Patent Summary
A gas-tight packaging comprises at least one piece of coated paper consisting of a base paper and at least three sequential coatings. Starting from the base paper, the coatings comprise a first barrier layer of at least one hydrophobic polymer, a second barrier layer of at least one hydrophilic polymer, and a third barrier layer of at least one hydrophobic polymer. The packaging is characterized by a precoat situated between the base paper and the first barrier layer, which comprises at least one inorganic pigment and a polymeric binder. The structure is designed to reduce or prevent the transfer of substances, particularly hydrophobic substances, between the barrier layers and is suitable for packaging oxidation-sensitive, moist, and fatty products.
