TYPE CP31 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.
Recommended Sealing Parameters:
Sealing Temperature: 150°C – 180°C
(Depends on machine set-up)
