    摘要: A press-through package obtained by placing objects to be packed, in the accommodating pockets formed by vacuum forming or the like of a sheet made of a thermoplastic norbornene type resin, particularly preferably a hydrogenated product of ring-opening polymerization product of a dicyclopentadiene type monomer, and then closing the openings of pockets of the sheet with another sheet such as metal foil to pack the objects to be packed, which package makes the packed objects clearly visible in the pocket portions, prevents the deterioration of the packed objects by moisture bacause of its excellent water vapor barrier properties, and is good in production efficiency.
