Abstract

The invention discloses a covering film for medicinal PTP (press through packaging). The covering film is prepared from paper, a polyester film layer and an aluminum foil through composition, wherein an ink layer and a gloss oil layer are arranged on the outer surface of the paper; a first binder layer is arranged between the paper and the polyester film layer; a second binder layer is arranged between the polyester film layer and the aluminum foil; a hot-sealing layer is arranged on the other surface of the aluminum foil. A preparation method of the covering film comprises steps as follows: (1), printing; (2), the first time of composition; (3), the first time of curing; (4), glue applying; (5), the second time of composition; (6) the second time of curing; (7), slitting; (8), packaging. The paper, the polyester film and the aluminum foil are composited, accordingly, the strength of the covering film is improved, the covering film can be prevented from being broken by children, and the safety is improved; with the adoption of the aluminum foil, vapor and oxygen can be further blocked; the preparation method is simple and easy to implement; the pulling strength index of the covering film prepared with the method reaches 55.3-106.9 N/15 mm, and the hot-sealing strength of the binder layers reaches 13.5-16.2 N/15 mm.
