PROBLEM TO BE SOLVED: To provide a packaging material for hydrostatic pressure press having pinhole resistance to be able to bear the hydrostatic pressure press irrespective of its thinness, and to provide a hydrostatic pressure press method using the packaging material. SOLUTION: A film, in which a biaxially oriented linear low-density polyethylene layer is laminated on a film having a nylon layer and/or a polyethylene terephthalate layer, is used preferably as the packaging material for hydrostatic pressure press. The film has a bag shape with the biaxially oriented linear low-density polyethylene layer arranged inside. An object to be pressure bond-molded is put in the bag, the bag is sealed, and the hydrostatic pressure press is applied to the bag. COPYRIGHT: (C)2010,JPO&INPIT
