Abstract

The present invention discloses a multilayer film with high antibacterial resistance and a preparation method thereof. The key points of the technical scheme are that the multilayer film with high antibacterial resistance consists of three layers, namely an antibacterial layer, a barrier layer and a support layer, wherein the antibacterial layer is located at the outermost layer of the film and adopts a material containing antibacterial components, the barrier layer is located below the antibacterial layer, and the support layer is located below the barrier layer; the present invention solves the problem that the antibacterial effect of traditional antibacterial films decays over time by adopting self-repairing materials and sustained-release technology; the sustained-release agent is designed to control the release rate of the antibacterial components so that it maintains a stable antibacterial effect during long-term use, and by selecting a high-strength support layer material and adopting an optimized processing technology, the tensile strength, tear resistance and wear resistance of the film are significantly improved, and the peeling or damage of the antibacterial layer caused by the influence of the external environment (such as friction, ultraviolet radiation, etc.) is avoided, thereby improving the long-term stability and service life of the film, and having strong market potential.
