Applications

Surface protection material used during transport and processing of stainless plates and aluminum plates. The tape can stay on during the laser cutting process.
Also applies to the bending process.

Precautions during laser process

For tasks in which protective film for laser processing etc. is burned, gas will be generated as a result of the burning, so be sure to equip with exhaust facilities, wear protective masks for organic gases, etc. When working in a poorly-ventilated area, headaches or dizziness may occur.
Peeling film, underside burrs, etc. differ according to processing conditions. Please thoroughly consider processing conditions before use.
