ABSTRACT A unitary protective envelope device for packaging fragile articles has an outer wall and a conformable inner wall. A mass of compressed resilient open-celled cellular material is enclosed in the space between the walls and held in compressed condition under vacuum. The material upon exposure to atmospheric pressure expands, forcing the inner wall conformingly against articles in the envelope and converting the envelope into an impact-absorbing pod embracing and conforming closely to its contents. In one preferred embodiment a compressed slab of open-celled foam held in compressed condition in a vacuum-sealed sack positioned between the walls expands to embrace the contents of the envelope when the sack is punctured.
