PEK離型紙是將PE粒子通過(guò)流延機(jī)涂覆在紙張表面。由于表面附著PE層,相對(duì)來(lái)說(shuō)具有更好的防潮性。同時(shí)由于PE粒子的特性,PEK具有更高的撕裂度和柔韌性。 PEK is manufactured by coating silicone polymer on poly-coated side of base paper. The extruded PE-layer is primarily protecting the paper against moisture and is enhancing the dimensional stability of a liner.
