Abstract
An easy access tear-open paperboard package and method of making same are provided including a pair of corrugated paperboard sheets, each having an interior surface flood coated with a cohesive material which sheets are then joined together in surrounding relation to an article such as a book contained therebetween. A strip of polyolefin tape extends across the interior surface of at least one of the corrugated paperboard sheets to provide a non-bonding area. A pair of spaced parallel perforations extend through paperboard sheet and the tape to form a tear strip which is narrower in width than the tape to provide access to the interior compartment.
