PROBLEM TO BE SOLVED: To provide a filtration bag for raw milk that is made of a raw material or a single material. SOLUTION: This filtration bag for raw milk is constituted only with nonwoven fabric made of the high temperature-melting core and low temperature-melting sheath conjugated filaments and the nonwoven fabrics are heat-sealed into a bag form. In a preferred embodiment, the high melting component is made of polyethylene terephthalate, while the low melting component is made of polyethylene. The nonwoven fabric preferably has partially thermocompression bonding areas. COPYRIGHT: (C)2006,JPO&NCIPI
