Gas permeable contact lenses are rigid lenses made of durable plastic that transmits oxygen.
Functional gas-permeable Packaging material is a 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. In fact, gas permeable contacts transmit more oxygen to the eye than do traditional soft contact lenses (although some silicone hydrogel soft lenses are comparable to GP lenses in oxygen transmission). Rigid gas porous lenses are rigid get hold of lenses cleared of oxygen-permeable polymers. Initially educated fashionable the deep 1970s, and through the 1980s and 1990s, they were an improvement over prior 'hard' lenses that curtailed oxygen transmission to the eyeball.
These lenses also are called GP lenses, rigid gas permeable lenses, RGP lenses and oxygen permeable lenses. Hybrid lenses are also available, which combine some of the advantages of both rigid and soft lenses.
Desiccant packaging real, oil&water insubordinate packaging substantial and other packaging stuffs with air travel permeability are imported from Japan and external respiration sued from the special engineering science of our company, and then sold to the drying agent and oxygen absorber fabrications. Rigid lenses are able to replace the natural shape of the cornea with a new refracting surface.

yes it is a very good material for packaging........ although i have heard of various material like Aluminium film, paper, cardboard, Barrier film, and much more.........
