The invention relates to a melt-blown film, a multilayer film and a preparation method thereof. The technical scheme of the melt-blown film is as follows: the raw material is melted and sprayed to form a film, the raw material includes basic raw materials, and the selection of basic raw materials has the following characteristics Substances: molten at 30‑500℃, and soluble in water at room temperature. The basic raw materials include sugars and/or sugar derivatives and/or high molecular compounds. A multi-layer melt-blown film of the present invention is prepared by superimposing melt-blown films of melt-blown films. The multi-layer functional film of the present invention includes a meltblown film and an active layer, and the active layer is soluble in water or can be uniformly dispersed. The meltblown film or multi-layer film product of the present invention has low cost, good efficacy, few side effects, environmental protection and greenness, energy reduction and consumption reduction, and wide application range. |
