The 350mic Pop Up Blockout Banner IJPUBB3501 is a heavy weight, matt coated banner made from 100% polyester film for ultimate rigidity. Designed for use with pop-up display systems, it has an opaque blockout layer sandwiched between two bright white outer layers. The 350mic Pop Up Blockout Banner coating allows for heavier ink weights and the white back gives a clean professional look compared to the grey back of alternative products. For use with dye and pigment inkjet printers.
