    Abstract: A biaxially stretched polyester film for forming a container, characterized by being formed of a polyester substantially consisting of an ethylene terephthalate unit and an ethylene naphthalate unit, the refractive index in the direction of thickness of the film being 1.5 or greater. This film is not only excellent in the formability during formation into cans or the like, but has excellent properties in taste property, particularly, the taste property after the retorting, and may be suitably used for containers produced by forming process and, particularly, for metallic cans.

    Abstract: According to the present invention there is provided a polyester composition comprising an aromatic polyester having copolymerized therein a compound containing at least one sulfonic acid group or sulfonic acid metal salt group, and crosslinked polymer particles, preferably crosslinked polymer particles coated with a water-soluble polymer. The particles are incorporated in a slurried state into the polymer. There is also provided a laminate film containing the polymer with the particles thus incorporated therein. The polyester composition is superior in uniform dispersibility of the particles, re-agglomeratin does not occur in melt-storage for a long time, and films formed using the polyester composition are superior in traveling performance and abrasion resistance.

    Abstract: The present invention provides a hollow fiber membrane module that can effectively resolve the accumulation of suspended solids within the membrane module, lower running costs, and also operate stably. The present invention relates to a hollow fiber membrane molecule provided with: a cylindrical case having a first end and a second end in the direction of height; a plurality of hollow fiber membranes accommodated within the cylindrical case; and a first potting part accommodated within the cylindrical case and attaching the plurality of hollow fiber membranes together such that the end parts of the plurality of hollow membrane fibers at a first end side of the cylindrical case are open. The hollow fiber membranes are porous hollow fiber membranes having a breaking strength of 23 MPa, and the hollow membrane module has a membrane area per unit volume of 800 - 3700 m
