PURPOSE:To obtain a paper container having good barrier properties by preventing the lowering of barrier properties due to the crack of a part subjected to hill form folding or trough form folding by a folding rule by providing a barrier layer having inorg. oxide vapordeposited on both surfaces thereof to both surfaces of the plastic film in laminated constitution having paper as a base material. CONSTITUTION:As one example of a laminated material 1, a polyethylene film layer 2, a paper layer 3, a polyethylene resin layer 4, a polyethylene resin layer 5, a barrier layer 6 and a polyethylene film layer 7 are laminated successively from the outside of a container. The barrier layer 6 is formed by providing a silicon oxide layer on both surfaces of a polyester film 8 by vapor deposition and vapor deposition layers 9 are formed on both surfaces of the polyester film 8. Therefore, even when one vapor deposition surface of the barrier layer 6 is stretched and folded by folding at a time when end edge folding-back treatment as a packing material is performed or a paper container is assembled, the other vapor deposition surface is folded in a non-stretched state and the crack-free vapor deposition surface can be always obtained on the single surface of the barrier layer.
