Description
Technical Field
The utility model relates to the technical field of films, especially, relate to a polypropylene film with super hydrophobic function.
Background
The alkene film is a commonly used packaging bag material at present, and has the advantages of high transparency, good thickness uniformity, low-temperature heat sealing, low cost and the like. At present, the packaging materials used for products such as food, medicine and the like mainly adopt polypropylene films, and polyethylene films have different performance requirements according to use occasions, for example, the packaging films applied to more special product packaging have antistatic effect, and the common base vinyl resin is easy to accumulate static electricity, so that the packaging materials can not be used in the occasions with the antistatic requirement. In addition, common polypropylene films do not have the surface hydrophobic property, in order to obtain the surface hydrophobic property, people usually select films made of other materials, so that the application field of the polypropylene films is limited, and therefore a polypropylene film with a super-hydrophobic function is provided to solve the problems.
SUMMERY OF THE UTILITY MODEL
The utility model aims at solving the problem that the existing polypropylene film in the prior art has single performance and limits the application range of the existing polypropylene film, and providing the polypropylene film with the super-hydrophobic function.
In order to achieve the above purpose, the utility model adopts the following technical scheme:
the utility model provides a polypropylene film with super hydrophobic function, includes the polypropylene layer, the polypropylene layer includes the polypropylene sandwich layer and sets up polypropylene corona layer and the polypropylene heat-seal functional layer in polypropylene sandwich layer both sides, one side on polypropylene layer is equipped with antibiotic layer, antibiotic layer is kept away from one side on polypropylene layer is equipped with the ultraviolet resistance layer, the opposite side on polypropylene layer is equipped with the active agent layer, one side that active agent layer and ultraviolet resistance layer kept away from mutually all is equipped with the hydrophobic layer.
Preferably, the ultraviolet-resistant layer, the antibacterial layer, the polypropylene layer, the active agent layer and the hydrophobic layer are fixedly connected together through a multilayer tape casting extrusion process, wherein the thicknesses of the ultraviolet-resistant layer, the antibacterial layer, the active agent layer and the hydrophobic layer are less than 20% of the thickness of the polypropylene layer, and the thickness of the polypropylene layer is 20-35 μm.
Preferably, the hydrophobic layer is a transparent super-hydrophobic material layer structure.
Preferably, the active agent layer is a hard resin acid monoglyceride structure.
