The Dual-Line T-Shirt Bag Making Machine converts polyethylene film rolls into T-shirt shopping bags through automatic feeding, heat sealing, cutting and handle punching. Its two-lane production arrangement supports the simultaneous processing of two bag lanes within one machine. It is suitable for supermarket shopping bags, retail carry bags and general-purpose packaging. Configuration can be tailored to the required bag dimensions, film specifications, production capacity and factory conditions.
Key Advantages
Two-Lane Production
Two bag lanes operate within one machine, allowing parallel production according to the selected configuration. Actual output depends on bag dimensions, film thickness, sealing time and operating speed.
Consistent Bag Formation
Controlled film feeding and coordinated sealing and cutting help maintain consistent bag dimensions. Film tension and sealing settings should be matched to the material and finished-bag specifications.
Integrated Handle Punching
The handle-punching unit forms the characteristic T-shirt bag handle. Punch dimensions and positioning should be confirmed against the required bag design.
Configurable Automation
Servo control, automatic counting and finished-bag handling can be assessed according to the machine configuration. The selected functions should match the required production process and packing method.

Bag Types and Applications
Supermarket Shopping Bags
Produce T-shirt-style bags for supermarkets, grocery stores and everyday retail packaging. Bag width, length, handle dimensions and film thickness should match the required finished product.
Retail Carry Bags
Support routine production of plastic carry bags for retail distribution. Different bag sizes can be assessed according to the machine's confirmed processing range.
Printed Shopping Bags
Printed-film production can be specified when compatible registration control is available. Print-mark detection and positioning requirements should be confirmed before configuration.
Packaging Production Lines
The dual-line arrangement suits operations requiring two bag lanes in one machine. Expected output should be evaluated against the planned product mix and packing workflow.
Film Material Compatibility
HDPE Film
HDPE is commonly used for lightweight shopping bags. Film thickness, material grade and sealing behavior should be checked against the machine's processing range.
LDPE and LLDPE Film
LDPE and LLDPE can be evaluated for bag applications requiring different material properties. Confirm film specifications and sealing conditions before selecting the configuration.
Biodegradable Film
Biodegradable film can be considered when its composition and processing requirements are compatible with the machine. Material suitability should be confirmed through technical review and production testing where necessary.
Production Control and Output
Line Speed: Confirm the rated speed of each lane and the combined output under specified operating conditions. Bag length, film thickness and sealing requirements affect actual production rates.
Bag Length Control: Specify the target bag length and dimensional tolerance. The feeding and control system should match the required product dimensions.
Print Registration: For printed film, confirm print-mark detection, registration method and positioning tolerance before production.
Counting and Collection: Automatic counting, stacking and finished-bag collection can be specified according to batch quantities and downstream packing requirements.
Customization Options
Bag Dimensions: Configuration can be assessed against the required bag width, length, handle shape and sealing dimensions.
Film Specifications: Film type, thickness, roll width and roll diameter can be reviewed to establish suitable feeding and sealing arrangements.
Production Capacity: The two-lane configuration and available automation options can be evaluated against target output, product mix and planned operating hours.
Electrical and Auxiliary Equipment: Power supply, compressed air and auxiliary equipment requirements can be confirmed for the installation site. Customization is subject to technical feasibility.
Configuration and Purchasing Checklist
Finished-Bag Specifications: Provide bag samples or drawings showing width, length, handle dimensions and sealing details. These measurements establish the basis for equipment selection.
Film Data: Confirm film type, thickness, roll dimensions and printing requirements. Accurate material data helps determine the appropriate processing configuration.
Output Requirements: State the target output per minute or per shift, expected bag sizes and planned operating hours. Specify whether the output target refers to each lane or both lanes combined.
Factory Conditions: Confirm floor space, installation access, electrical supply and compressed air requirements. Include space for film-roll handling, machine operation and finished-bag collection.
Installation and Technical Support
Pre-Installation Review: Check machine dimensions, utility requirements and factory layout before shipment to prepare the installation area.
Commissioning: Define test materials, target bag dimensions, operating conditions and acceptance criteria before commissioning.
Operator Training: Training can cover operating procedures, parameter adjustment, routine maintenance and basic troubleshooting according to the supplied configuration.
Technical Documentation: Confirm the availability of operating instructions, electrical diagrams, maintenance guidance and spare-parts information in the delivery agreement.
Frequently Asked Questions
Q: What bags can this machine produce?
A: It is intended for T-shirt-style plastic shopping bags made from compatible film. Final bag dimensions and handle specifications depend on the selected configuration.
Q: How is dual-line output calculated?
A: Combined output depends on the operating speed of both lanes under the same production conditions. Actual output should be confirmed through the rated specifications and agreed test conditions.
Q: Which film materials can it process?
A: HDPE, LDPE, LLDPE and compatible biodegradable films can be evaluated according to the machine configuration and material specifications.
Q: Can the machine be customized?
A: Yes. Bag dimensions, film requirements, production targets and compatible automation options can be reviewed for a suitable configuration.
Q: What information is required for a quotation?
A: Provide bag dimensions, film type and thickness, target output, printing requirements, destination power supply and preferred automation options. Drawings or bag samples help clarify technical requirements.
