An efficient and safe device designed to perform the difficult task of opening tightly fitting Shrink Wrap plastic packaging material and security tape around a product or product case, particularly that used for the distribution of CD-ROM'S, DVD'S, videogames, and videotapes. The device quickly cuts a clean slit opening in the Shrink Wrap and security tape along the inserted edge of the packaged product. The cutting element of the device can be in the form of a wire or blade, and function via heating, mechanical cutting action, and/or ultrasonic vibration. A multiple-capacity alignment channel guides various shaped products into proper cutting position. Sensors may activate the cutting/slitting action, with adequate heat, vibration, and/or mechanical cutting being applied for a time period sufficiently long, or until sufficient temperature is reached, to cut through the Shrink Wrap material and security tape without damaging the underlying product or product case.
