FILM PACKAGING DEVICE |
摘要 |
The disclosure provides a film packaging device, which introduces a drying layer having no influence on the transmittance and stability of a substrate into a packaging structure of a film barrier layer. The drying layer is in a filled groove structure, has a strong hygroscopic effect and has no influence on light transmission at the same time, and can avoid the damage and influence on the stability of the barrier layer and a functional layer of the device caused by hygroscopic expansion. The introduced drying layer may increase the water and oxygen permeation resistance effect of the barrier layer by 1 or 2 orders of magnitude, thereby having an important action on the improvement of the service life of a flexible device, and the drying layer may also be used in an organic/inorganic multilayer alternating flexible packaging film structure, thereby reducing the number of organic/inorganic alternating layers on the basis of guaranteeing a water and oxygen barrier effect. |
