Richmond Technology engineers developed the CAV-40 product in response to the market demand for a high barrier clear film with excellent cleanliness characteristics. The proprietary outer layer delivers extraordinary moisture vapor barrier properties while the inner sealant layer offers outstanding cleanliness characteristics. None of the harmful process aids (i.e. slip, anti-block, etc.) used in traditional polyethylene sealant layers are present.

CAV-40 is the choice for clean transparent moisture barrier protection of sensitive product during transport and/or storage.
