<p>This flexible packaging (10) comprises a flexible film (14) wrapped around a product (12) to be packaged, the film (14) defining a closed space (24) containing the product (12), the film (14) having a higher tensile strength over most of its surface and a lower tensile strength over a well located partial weakening area (26), the higher tensile strength being sufficient for preventing a manual tearing and the lower tensile strength being adapted for allowing a manual tearing of the film (14). Its partial weakening area (26) has, along all directions, a dimension which is lower than 25 % of the corresponding dimension of the packaging, and the film (14) comprises a visible marking (28) locating the position of the partial weakening area (26).</p> |
