The Bieler Press stocks several high quality calipered press packing materials, specifically those configured for hard, yet resilient, packing on letterpress flatbed cylinder presses. All materials supplied will fit 15- and 20-inch presses per cylinder size.
Currently stocked items include .002" and .003" Riegal, .004"/.005" LithPakII, and .006" Drum Head undersheets, as well as .007" PolyPak (tympan top sheet for 15") and .021" (15"), .017", .011" Kimlon (tympan bottom sheet). These are available in economical small lots. Materials provided are not scored or die cut for specific presses and sheet sizes are maximized for largest 15- and 20-inch presses, thus you will need to cut to fit using templates.
