When a buffered tissue is not acceptable, our non-buffered Renaissance Tissue is the ideal liner choice. This is the lighter-weight version of the Photographic Storage Papers, but made of a heavier-bond than wrapping tissue. For use with albumen, cyanotype, dye transfer, color prints (chromogenic) and textiles. The 2.5mil. (45g/m2) weight provides a strong, crisp tissue with good transparency. We watermark each sheet to identify the presence or absence of the buffering agent. All papers pass P.A.T.100/pkg
