    • PURPOSE: Provided are a recyclable adhesive tape for packaging and its preparation method comprising an adhesive mixed with an acryl polymer and a water proof and alkalescence dissociable polypropylene glycol alkyl phenylether-based plasticizer, being coated on the front side of graft paper which is coated with release layer of water soluble silicone resin to let re-pulping possible. CONSTITUTION: The tape is composed of coated the re-pulping possible release layer on the back side of graft paper which is mixed with 10-15% PVA aqueous solution and water soluble silicone resin in a weight ratio of 1:1 and coated one time in order to have the dried thickness of 3-5 micron; and the adhesive coated on the front side which is mixed with an acryl polymer and the water proof and polypropylene glycol alkyl phenylether-based alkalescence alkali dissociable plasticizer to be maintained 10-25% solid contents in order to have the dried thickness of 30-40 micron. Drying is conducted at 95-105deg.C for 60-100 seconds in each process.
    • 目的:提供一种用于包装的可回收胶带及其制备方法,其包括与丙烯酸聚合物和防水和碱解离的聚丙二醇烷基苯基醚类增塑剂混合的粘合剂,涂覆在接枝纸的正面上,涂覆有 释放水溶性有机硅树脂层,使再制浆成为可能。 构成:胶带由接枝纸背面的再制浆可能的脱模层组成,与10-15%的PVA水溶液和水溶性有机硅树脂以1:1的重量比混合并涂覆一次 以使干燥厚度为3-5微米; 涂布在与丙烯酸聚合物混合的前侧上的粘合剂和防水聚丙二醇烷基苯基醚类碱性碱解离增塑剂保持10-25%固含量,以使干燥厚度为30-40 微米。 干燥在95-105℃进行,每次加工60-100秒。
