Laser Pocket Opener is a high-tech packaging machine. Its working principle is to use laser beams to heat plastic packaging bags to make them fuse quickly, so as to achieve the effect of opening bags. Compared with the traditional mechanical bag opening method, the laser bag opening machine has the advantages of fast bag opening speed, high precision and high efficiency. However, some people are more concerned about the radiation problem of the laser bag opener. Let me introduce it in detail below.

First of all, the radiation of the laser bag opening machine mainly includes two aspects: optical radiation and thermal radiation. The optical radiation of the laser bag opening machine mainly refers to the light generated by the laser beam, which mainly affects the eyes. However, when using the laser bag opener, the operator needs to wear protective glasses, so as to effectively avoid the damage of the laser to the eyes.
Secondly,The thermal radiation of the Laser Pocket Opener mainly refers to the heat generated when the laser heats the pocket opening. This thermal radiation may cause certain damage to human skin, but the laser bag opening machine is usually equipped with a protective cover, and the operator only needs to operate in the protective cover to effectively avoid the hazards of thermal radiation.
In addition to the above two types of radiation, the laser bag opener also has a potential safety hazard, that is, the laser beam may cause cancer on objects.
