Abstract
A material for food packaging, includes a polystyrene and 0.1 to 50% by weight of a halloysite essentially in the form of empty nanotubes, relative to the weight of the material, a method for preparing such a material, as well as the applications of this material, in particular for the manufacture of a food packaging.
Claims12
A food packaging comprising a material for food packaging, the material comprising:
- a polystyrene and 0.1 to 50% by weight of a halloysite essentially in the form of empty nanotubes, relative to the weight of the material, wherein
- the polystyrene comprises styrene tetramer and optionally styrene monomer, styrene dimer and styrene trimer,
- the styrene tetramer weight content being higher than the styrene monomer content, and
- the styrene tetramer weight content being higher than the total weight content of styrene monomer+styrene dimer+styrene trimer.
