An oxygen barrier layer comprising microfibrillated dialdehyde cellulose

The present invention relates to a method for manufacturing at least one fibrous barrier layer wherein the method comprises the steps of: providing a first suspension comprising microfibrillated dialdehyde cellulose， mixing the first suspension with at least one inorganic pigment to form a mixture， applying said mixture to a substrate to form a wet fibrous web and drying said wet web on said substrate to form a fibrous barrier layer.It also relates to a fibrous barrier layer comprising microfibrillated dialdehyde cellulose and at least one inorganic pigment.

本发明涉及一种制备至少一层纤维阻隔层的方法，该方法包括如下步骤：提供包含微纤化二醛纤维素（microfibrillated dialdehyde cellulose）的第一悬浮液，将该第一悬浮液与至少一种无机颜料（inorganic pigment）混合以形成混合物，将所述混合物涂布至基材上以形成湿纤维网，并在所述基材上干燥该湿纤维网以得到纤维阻隔层。本发明还涉及一种包含微纤化二醛纤维素与至少一种无机颜料的纤维阻隔层。
