TYPE CP22A cover tape is a transparent polyester film with
static dissipative properties on both sides and heat sealable over a wide range
of temperatures, thus making it immensely suitable for different materials of
carrier tape.
The adhesive system is specially developed for tight range in seal strength, as an addition to its stable seal strength.
