Unimagnet provides front edge solution of wide flexible magnet printing. Maximum width can reach 1.0 meter of magnetic rolls, 0.4mm and 0.7mm thickness available, length can be adjusted by customers.
Flexible magnetic rolls and magnetic sheets are made by strontium or barium magnetic ferrite powder mixed with additive by special proportion, pass through mixer and a pair roller to preliminary laminate, finally after agglomerated process will produce final products. Magnetic rolls and magnetic sheets are mainly applied for advertising, decoration and artworks.
For protecting surface and increase shininess of flexible magnetic rolls and sheets, UV coating is adopted. Particularly, for exceptional outdoor weatherability and anti-stick when stacked on, Vinyl(PVC) and Pressure Sensitive Adhesive(PSA) backing is adopted as well ,and various color free choosen by customers.
Flexible Magnetic rolls and magnetic sheets have good machinability can easily be bent, folded, and punched without reducing magnetic energy. Magnetic rolls can be cut into magnetic sheets,Unimagnet provides A4 and A3 size magnetic sheets specially for direct printing.
