LDPE 北欧化工 Borealis PE CC7209 铝箔涂料 包装 食品包装 层压板 建筑材料 涂层应用

CC7209是专为密封刘离应用而设计的挤压涂层等级。当密封在自身和PE上时，它能产生光滑和容易的剥离。(C7209还可以很好地粘附到各种基底上，尤其是铝。本发明的方法是将其与比例为1:1的标准低密度聚乙(LDPE)进行混合处理，如使用标准低密度聚乙(LDPE)。材料必须预先干燥，但仍有轻微的堵塞过滤器和填料结块的风险。(C7209含有30%的细分散填料。(C7209包含细分散填料，但不含其他添加剂。CC7209 is anextrusion coatino qrade especially designed forseal-pee applcations. t gves smooth and easy peel when sealedagainst tself and PE. CC7209 provides alsogood adhesion to varioussubstrates, particularly to aluminium. The rorommendation is to mixit with standard lDPE with the ratio 11 in this mixure proresinoikestandard LDPE can be applied.The material must be pre-dried butthere can be stil a slight risk for flter blocking and fileragglomeration.
