CN208148701U 一种低透明度防潮湿PET膜 有权

一种低透明度防潮湿PET膜
摘要：
本实用新型公开了一种低透明度防潮湿PET膜，包括依次设置的上层PET聚酯基层、非导电镀层和下层PET聚酯基层；所述上层PET聚酯基层的上表面设置有第一聚丙烯酰胺层，且所述第一聚丙烯酰胺层的上表面设置有聚氯乙烯层，所述聚氯乙烯层的上表面设置纳米氟聚合物粒子层；所述下层PET聚酯基层的下表面设置有第二聚丙烯酰胺层；且所述第二聚丙烯酰胺层的下表面设置有纳米氟聚合物粒子层。本实用新型中由于在上层PET聚酯基层的上表面设有聚氯乙烯层，使得PET膜上表面具有更高的耐热性、柔韧性和抗老化的特点，并且能够达到很低的透光率，使得光线基本不会穿入PET膜，设置的聚丙烯酰胺层，使得PET膜整体能有效阻隔氧气、水蒸气透过PET膜，能够延长PET膜的使用寿命。
摘要（英）：

The utility model discloses a low transparency moisture proofing PET membrane, including upper PET polyester base layer, non - conductive coating and the lower floor PET polyester base layer that setsgradually, the upper surface on upper strata PET polyester base layer is provided with a polyacrylamide layer, just the upper surface on a polyacrylamide layer is provided with polyvinyl chloride layer, polyvinyl chloride layer's upper surface sets up nanometer fluoropolymer particle layer, the lower surface on lower floor PET polyester base layer is provided with the 2nd polyacrylamide layer, just the lower surface on the 2nd polyacrylamide layer is provided with nanometer fluoropolymer particle layer. The utility model discloses in because upper surface on upper PET polyester base layer isequipped with polyvinyl chloride layer for the epimembranal surface of PET has the characteristics of higher heat resistance, pliability and ageing resistance, and can reach very low luminousness, makes light basically can not penetrate the PET membrane, the polyacrylamide layer of setting, make the PET membrane whole can effective separation oxygen, vapor sees through the PET membrane, can prolong the life of PET membrane.
