How to make small hole on shiitake bags after filling?

Since the raw materials for Shiitake mushroom cultivation are relatively coarse, after filling, the plastic bags have high porosity. During sterilization, the gaps between the materials trap cold air, which expands when heated, easily causing the bags to swell. Therefore, before entering the sterilization pot, it is typically necessary to punch small holes with a diameter of 3 to 5 millimeters and apply breathable tape automatically as an air vent.
