ABSTRACT:
A structure for use in making an easy open package comprises a thermoplastic sheet material. The sheet material has a strip of reflective metal on one surface. Over the metal strip on the opposite surface of the sheet material is a score line. The score line may be formed by a laser. The metal strip reflects the laser and provides a score line of more uniform depth and also provides barrier properties in the area of the score line.
