<P>PROBLEM TO BE SOLVED: To provide a roving package with a wound roving body hard to collapse. <P>SOLUTION: The roving package 1 includes the wound roving body 2 and a packaging material 3. The wound roving body 2 is formed of a roving wound cylindrically. The packaging material 3 surrounds the outer periphery of the wound roving body 2. The packaging material 3 has a packaging material body 4 and a thermoplastic resin layer 5. The thermoplastic resin layer 5 is provided on the inner surface of the packaging material body 4. In differential scanning calorimetry, the thermoplastic resin layer 5 has one or more heat absorption peaks in a temperature range of 50-80°C and has one or more heat absorption peaks in a temperature range of 100-120°C. <P>COPYRIGHT: (C)2013,JPO&INPIT |
