The bubble is cooled internally, resulting in a significant increase in production output and enhanced film transparency. The internal cooling system is advanced and reliable, with minimal deviation in the bubble‑fold path.

Unit Performance Characteristics

1. Internal cooling of the bubble significantly increases production output and enhances film transparency; the internal cooling system is advanced and reliable. The membrane vesicle folding deviation is small.

2. The traction unit employs a horizontal oscillating rotary mechanism, ensuring smooth rotation and stepless speed regulation.

3. Replaces the die head’s rotation, simplifying its structure and completely resolving issues such as material leakage, sealing difficulties, and maintenance challenges that arise from die‑head rotation.

4. Overcomes quality issues such as uneven film roll diameter and loose edges, ensuring the film… Good flatness.

5. EPS photoelectric tracking and correction system, with automatic deviation correction and guidance for neat winding.

6. Rotation of air-cushion-guided steel rollers and new-type flat-draw film leveling rollers Guidance: the film is neat and smooth.

7. High-precision molds and a wind-ring cooling system ensure uniform film thickness. Uniformity and high production efficiency.

8. Advanced and reliable electrical operation system.

Applicable resins: LDPE, LLDPE, HDPE , EVA, etc.
