Transparent moisture-proof film

Uses: organic electroluminescent sheet, solar thin film battery, electronic devices, pharmaceutical packaging, etc., to protect the seal against moisture penetration.
Significance: Improve the life of the device in the humid environment 1-5 times.
Principle: The surface of the PET film is prepared with a special barrier molecular permeable layer.
Usage: Through the household card film hot pressing laminator, hot press paste sealing. Or hot pressed film sealing by hot pressing film sealing machine.
Specifications: coil width 1.2m, length 250m / volume, light transmittance of 95% or more, material special PET
Film: thickness is about 0.125mm, and the edge width is recommended to be more than 2mm.
Storage: Store at room temperature for 23 years and seal for more than 10 years. Store in normal environment for more than 5 years (the adhesive strength may drop); use an electronic drying cabinet for 48 hours before use.
