Abstract
A plastic film punching apparatus is improved to make a waste removed reliably. In the apparatus, a plastic film is sandwiched between and punched by male and female blades. The female blade has opposite surfaces which are first and second surfaces. The plastic film generates a waste which is pushed by the male blade to protrude from the second surface. A vacuum source and an opening cooperate with each other to suck air through the opening and generate airflow within the tubular cover, the waste being removed by the airflow.
