PURPOSE:To provide a layered structure which comprises a polyolefin, a second polymer compound noncompatible with the polyolefin, and a modified polyolefin and has a liquid-and gas-barrier effect, and a process for manufacturing the same. CONSTITUTION:This layered structure comprises a polyolefin, a second polymer compound noncompatible with the polyolefin, and a modified polyolefin, and the polyolefins form a continuous matrix phase, the second polymer compound being in the form of a thin band is present in the matrix, phase where each band lay in a row without substantial gap and forms a wide layer parallel to the surface. The structure has good liquid-and gas-barrier properties. |
