The tape is not perforated

Non-perforated tape 25 mm for polycarbonate 4 mm, 6 mm, 8 mm.
Non-perforated tape 38 mm for polycarbonate 10 mm, 16 mm.

The tapes are intended to close the ends of the sheets, ensuring tightness. Perforated tape provides sufficient ventilation of honeycomb polycarbonate tunnels, solid tape does not let anything inside at all. But it does not allow condensate to escape. Therefore, it would be ideal to use both types of tape - on the one hand, solid - on the other, perforated.
