    "Polymaker's wiki says its cardboard can still slip on AMS rollers, and it splits adapter materials by temperature. It names PolyLite PLA Pro for ambient use or a 45 °C (113 °F), 12-hour PLA dry, and PC or PETG for a 65 °C (149 °F), 12-hour dry."

Score 3 says Bambu sells PPA-CF on cardboard because it can be dried hotter than plastic spools. r/BambuLab 109ck01, score 2, says they rip one side off an Overture cardboard spool and slide it onto a reusable spool, and that Polymaker is also using cardboard. The other score 2 says some newer eSUN matte spools are cardboard, and to print rings or move the filament onto a Bambu spool.
