Abstract
A bag for packaging products includes a generally parallelepiped-shaped body of composite sheet material having a rectangular closure zone formed at one end. A closure line extends across the closure zone between the upper and lower sides of the closure zone and a through cutout is formed in the closure zone at the closure line to facilitate opening of the bag. Preferably, the cutout is defined by first and second edges which are generally perpendicular to one another. The first edge is substantially perpendicular to the upper edge of the closure zone and the second edge adjoins the lower end of the first edge and extends substantially parallel to the upper and lower edges of the closure zone. The upper end of the first edge also extends above the upper edge of the closure zone.
