摘要： The present invention relates to the use use of a high-density paper substrate (35a) made from cellulose fibres, as a gas-barrier material in a laminated packaging material (30) for packaging of oxygen sensitive products, and further to coated such high-density paper substrates (35) for increased gas barrier properties. The invention further relates to laminated packaging materials (30) comprising the high-density paper substrates or coated high-density paper substrates, and to packaging containers comprising the laminated packaging material, for packaging of oxygen-sensitive products.

摘要： The present invention relates to the use use of a paper substrate (10a, 10b) made from cellulose fibres, for a gas-barrier material in a laminated packaging material (40a) for packaging of oxygen sensitive products, and further to coated such paper substrates (30a) for increased gas barrier properties. The invention further relates to laminated packaging materials (40a) comprising the paper substrates or barrier coated paper substrates, and to packaging containers comprising the laminated packaging material, for packaging of oxygen-sensitive products, such as food products.
