Body-paper-free environment-friendly thermosensitive label and preparation method thereof

The invention relates to a body-paper-free environment-friendly thermosensitive label and a preparation method thereof. The body-paper-free environment-friendly thermosensitive label comprises a thermosensitive composite layer and a gluing layer, wherein the thermosensitive composite layer comprises a silicone oil layer, thermosensitive paper and a polyethylene layer; the silicone oil layer coversa thermosensitive surface of the thermosensitive paper; the polyethylene layer covers a non-thermosensitive surface of the thermosensitive paper; the silicone oil layer is UV solvent-free silicon orwater-based silicone oil; and the polyethylene layer is composed of low-density polyethylene and high-density polyethylene. The body-paper-free environment-friendly thermosensitive label is rolled toform a product, the cost is saved, and the product is light and thin. 本发明涉及一种无底纸环保型热敏标签及其制备方法，无底纸环保型热敏标签包括热敏复合层和涂胶层，热敏复合层包括硅油层、热敏纸、聚乙烯层，硅油层覆盖在热敏纸的热敏面上聚乙烯层覆盖在热敏纸的非热敏面上，硅油层为UV无溶剂硅或水性硅油，聚乙烯层为低密度聚乙烯和高密度聚乙烯组成，将无底纸环保型热敏标签收卷形成产品，节约成本，
