having a gauge thickness of about 90 gauge, a balanced shrink
ratio in x and y orientations to provide a uniform and

of about 140EF.
To cure these deficiencies, the examiner turns to
Ashmore, Rosenblatt and Watanabe. Ashmore discloses a heat
shrinkable food packaging film which is biaxially stretched or
