What are the permitted frequencies for plastic sealer machines?

High frequency sealer machines are used in industry to join thermoplastic materials. This process uses electromagnetic waves that generate heat in the processed materials. To avoid interference with other equipment, the frequencies used by the sealer machines are precisely defined by international regulations.

 Standard frequencies used in sealer machines

The standard frequency used in plastic HF sealer machines is 27.12 MHz. This value belongs to what is known as the ISM (Industrial, Scientific, Medical) band, which is intended for industrial, scientific and medical equipment. The fixed frequency ensures that the sealing process does not interfere with communication on other radio frequencies. The sealer machines are included in the offer of the Zemat Technology Group.

 Reasons for choosing certain bands

The frequency in the ISM band, 27.12 MHz, was selected due to its low susceptibility to interference and efficiency in processing plastics. These waves are strong enough to generate heat in polar materials such as PVC or TPU, but at the same time they work on a wide transmission band that does not affect the operation of other equipment.

 Frequency regulations

International regulations specify the permitted frequency bands that high frequency sealer machines may use. In Europe, according to ETSI (European Telecommunications Standards Institute) and ITU (International Telecommunication Union) regulations, the designated ISM bands are the only permitted ranges for industrial equipment. This ensures that the sealer machines are used safely and in accordance with technical standards. Zemat Technology Group offers sealer machines.
