Tubular package |
摘要 |
A flexible package is defined by an inner package layer and a surrounding outer package layer. The inner and outer layers define a tubular body and opposing end portions. A first region of weakness is provided within the outer package layer and is spaced from one end of the package. The region of weakness within the outer packaging layer forms an opening mechanism for the outer layer to expose the inner packaging layer. A second region of weakness is provided within the inner package layer and is spaced from the end of the inner package. The second region of weakness positioned offset from the first region of weakness, to permit the two opening mechanism to be separately activated. |
