The 1300 mm High-Speed Polyethylene Film Blowing Machine converts polyethylene resin into continuous tubular film through precision extrusion, air cooling, haul-off, and winding processes. It is engineered for producing continuous lay-flat films utilized in shopping bags, garbage bags, agricultural covers, and general flexible packaging. The extrusion system, die head, cooling unit, and winding arrangement are coordinated to match the required film width, thickness, resin grade, and target output. Customized configurations are available to align with specific factory layouts and processing requirements.
Key Advantages
Application-Based Configuration: The extrusion system, die head, and winding arrangement can be matched to the intended film specifications, establishing a stable processing foundation.
Controlled Film Forming: Coordinated extrusion temperature, precision cooling airflow, and stable haul-off speed maintain bubble stability and uniform film thickness during continuous production.
Integrated Production Process: Extrusion, cooling, traction, and winding work synchronously to convert raw resin into high-integrity finished film rolls suitable for downstream converting.
Flexible Equipment Options: Selected components and auxiliary devices can be configured according to available floor space, utility inputs, and targeted film applications.
Applications
Plastic Shopping Bags: Produces high-integrity polyethylene film optimized for high-speed bag-making conversion lines, meeting precise width and thickness tolerances.
Garbage Bags: Suitable for manufacturing durable film rolls for household and commercial refuse sacks, supporting high-load strength and reliable sealing properties.
General Packaging Film: Supports continuous production of protective wrapping and standard packaging films within the established operational gauge range.
Industrial Packaging Bags: Can be configured for specialized industrial film and heavy-duty bag applications after confirming required mechanical strength and resin grades.

Production Configuration
Extrusion Unit: Features an optimized barrier screw geometry and high-torque drive system designed to ensure stable polymer melting, homogenous plasticization, and steady output.
Die Head: Precision-machined alloy steel die with uniform flow channel design, ensuring even melt distribution and stable tubular bubble formation across the target width range.
Cooling and Haul-Off: Equipped with a high-efficiency dual-lip air ring and adjustable blower system, coupled with a steady-speed traction roller unit to control bubble cooling and gauge uniformity.
Winding System: Incorporates tension-controlled surface or center winding mechanisms to ensure tightly wound, wrinkle-free finished rolls with uniform edge alignment.
Film Quality and Output
Thickness Consistency: Precision temperature zoning and optimized air cooling minimize gauge variation, delivering stable micrometer tolerances across the film web.
Effective Film Width: The usable film width is calibrated based on die gap selection and lay-off frame dimensions, keeping production clear of edge waste.
Production Capacity: Rated hourly output is balanced against resin melt flow index (MFI), target thickness, and ambient shop conditions to guarantee predictable batch yields.
Finished Roll Specifications: Winding tension and roll dimensions are tailored to match subsequent printing, slitting, or bag-making conversion equipment requirements.
