PROBLEM TO BE SOLVED: To obtain a barrier type laminated packaging material and a paper vessel for liquid which are prevented from rotting or changing of quality of a content due to the penetration of gas and light beams, while the lamination is separated easily when the same are dipped into aqueous solution for re-pulp treatment after being used. SOLUTION: The barrier type laminated packaging material is provided with a first resin layer, a paper layer, a second resin layer, a barrier layer and a third resin layer sequentially from the outermost surface of a package. In this case, the barrier layer is an aqueous polymerized compound film provided with a diamond type carbon film at least on one side of the same.
