Flexible Magnets
In either strip, roll or sheet form, flexible ferrite magnetic material fromMMG has become the choice for printing industry for promotionalmaterials, vehicle signage and toys.
Flexible ferrite can be supplied with and without a PVC or adhesivebacking. The PVC backing can be printed on directly therebyeliminating the need for laminating a printable material on the magnetprior to printing. Both our FLEX6 and FLEX11 grades are normallymagnetised on one face for maximum holding power, but can besupplied axially magnetised to special order.
Standard Product Size Range and Backing Options:
Thickness: 0.4 mm to 3.0 mm0.015 in to 0.120 in
Width: 12.5 mm to 610.0 mm0.5 in to 24.0 in
Length: 80 mm to 3000 m3 in to 1000 ft
Backing: Plain, AdhesivePVC
Steel, Zinc
Custom die cutting and PVC colours other than white are also availableupon request.
