BC-55/65/85 LDPE Blown Film Line
The LDPE blown film line is specialized equipment engineered for the production of plastic tubular films featuring integrated male and female profiles (grip seals). The process begins with raw polyethylene granules being fed into the screw and barrel assembly. Through a combination of external heating and internal friction, the material is melted and filtered to remove impurities. The molten resin is then extruded through a precision mold, cooled, and inflated into a film bubble before being wound into rolls. This grip seal film machine is the fundamental technology for creating the raw materials used in the self-sealing bag industry.

- Precision Frequency Control
Utilizing advanced inverters, the self-sealing film line offers accurate control over the extrusion speed, allowing for stable production even during high-speed operations.
- Integrated Closure Extrusion
This ziplock film extrusion line is equipped with specialized molds that extrude the interlocking zipper profiles simultaneously with the film body, ensuring a perfect match and high seal integrity.
- Stable Production Workflow
The PE film blowing machine is composed of nine core modules—including the motor, precision screw and barrel, die head, frequency inverter, V-board, and winding unit—all synchronized to ensure consistent film thickness and profile quality.
