Multimax seals are self-adhesive, whereas Polycarbonate seals are wire based. The purpose of both is to seal the meter such that the meter cannot be opened without tampering these seals. The Multimax seal has a visual security feature like a hologram for easy identification of the genuine and untampered seal. In case of any tampering with the Multimax seals, there are telltale signs to show that the meter is tampered with.
