Where to get Functional gas-permeable Packaging material?

Rigid gas permeable lenses are rigid contact lenses made of oxygen-permeable polymers. Initially developed in the late 1970s, and through the 1980s and 1990s, they were an improvement over prior 'hard' lenses that restricted oxygen transmission to the eye.
Rigid gas permeable are able to replace the natural shape of the cornea with a new refracting surface. This means that a regular (spherical) rigid contact lens can provide good level of vision in people who have astigmatism or distorted corneal shapes as with keratoconus. However, they require a period of adaptation before full comfort is achieved.
Desiccant packaging material, oil&water resistant packaging material and other packaging materials with air permeability are imported from Japan and ventilation processed by the special technology of our company, and then sold to the desiccant and oxygen absorber manufactures.
