Abstract

The invention belongs to the technical field of packaging materials, and relates to a packaging material for an electronic cigarette and a preparation method thereof, the packaging material for the electronic cigarette is composed of a polytrifluorochloroethylene layer, a polyurethane adhesive layer and a polyvinyl chloride layer which are stacked; wherein an adhesive adopted by the polyurethane adhesive layer is a three-component polyurethane adhesive. The preparation method at least comprises the following steps: compounding the polytrifluorochloroethylene layer and the polyvinyl chloride layer through a three-component polyurethane adhesive by adopting a dry compounding process, and drying and curing to obtain the packaging material for the electronic cigarette. The packaging material for the electronic cigarette can effectively block permeation of external water vapor and oxygen, meanwhile, the storage and transportation safety of the electronic cigarette in a low-temperature environment is improved, and the specific fragrance of the electronic cigarette is effectively kept.
