Newlife's plain magnetic sheets are permanent magnetic material with one side magnetized and the other side non-magnetized. It can be laminated with PVC, PP, paper and etc. The magnetized side is for working with magnetic receptive material, such as iron board. The minimum thickness is only 0.2mm ( 0.008'') and the maximum width is up to 1.52M(60''). We have different magnetic material with different magnetic property and strength, both standard energy magnets and high energy magnets.
