Shipping container having fiberglass frame

ActiveUS12623837B2Large containersDunnageVertical edge
A fiberglass frame for a shipping container supports dunnage or other support members for separating parts. The fiberglass frame comprises four hollow vertical edge members made of fiberglass, each extending between corner assemblies. The fiberglass frame further comprises a roof and a base each made of hollow fiberglass members. Each hollow fiberglass member extends between two corner assemblies. The corner assemblies are also made of fiberglass. The inherent lack of electrical conductivity in the frame prevents sensitive parts shipped in the dunnage or other support members from being damaged or compromised.

Machine and method for producing dunnage having an x-shaped cross-section profile

ActiveUS12583199B2Paper/cardboard articlesDunnageFree edge
A dunnage conversion machine includes a bunching assembly that randomly crumples at least two plies of sheet stock material into modified plies having a relatively thicker three-dimensional shape, and a feeding assembly that advances and connects together longitudinally-extending portions of the modified plies to form a dunnage strip.

Dunnage bag with graduated inflation stripes

PendingUS20250303952A1Load securingTransportation itemsDunnagePhysics
A dunnage bag may have stripes on its sides that extend from a top edge to a bottom edge of the bag. When the bag is inflated, one or more of the stripes may be visible to a user viewing an end of the bag. A number and width of stripes visible to a user may indicate a width of the dunnage bag, a corresponding width of the gap within which the bag is positioned, and an amount the bag that is in contact with surfaces of adjacent cargo. The user may note an outermost visible and determine that the bag has a width within a range of widths associated with such outermost visible stripe, and whether such width allows for the bag to be used safely. If a stop stripe is visible, the gap is too wide for the bag.
