Abstract
An easy-opening, liquid-tight package has an interior space for storage. The package includes a front wall, a rear wall opposing the front wall, a pair of opposing side walls, a bottom wall and a top wall opposing the bottom wall. A seal wall is contiguous with the top wall and extends from a juncture of the top wall and the seal wall. The seal wall has an edge that is opposite the juncture. The seal wall is sealed to the front wall at an exterior surface of the front wall. At least one line of weakness is formed in the top wall, extending from the seal wall at the edge into the top wall. The line of weakness defines a cover portion of the top wall. The cover portion is formed from a portion of the seal wall and a portion of the top wall. When the top wall and seal wall are separated along the line of weakness, the cover portion is separable from the package to define an open area for accessing the interior storage space of the package. A blank for the package is also disclosed.
