3w 5w UV laser marking food packaging bag, effectivelyanti-counterfeit
355nm UV laser marking on food packagingdoes not carbonize and scorch
UV laser marking date on food packaging canmake us enjoy at ease
The RFH S9 series 355 ultravioletsolid-state laser, built by professors and doctoral-level teams at home andabroad for 13 years, has no carbonization, scorching, and deformation duringthe marking and writing process of food packaging.
RFH UV laser has three outstandingcharacteristics: fast speed, high precision and high stability. This type oflaser etching technology can play an important role in the identification ofauthenticity of signs.
The 355nm ultraviolet laser has a smallfocus spot and a very small processing heat-affected zone. There is almost nodamage caused by heat, so it is called a cold light source. Because of the verysmall heat-affected area of the UV laser, it will not appear thermal effect,and the problem of deformation or scorching of processed food packagingmaterials is avoided.
