A package has a flexible top wall (3) joined in its periphery (6) to flexible side walls (4, 5) to form an enclosure, the top wall (3) being formed with a line of weakness (7) which is adapted to be torn to create an opening, the tear being confined between the peripheral join (6), The side walls (4, 5) may have transverse seals (1, 2), and top and bottom walls (3) folded inwards as gussets, and the line of weakness (7) with a thumb on each side of the line of weakness (7) with a thumb on each side to press downwards and create a tear along the line of weakness. Preferably, the upper edges of the side walls (4, 5) are sealed to the adjoining edges of the top wall (3) to form a peripheral upstanding rim (6). |
