Abstract
A scored package is described. The first panel of the package comprises a multilayer film with an exterior layer having a nonlinear first score Sine and an interior layer having a linear second score line. The first score line and the second score fine are positioned non-parallel in a plane of the package such that the first score line intersects the second score line to form an opening in the package at the second score line when the exterior layer and the interior layer are separated. Separation of the exterior layer and the interior layer also forms an adhesive-free pour spout in the separated exterior layer. Various embodiments of various package configurations, score line configurations, multilayer film structures and methods of manufacturing are also described.
