[...] I suspect that there is an error lurking. You can have 'Vacuum
Formed Plastics' which is essentially a sheet of plastics material
that has been heated and formed to a shape. Typically this would
include sandwich trays, or the trays inside a box of chocolates into
which each chocolate goes.

The alternative is 'Foamed Plastics' which are plastics which are
made into a foam in the manufacturing process.

The description you give sounds as though it is a 'foamed' material
but as there are many different chemical types it is not possible to
make any conservation comments, apart from, 'identify the material
