SUBSTANCE: invention relates to a polyamide compound, including polyamide resin and polyamide oligomer, which demonstrates an ability of oxygen absorption. The polyamide compound contains 25-50 mol.% of a diamine unit, which contains an aromatic diamine unit in an amount, equal to 50 mol.% and more; 25-50 mol.% of a dicarboxylic acid unit, which contains a linear aliphatic unit of dicarboxylic acid and/or an aromatic unit of dicarboxylic acid in an amount, totally equal to 50 mol.% and more; and 0.1-50 mol.% of a composite unit, containing tertiary hydrogen. The said polyamide compound has relative viscosity in range from 1.01 to 4.2. The invention also relates to a sheet, a container in the form of a tray or a bowl and a tube, which contain the polyamide compound.

EFFECT: polyamide compound demonstrates the sufficient ability of absorbing oxygen in the absence of a contained metal, does not create any unpleasant smell and is characterised by very good transparency.
