Abstract

The invention discloses a production process of a packaging composite film, comprising the following steps: (A) configuring a hyperbranched cationic mussel imitating polymer into an aqueous binder solution, the hyperbranched cationic mussel imitating polymer comprising polyphenolic hydroxyl di Benzophenone enamide monomer, cationic monomer and photoresponsive monomer; (B) preparing graphene oxide solution; (C) immersing the polymer film in the aqueous binder solution, taking it out and drying it, and immersing the polymer film in (D) soak the polymer film prepared in the step (C) in the aqueous binder solution, take out and soak the polymer film in the graphene oxide solution after drying; (E) repeat steps ( D); (F) putting the polymer film prepared in the step (E) into an aqueous reducing agent solution, heating to reflux and condensing to obtain a packaging composite film. The invention saves the corona step, not only reduces the process cost, but also simplifies the process steps.

Description

technical field [0001] The invention relates to the field of packaging materials, in particular to a production process of a packaging composite film. Background technique [0002] As the main packaging material of pharmaceuticals, polymer film packaging materials have become more and more important in daily life. However, due to the influence of the plastic film production process and its own physical and chemical characteristics, it is difficult for the barrier properties of plastics to oxygen, water vapor, liquid substances and other low molecular weight substances to meet the requirements of most pharmaceutical packaging. The penetration of small molecular gases such as oxygen and water vapor into packaging materials will lead to oxidative deterioration of the active ingredients in the drug, which in turn will cause the reproduction of microorganisms and other phenomena. The direct consequence is that the shelf life of the drug is greatly shortened. Therefore, it is of ...
