An easy-opening insulation package for containing a stack of resilient insulation batts, such as but not limited to glass fiber insulation batts, is formed from a sheet material. The sheet material completely encircles the batts and has a stress riser that extends longitudinally with respect to the batts for the length of the batts. Preferably, the sheet material has at least one tear line, such as a perforated line, extending generally perpendicular to and crossing the stress riser for creating an opening in the package through the rupture of the sheet material by. hand along the perforated line and for permitting the stress riser to be separated by hand from the opening created along the perforated line to gain access to the batts within the package. Preferably, the ends of the package are closed and the perforated line completely encircles the package to permit the package to be separated into two sections by rupturing the perforated line along its entire length.
