1 1 - 4 0 / R e v 1 5
TYPES OF SEAL OPENABILITY/FAILURE
Interfacial Peel Seal
• Composition of seal layer
• Temperature, Dwell, Pres-
sure
• Sealing die configuration
• Thickness of seal layer
• Contamination of seal
layer (dust)
• All of the above
• All of the above
• Stiffness & deadfold
SERVO-DRIVEN JAW ACTUATOR
The servo-driven jaw actuator is designed for the Ultima SV. The
servo-driven jaw is a bolt-in option to the pneumatic actuators on 12in.
and wider machines, enabling integrated programmable jaw motion.

or lamination
• Hot tensile strength of
film
• Same as interfacial fail-
