Four-layer co-extruded high-adhesion film production line

The next-generation, high-precision, four-layer co-extruded self-adhesive mold, jointly developed with Taiwan’s Hongtai, combines high adhesion, exceptional transparency, advanced technology, and energy efficiency, representing a new product in the field of high-adhesion protective films.

Three-layer co-extruded blown film production line

In‑die cooling significantly boosts production output and enhances transparency; a horizontal oscillating‑rotary draw‑down system replaces the die‑head rotation, completely eliminating issues such as material leakage, sealing difficulties, and maintenance challenges, while delivering excellent film flatness.

Five-layer co-extruded blown film production line

It is compatible with high-barrier materials such as EVOH and PA, and features EPS photoelectric tracking for web guidance, air‑cushion guide steel rollers, and a high‑precision die‑ring air‑blowing system, ensuring uniform thickness and high production efficiency to meet the demands of high‑barrier packaging films.

Seven-layer co-extruded blown film production line

A high-end, multi-layer co-extrusion platform; internal cooling within the IBC significantly enhances film transparency and intrinsic quality. Combined with high-precision diameter control and photoelectric web‑guiding, it is ideally suited for the large-scale production of high‑performance, high‑barrier functional films.

Remote Service System

The control system is equipped with a remote service module and a backend data-processing system. All system data are displayed in real time and stored on the system’s computer, enabling storage, traceability, export, and transmission to the backend. Furthermore, all parameters can be accessed via the backend data network.

Multi-component micro-weight automatic weighing and extrusion control system

The multi-component micro‑weight automatic weighing and extrusion control system comprises a vacuum feeding system, a material storage system, a weighing and batching system, a mixing and loss‑in‑weight weighing system, a central feeding system, and a host‑computer system, among others.

Single-component rice weighing and extrusion control system

The single‑component, micro‑weight automatic weighing and extrusion control system comprises a material‑suction system, a material‑storage system, a weighing system, and a host‑computer system. During operation, raw material is continuously fed from the weighing hopper to the screw in an automated manner. The host computer calculates real‑time production output by acquiring the weight‑loss signal from a high‑precision load cell mounted beneath the weighing hopper. Simultaneously, via communication with the screw‑drive unit, the host adjusts the extrusion rates of each stage of the screw to achieve precise control over both total output and layer‑ratio distribution. Additionally, by integrating signals such as traction speed, web width, and raw‑material density, the host computer regulates film thickness.

Airflow-based Automatic Air Ring Control System

The wind‑temperature‑type automatic air‑ring control system receives measurement parameters from the thin‑film thickness‑measurement system via communication at its input end, and connects to the air‑ring electrical unit through heavy‑duty connectors at its output end. It also incorporates upper‑rotation signals and parameters, traction signals and parameters, fan signals and parameters, and temperature signals and parameters. Based on these inputs, the industrial PC builds a model to dynamically control and adjust the heating increments and decrements in each zone, ensuring that the film‑thickness deviation remains below the setpoint.

Scanning Thin-Film Thickness Measurement System

X-rays are penetrating: the source emits rays that pass through the film being measured, causing attenuation, while the detector measures the attenuated radiation intensity. For a given material, the attenuation coefficient remains constant; as the film thickness increases, the detected radiation intensity decreases. Based on this principle, the current film thickness can be accurately determined, making this method suitable for measuring various transparent films, barrier films, and opaque colored films.

Mold air ring and IBC internal cooling control

Utilizing Taiwanese molds, its runner design, operating principle, and material‑feeding distribution demonstrably outperform the conventional bottom‑feed or outer‑side‑feed technologies currently employed in the industry.

Rotational traction system

Horizontal structure with ball‑bearing drive, unlike the earlier bearing‑based design; smoother operation and higher reliability.

Reel-up system

It can effectively address issues such as surface bubbles and wrinkles caused by viscous films.

Reel winder

It can effectively address issues such as surface bubbles and wrinkles caused by viscous films.

Electrical Control

The main electrical cabinet is heated using solid-state relays, and all inverters are housed in separate cabinets equipped with forced‑air cooling and dust‑proofing devices.

Traction-type rotary bubble internal cooling blown film production line (7 layers)

The horizontal reciprocating swing‑and‑rotate motion of the traction unit replaces the die head’s rotation, significantly simplifying the die head structure and eliminating issues such as material leakage, sealing difficulties, and maintenance challenges caused by rotational movement. It also addresses quality problems like uneven film roll diameters and inconsistent edge tension, ensuring excellent flatness of the finished film.

Extruder

The extruder barrel is made of advanced aluminum alloy, offering high thermal efficiency and a long service life; however, the extruder’s barrel employs air cooling to automatically regulate temperature.

Die head and air ring

The air ring serves to cool the film bubble extruded from the die and blown into shape, with air as the cooling medium. At the same time, the airflow provides some support to the film bubble. The air ring can significantly increase the production capacity of the extrusion‑blowing unit.
