PURPOSE:To improve the strength of a sealed part when a packaging material is made into a tube shape, and at the same time, improve the bag tear resistant strength, and increase the filling efficiency and yield, when the packaging material is used for a filling package of a ham or sausage. CONSTITUTION:Corona discharge treatment is applied on an unwoven fabric sheet which consists of a synthetic long fiber with a sheath and core structure, for which the melting point of a core component polymer is higher than the melting point of a sheath component polymer by 30 deg.C or more, to give viscose coating property. |
