Transparent films
Ultrasonic sensors are often selected when optical contrast is low or the web is transparent.
Film, Foil & Flexible Webs
Web Guiding and Tension Control for Film Lines
Film and foil webs can stretch, wrinkle or lose edge definition. KRD helps match sensors, controllers and actuators to the material behavior.
Material Behavior
Film lines require careful sensor and tension selection
Low-tension handling
Closed-loop feedback helps protect thin films from stretching or wrinkles.
Compact guiding
Integrated EPC units can reduce installation time where machine space is limited.

Common film web guiding and tension control applications
Film, foil and flexible packaging machines often need web edge guiding before printing, coating, laminating, slitting, inspection or rewinding. A stable package combines the right web guide sensor, EPC controller, actuator and tension control loop for the material and machine layout.
Converting and slitting lines
Edge guide systems help keep film aligned before knives, inspection stations and rewind sections, reducing uneven rolls and edge waste.
Coating and laminating lines
Stable web tension control helps thin materials pass coating, drying and laminating zones without wrinkles, stretching or tracking drift.
Flexible packaging lines
Transparent film, printed film and laminated webs may require ultrasonic sensors, photoelectric sensors or line-guide modes depending on edge contrast.
Which sensor works best for transparent film?
For clear film and low-contrast web edges, an ultrasonic web guide sensor is usually the safest starting point because it detects the web edge without relying on printed contrast.
What should I provide for film line selection?
Send the material type, web width, line speed, tension range, correction location, available actuator space and photos of the machine section. These details help KRD match the web guiding and tension control components correctly.
