Loptima Film Tech

High Barrier Film



It is a high-performance barrier film product that uses advanced vacuum coating technology to evaporate a transparent silicon oxide barrier layer on a PET substrate. The composite film prepared by compounding with other materials has excellent water vapor and oxygen barrier properties and can be applied to quantum dots. membrane and other fields.
