An aseptic liquid packaging container (100) is disclosed. The liquid packaging container made from a cup stock paperboard and may be a laminate structure (200b) configured to form the container. It can be a plurality of layers configured to form the laminate structure (200b) wherein at least one layer of the plurality of layers is a cup stock paperboard layer (204b).

The present invention relates to a press-heating gas grafting hydrophobization apparatus, and a hot water-resistant paper and an oil-absorbing paper manufactured using the press-heating gas grafting hydrophobization apparatus. In the press-heating gas grafting hydrophobization apparatus according to the present invention, since a non-air-permeable dryer belt is provided surrounding and pressing a drying roller to prevent dissipation from a base material of a fatty acid chloride vaporized by the drying roller, the press-heating gas grafting hydrophobization apparatus has an advantage of improving efficiency of a gas grafting reaction. Therefore, by using the press-heating gas grafting hydrophobization apparatus according to the present invention, the reaction amount of fatty acid chloride per unit area can be remarkably improved.

The present invention relates generally to the field of multi-layer packaging material. In particular, the present invention relates to a multi-layer metallized paper-based packaging material comprising a paper layer, a pre metallization coating layer, a metallized layer, and at least one post metallization coating layer. The present invention further relates to the use of the multi-layer metallized paper-based packaging material in accordance with the present invention to package food and to a food package manufactured from the multi-layer metallized paper-based packaging material. In one embodiment of the present invention the multi-layer metallized paper-based packaging material can be recycled with other paper packaging materials.
