A method for manufacturing a container having a fracturable opening arrangement, the container including a shell portion formed of a sheet of crystallisable polymer material, the shell portion including a fracturable area within which a fracture can be initiated and propagated when stress is applied to the fracturable area; the method including; forming the sheet within a forming mould to produce a shell portion, and selectively applying heat to the fracturable area of the shell portion to thereby increase crystallisation of the polymer material within the fracturable area. |
