1500 mm High-Speed Polyethylene Film Blowing Machine

The 1500 mm High-Speed Polyethylene Film Blowing Machine converts HDPE and LDPE resin into tubular polyethylene film through extrusion, air cooling, haul-off, and winding. It is suitable for producing film for shopping bags, T-shirt bags, garbage bags, and general packaging. The listed configuration provides a maximum extrusion capacity of 140 kg/h, with film dimensions and auxiliary equipment selected according to the required production specifications.

Wide Film Format
The listed configuration supports film widths of 1000–1400 mm and thicknesses of 0.01–0.40 mm. The selected operating range should match the finished product and downstream converting equipment.

Defined Extrusion Configuration
An 80 mm screw with a 30:1 L/D ratio forms the basis of the listed extrusion system. Screw speed, processing temperature, and resin properties determine the operating conditions required for the target output.

Adjustable Haul-Off
The haul-off speed ranges from 10–100 m/min. Speed settings are coordinated with extrusion output, cooling conditions, and film thickness to maintain the required film dimensions.

Coordinated Film Forming
The die head, air ring, haul-off, and winding unit work together throughout production. Matching these components to the resin and film specifications helps establish suitable processing conditions.

Selectable Auxiliary Equipment
Automatic loading, screen changing, corona treatment, and winding options can be considered according to material handling, surface treatment, and roll collection requirements.

Shopping Bags: Produces polyethylene film for shopping and carrier bags. Film width and thickness should match the bag dimensions, cutting layout, and sealing process.

T-Shirt Bags: Supports film production for T-shirt bag converting lines. The required roll width and thickness depend on bag size and the operating range of the downstream equipment.

Garbage Bags: Suitable for film used in household and commercial garbage bags. Resin grade and film thickness should be selected according to the finished bag dimensions and performance requirements.

General Packaging: Processes polyethylene film for wrapping, protective packaging, and other flexible packaging applications. Material selection should reflect the intended use and required film properties.

Extrusion Unit
The 80 mm screw and 30:1 L/D ratio define the listed extrusion arrangement. Resin grade, temperature settings, and screw speed influence melting behavior and output. Final settings should be established for the selected material.

Die Head
The listed configuration specifies a 140 mm die for HDPE and a 250 mm die for LDPE. Die selection should be confirmed against the resin, target film dimensions, and required thickness distribution.

Air Cooling
The 1000 mm air ring and 7.5 kW cooling fan form part of the cooling arrangement. Airflow and extrusion output must be matched to the film bubble and production conditions.

Haul-Off System
The 1500 mm haul-off roller supports the film-forming arrangement. Haul-off speed is adjusted in coordination with extrusion output and cooling to achieve the target film dimensions.

Double Winder: A double-winding arrangement can be selected when separate roll collection or a specific winding workflow is required. Roll width and winding specifications should be confirmed during configuration.

Automatic Roll Changing: Automatic roll changing can be considered for production lines requiring a defined roll-change process. The configuration depends on roll dimensions and the required operating sequence.

Corona Treatment: Corona treatment can increase the surface energy of polyethylene film for printing or lamination. Treatment requirements should be matched to the selected ink, adhesive, and downstream process.

Automatic Loading: An automatic loader transfers resin into the extrusion hopper. Its capacity and arrangement should match material consumption and the production workflow.

Screen Changer: A screen changer supports melt filtration before the resin enters the die. Selection depends on resin cleanliness, filtration requirements, and the extrusion configuration.

Confirm Output Requirements: The listed maximum extrusion capacity is 140 kg/h. Actual output varies with resin grade, film width, thickness, and processing conditions. Establish the expected operating output for the intended product before finalizing the machine configuration.

Match Film Dimensions: Confirm the target film width, thickness range, and roll dimensions. These values determine the appropriate die arrangement, haul-off settings, and winding requirements.

Check Installation Conditions: Confirm available floor space, installation height, electrical supply, voltage, frequency, and phase. Allow room for roll removal, routine maintenance, and material handling.

Review Line Compatibility: Check the required roll dimensions and film specifications against the downstream bag-making or converting equipment. This helps align film production with the next processing stage.

Machine configuration can be tailored to confirmed production requirements and factory conditions.
