Estimating the term…
Flowable loose packing dunnage is formed from paperboard into three dimensional particles of various shapes. Also, an apparatus for forming the dunnage employs two vertically aligned arrays of toothed, untoothed and/or cutting wheels through the nip of which paperboard segments pass and by which they are shaped into dunnage particles. Further, in a method of forming the dunnage particles, strips of paperboard are cut into segments which are formed into three dimensional shapes. A method of protecting a packed object surrounds it with the flowable loose packing dunnage made of paperboard in accordance with the present invention.
Flowable loose packing dunnage comprising multiple particles, said particles including a particle being made of a single sheet of paperboard formed into a non-planar shape which includes an integral reinforcing structure which helps maintain the shape of the particle, said reinforcing structure including either or both of a strut or an elongated region of narrowed thickness of the paperboard.
Flowable loose packing dunnage comprising multiple particles, said particles including a particle being made of paperboard formed into a non-planar shape, said shape including at least a pair of adjacent out-of-phase undulating strips.
Flowable loose packing dunnage comprising multiple particles, said particles including a particle being made of paperboard formed into an undulating shape which includes a rise and a fall, wherein a strut extends between said rise and said fall.
Flowable loose packing dunnage comprising multiple particles, said particles including a particle being made of paperboard formed into an undulating shape having an elongated region of narrowed thickness to enhance shape retention, strength and resiliency.
Flowable loose packing dunnage comprising multiple particles, said particles including a particle being made of paperboard formed into a non-planar shape, wherein said shape is that of a strip bent at least once to form at least two approximately perpendicular legs and wherein a strut extends between said at least two of said legs.
Flowable loose packing dunnage comprising multiple particles, said particles including a particle being made of paperboard formed into a non-planar shape, wherein said shape is that of a segment bent at least once to form at least two legs and wherein the segment has an elongated region of narrowed thickness.
Flowable loose packing dunnage comprising multiple particles, said particles including a particle being made of paperboard formed into a non-planar shape, wherein said shape is an enclosure having three or more sides and wherein a strut extends between two of said legs.
Flowable loose packing dunnage comprising multiple particles, said particles including a particle being made of paperboard having an elongated region of narrowed thickness and being formed into a cylindrical shape such that the elongated region of narrowed thickness is circumferentially oriented relative to the cylindrical shade.
Flowable loose packing dunnage comprising multiple particles, said particles including a particle being made of paperboard having an elongated region of narrowed thickness and being formed into a helical shape such that the elongated region of narrowed thickness is circumferentially oriented relative to the helical shade.
