▎ 摘　　要

NOVELTY - Vacuum bag film with heating function includes conductive heating layer and vacuum film layer. The conductive heating layer includes 10-40 pts. wt. carbon-based conductive material, 10-40 pts. wt. binder, and 20-50 pts. wt. solvent. USE - Vacuum bag film used in packaging (claimed). ADVANTAGE - The vacuum bag film helps in reducing energy loss and production costs; and has important research value. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is included for a method for preparing vacuum bag film, which involves: (A) mixing carbon-based conductive materials, binders, solvents, and additives to obtain carbon-based conductive inks; and (B) coating on vacuum film, and curing to obtain vacuum bag film.
