Optional Accessories

Corona Treatment

Double Winder

In the blown film machine, Corona Treatment is a key surface modification process, mainly used to enhance the surface energy of plastic films, thereby improving their printability, coatability and adhesiveness.

Double Winder is an efficient post-winding equipment, mainly used to achieve continuous winding of films, thereby significantly improving production efficiency and reducing manual intervention.

Meter Counter With Alarm

Rotary Die Head

Meter Counter With Alarm is a core quality control device that integrates precise measurement and intelligent early warning. Its function goes far  beyond basic counting-it actively intercepts production anomalies through real-time monitoring and threshold alarm to reduce waste loss.

The Rotary Die Head mainly used for production plastic films with special patterns, textures or composite structures. Its core function is to achieve dynamic adjustment or functional design of the film's properties through rotational motion.
