ABSTRACT:
This unitary package is double-walled, the inner wall being capable of conforming to articles within the package, and the space between the walls being occupied by expandable polystyrene. After contents are sealed within the package the entire package is radio-frequency-irradiated, causing the polystyrene to expand into an impact-absorbing foam. During expansion the polystyrene forces the inner wall conformingly against the contents, and the outer wall to become generally convex outward or if constrained to assume the shape of its constraints. The result is a stiff, impact-absorbing pod whose interior surfaces closely conform to the contents.
Multilayer walls of various specified materials, and certain additives to the styrene, are provided to facilitate use of the invention.
