PACKAGE COMPRISING RELATIVE DRY MATERIAL CONTAINING LESS THAN 20 WT% OF WATER AND METHODS FOR ITS PRODUCTION AND USE Russian patent published in 2016 - IPC B65D51/24 

FIELD: food industry; packaging industry.

SUBSTANCE: container (2) for food products contains rigid box (4) from thermoformed polymeric material, which stores dry food product (6) and which is covered by detachable cover (8) from film. Film (8) contains hydride, which is capable to extract hydrogen in contact with moisture. Besides, film (8) has relatively high permeability for water vapour and relatively low permeability for gaseous hydrogen. During use water vapour from air surrounding container (2), enters into film (8) and reacts with hydride with formation of hydrogen.

EFFECT: due to relatively low hydrogen permeability of film (8) possibility of evaporation of hydrogen from container is limited; instead, hydrogen reacts with oxygen in container, in reaction catalysed by catalyst contained in box (4), due to which contained in container (2) oxygen is removed, and food product (6) is protected against oxidation.
