Angle board machines are primarily used in the packaging and logistics industries to produce edge protectors that prevent pallet collapse and strap damage. Functional requirements include automatic gluing, paper tension control, and hydraulic pressing. If your clients require specialized shapes, look for machines capable of producing U-profile, V-profile, or wrap-around (flexible) corner protectors. The ability to integrate an online printing module for branding or batch coding is also a high-value functional requirement for B2B buyers.
