The HM 900 security sealers are designed as a compact sealing machine producing a unique embossed code in the seal enhancing the security of the contents. Increased security by being able to lock the sealing bar down, so the machine becomes tamperproof as well. They are used by Banks for packing money during storage and transport and by Police Forces around the UK for "tamper-proof" protection of drugs evidence, exhibits, property, finger prints etc. This machine is simple to maintain with consumable spares being easy to fit and available from Hulme Martin.
