Twin-Head Shopping Bag Film Production Machine

The Twin-Head Shopping Bag Film Production Machine uses one screw extruder and two die heads to produce two polyethylene film streams simultaneously. It is suitable for narrow-width film used in shopping bags, T-shirt bags and other PE bag applications. The production line integrates extrusion, film blowing, air cooling, haul-off and winding. Resin grade, film width, thickness and required output determine the appropriate configuration. Custom options are available to match production specifications and downstream bag-making requirements.

Two Film Outputs: The twin-head arrangement produces two film streams through one extrusion system. It suits narrow-width film production where two rolls can be processed within the same production cycle.

Flexible Film Specifications: Film width and thickness can be matched to the intended bag dimensions and converting process. Die selection, cooling conditions and winding settings should be confirmed against the target film specifications.

Integrated Production Layout: Extrusion, cooling, haul-off and winding are arranged within one production line. This allows the main process sections to be coordinated around the available installation space and production workflow.

Configurable Equipment: Optional systems can be selected according to material feeding, surface treatment, winding and process control requirements. The final equipment list should identify the selected configuration and included accessories.
 

Shopping Bags: Suitable for polyethylene film used in shopping bags, subject to the required film dimensions and material properties.

T-Shirt Bags: Supports film production for die-cut handle bags. Film thickness, width and mechanical properties should match the intended bag dimensions and converting process.

Flat Bags: Suitable for flat-bag film applications within the confirmed operating range of the selected configuration.

Other PE Bags: Additional applications can be assessed according to resin grade, film specifications, winding format and downstream processing requirements.

Film Dimensions: Specify the target layflat width and thickness for each film stream. These values determine the required die configuration and influence cooling, haul-off and winding settings.

Output Requirements: State the required output in kilograms per hour and clarify whether the target applies to both film streams combined. Production capacity should be evaluated against the intended resin, film dimensions and operating conditions.

Roll Specifications: Confirm the required roll width, maximum diameter and winding format. These details help establish compatibility with material storage, handling and downstream bag-making equipment.

Extrusion and Die System: The screw and die configuration can be assessed according to resin grade, film dimensions and required output. Material compatibility and the operating range should be confirmed before finalizing the specification.

Optional Equipment: Available options may include a rotary die head, double winder, automatic roll changer, corona treater, screen changer, automatic material loader and gravimetric dosing system. Availability depends on the selected machine design.

Electrical and Layout Requirements: Confirm the available voltage, phase, frequency and installation space. Equipment layout and auxiliary systems can be reviewed against the factory's operating conditions.
 

Bag-Making Requirements: Provide the intended bag type, finished dimensions and bag-making machine specifications. Film width, thickness and roll dimensions should match the downstream feeding requirements.

Surface Treatment: Corona treatment can be considered when the film requires improved surface wettability for printing or other surface-dependent processes. The required treatment level depends on the intended application.

Production Line Coordination: Review film output, winding format and downstream processing speed together. This helps establish a suitable configuration from film extrusion through bag conversion.

Material and Product Data: Confirm the resin grade, target film width, thickness range and intended bag type. Blended or recycled materials require compatibility assessment before the extrusion configuration is approved.

Capacity and Utilities: Confirm the required hourly output, power supply and installation conditions. The production target should be evaluated against the intended film specifications.

Supply Scope: The quotation should list the main machine, included accessories, selected options, spare parts, technical documentation and agreed commissioning arrangements. Delivery terms and technical support scope should also be confirmed.
