming area, the gap forming area has a length that extends from the inflation side line of perforations to the opposite side line of perforations, and a length of the opposite side line of perforations is at least three times as long as a length of the gap forming area;
- and
- wherein the gap forming area comprises a line of perforations that is weaker than the inflation side line of perforations and the opposite side line of perforations.
