unfoldable
Able to spread
Unfoldable describes something that can be unfolded or opened out from a folded state: an unfoldable map, unfoldable camping chairs.
Less commonly, it means the opposite—incapable of being folded: The rigid panel was unfoldable.
Context usually clarifies which sense applies.
In mathematics and origami, unfoldable refers to shapes or structures that can be flattened into a plane.
