Abstract
A pharmaceutical packaging composite film includes a heat sealing layer, an aluminum foil layer, and an impact resistant layer. The heat sealing layer contains residues derived from at least one of 1,4-butanediol, isophthalic acid, isoprene glycol, and isopropanol, and thus has a melting point between 130° C. and 180° C. The aluminum foil layer is disposed on the heat sealing layer. The impact resistant layer is disposed on the aluminum foil layer.
