strip secured to the film which allows for controllably tearing
an opening through the film for accessing an article or articles
within the enclosed region. The tearable tape strip is defined
by opposing, longitudinal edges and a central section that is
tearable relative to the longitudinal edges. According to
appellants, “[c]onventional tear strips cannot tear a ‘clean’
opening” through films having the recited puncture-propagation

resistance are polyethylene, linear low-density polyethylene,
low-density polyethylene, and blends of polyethylene.
