The 1700 mm High-Speed Polyethylene Film Blowing Machine converts polyethylene resin into continuous tubular film through extrusion, air cooling, haul-off and winding. It is suitable for producing film for shopping bags, garbage bags and general packaging. The extrusion system, die head, cooling unit and winding assembly can be configured to match the required film dimensions, resin grade and production capacity. Custom equipment configurations are available according to specific production requirements.
Key Advantages
Production Capacity: The extrusion system can be specified according to the target output, film thickness and resin grade. Rated capacity should be confirmed against the intended operating conditions.
Film Width Selection: The 1700 mm nominal size provides a basis for equipment selection. The usable lay-flat width is determined by the die configuration and required film dimensions.
Process Control: Temperature regulation, cooling airflow and haul-off speed support consistent film formation. Operating parameters should be matched to the selected resin and film specification.
Configuration Flexibility: The extrusion unit, cooling assembly, traction system and winding arrangement can be selected according to the intended product and downstream converting process.

Film Applications
Shopping Bags: Produces polyethylene film for shopping bags and carrier bags. Film dimensions and material properties should match the required bag size and converting process.
Garbage Bags: Suitable for producing film for household and commercial waste bags. Resin grade and film thickness should be selected according to the required finished-film properties.
General Packaging Film: Processes polyethylene resin into film for everyday packaging. Film width, thickness and roll specifications should match the intended packaging process.
Industrial Packaging: Can be configured for suitable industrial packaging applications after the required film dimensions, material grade and production conditions are established.
Material and Film Requirements
Resin Compatibility: HDPE, LDPE and LLDPE are commonly used in blown-film production. Resin suitability depends on the machine configuration, material grade and required film properties.
Film Thickness: Specify the target thickness range and allowable variation before confirming the extrusion configuration. Resin characteristics and operating conditions affect the achievable production range.
Finished Film Width: Confirm the required lay-flat width, roll dimensions and downstream equipment requirements. The nominal machine size should be checked against the actual usable film width.
Configuration and Customization
Extrusion Unit: Screw dimensions, drive power and temperature-control settings should match the selected resin and target output.
Die and Cooling Assembly: Die dimensions and cooling capacity should correspond to the required film width, thickness and production rate.
Haul-Off and Winding: Traction components and winding arrangements should accommodate the required film format and finished roll dimensions.
Electrical and Auxiliary Systems: Power supply, control configuration, material feeding and auxiliary equipment can be specified according to the production requirements. The final equipment list should distinguish standard components from optional items.
Production and Quality Considerations
Output Verification: Confirm the rated extrusion output and the conditions under which it applies. Film width, thickness and resin grade should be included in production planning.
Thickness Consistency: Extrusion stability, die condition, cooling airflow and haul-off control influence film thickness consistency. Required tolerances should be defined in the technical specification.
Roll Quality: Winding tension, roll width and roll diameter affect handling and downstream processing. Confirm the required roll dimensions and winding arrangement before production.
Installation and Order Planning
Factory Layout: Allow sufficient space for the extrusion unit, cooling assembly, haul-off system and winding station. Final space requirements should follow the confirmed machine dimensions.
Electrical Supply: Confirm local voltage, frequency, phase and total installed power before order confirmation. The agreed electrical configuration should be documented.
Documentation and Accessories: Confirm the equipment list, operating documentation, included accessories and recommended spare parts before finalizing the order.
Shipping Preparation: Verify machine dimensions, shipping weight, packaging method and delivery scope to coordinate transportation and site preparation.
Frequently Asked Questions
Q: What materials can this machine process?
A: HDPE, LDPE and LLDPE are common blown-film materials. Suitable resin grades should be confirmed against the selected extrusion configuration.
Q: What film width can it produce?
A: The machine has a nominal 1700 mm designation. The usable lay-flat width should be confirmed from the die specification and technical data.
Q: What is the maximum extrusion output?
A: The rated output depends on the equipment configuration, resin grade, film width and thickness. The applicable capacity should be confirmed in the technical specification.
Q: Can the machine be customized?
A: Yes. The extrusion unit, die, cooling system, haul-off, winding and auxiliary equipment can be configured according to the required film specifications and factory conditions.
Q: What information is needed for a quotation?
A: Provide the target film width and thickness, resin grades, required output, intended application, local power supply and preferred winding arrangement. These details help establish the equipment configuration and quotation scope.
