Product Description

Single-screw double-head Film Blowing machine

Designed for high efficiency, this machine features a robust single extruder that simultaneously supplies molten plastic to two independent blowing heads. This unique configuration allows for the production of two separate film rolls at the same time, effectively doubling your production capacity compared to a conventional single-head machine.

Corona Treatment

Dryer

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.

The primary purpose of the dryer (or dehumidifying dryer) in a blown film extrusion process is to remove moisture from the plastic resin pellets before they are melted and extruded.

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.
