Trilaminar co-extrusion thermal contraction resin film, manufacturing method and application method thereof

The invention discloses a three-layer coextrusion heat shrinkage resin film, a production method and an application method. The-three layer coextrusion heat shrinkage resin film is produced by taking PE(LDPE, HPPE, LLDPE, mPE), EVA, PP, PA and EVOH resins as the main materials which are matched with a functional master batch and adopting a production method of one-step huffing. The largest transverse and longitudinal shrinking rates of the product can reach 60 percent and 85 percent; the largest shrinking force of the product can reach 2.0N/cm. The shrinking rate and the shrinking force of the product can be controlled and adjusted by controlling various technical parameters to lead a package to be firm and endurable. The packaged objects are pertinently led to reach the anti-rust, anti static, illumination-resistance, anti-aging, anti-puncturing, anti-low-temperature, anti-isolation, anti-bacteria and anti-degradation effects and the like by adjusting the material composition and mixture ratio of each layer. The three-layer coextrusion heat shrinkage resin film is used for replacing the traditional paper box wrappage to reduce the packaging cost. The mechanical properties are good, the pertinence is strong, the materials are saved; when the three-layer coextrusion heat shrinkage resin film is used, the shrinking temperature is low, the power is saved and the packaging cost is saved, thus effectively reducing the production cost and having extremely high application value.

Essential oil of tobaccos as well as preparation method and application thereof to cigarettes

The invention relates to the essential oil of tobaccos as well as a preparation method and application thereof to cigarettes. The essential oil of the tobaccos is prepared by the following method of: taking discarded/defective tobacco wastes, extracting by an organic solvent, taking the crude extract of the essential oil, introducing water vapor, condensing and separating oil and water so as to obtain the essential oil of the tobaccos. By adding the essential oil of the tobaccos, which is disclosed by the invention and is used as a flavoring agent, into the tobacco shreds of cigarettes, the self fragrance of the tobaccos can be increased, the quality of the fragrance of the cigarettes is enhanced, the excitation and the miscellaneous gas of the tobaccos are reduced, and smoke is softened. The essential oil of the tobaccos as well as the preparation method and the application thereof to the cigarettes have the advantages that the advantage of higher extracting yield of a solvent extracting method and the characteristic of refinement of a water-vapor distillation extracting method are combined, the yield of the essential oil of the tobaccos is obviously higher than that of a traditional water-vapor distillation method, and extracting equipment and a solvent are simple and convenient and are easy to obtain; and moreover, no solvent residue exists in a final product of the essential oil of the tobaccos, and the safety of the product is high.
