The Integrated Bag Making and Packing Line connects plastic bag production, counting, stacking and finished-bag packaging in one coordinated process. It is intended for T-shirt bags and vest bags made from compatible polyethylene films. Bag dimensions, film thickness, required pack quantity and packaging format determine the appropriate configuration. Customized solutions can be discussed according to production targets, factory layout and electrical requirements.
Key Advantages
Connected Production: Bag forming and packaging operate in sequence, reducing manual handling between production stages and simplifying finished-bag transfer.
Accurate Pack Counting: Counting and grouping settings can be matched to the required number of bags per pack, supporting consistent batch preparation.
Coordinated Output: Bag-making speed and packaging cycle time are assessed together to establish a suitable production configuration.
Packaging Flexibility: Packaging film, pack dimensions and sealing requirements can be selected according to the finished product and downstream handling process.
Integrated Production Process
Film Feeding and Bag Forming
The film unwinding system feeds plastic film into the bag-making section. Heat sealing and cutting form bags to the specified dimensions, with handle punching configured according to the selected bag style.
Counting and Stacking
Finished bags are collected, counted and arranged into groups. The counting method and transfer mechanism depend on bag dimensions and the required pack quantity.
Automatic Packaging
Grouped bags enter the packaging unit for wrapping and sealing. Packaging material, finished-pack dimensions and sealing settings are selected according to the packaging specification.
Finished-Pack Discharge
Completed packs are transferred to the discharge area for inspection, carton packing or storage. The equipment layout should allow convenient access for material replacement and finished-product handling.
Bag Types and Applications
T-Shirt and Vest Bags: Suitable configurations support vest-style shopping bags used in supermarkets, retail stores and general merchandise packaging.
Polyethylene Film Bags: The bag-making section supports compatible HDPE, LDPE and LLDPE films. Film thickness and material properties must be matched to the selected configuration.
Retail Packaging Production: The line suits operations requiring counted bag bundles and organized finished packs for storage, distribution or shipment.

Production Capacity and Output Planning
Bag-Making Output
The listed bag-making speed is 200–300 bags per minute. Actual production output depends on bag dimensions, film properties, machine settings and operating conditions.
Packaging Throughput
Packaging capacity is measured in packs per minute. Required bags per pack and the packaging cycle determine the capacity needed from the packaging unit.
Line Capacity Matching
Production planning should consider target daily output, operating hours, product changeovers and packaging requirements. The final rated output should be agreed for the complete line rather than inferred from bag-making speed alone.
Customization Options
Bag Specifications
Bag width, length, film thickness, material and handle design can be reviewed to determine the suitable forming configuration.
Packaging Format
Packaging film, pack dimensions, bags per pack, counting method and sealing requirements can be specified according to the intended finished product.
Electrical and Layout Requirements
Voltage, frequency, available floor space and compressed-air supply should be confirmed before the equipment arrangement is finalized. Configuration options can be discussed according to the production process and operating requirements.
Installation and Project Preparation
Factory Layout
Allow sufficient space for film loading, operator access, packaging material replacement, finished-pack collection and routine maintenance. Layout planning should cover the complete connected line.
Utility Requirements
Confirm electrical capacity and compressed-air requirements using the final equipment specification. Total installed power should account for the bag-making unit, packaging unit and auxiliary equipment.
Commissioning
Confirm bag dimensions, film material, pack quantity and packaging format before trial production. Installation guidance, commissioning and operator training can be agreed as part of the project scope.
Frequently Asked Questions
Q: What bag types can the line produce?
A: The primary applications are T-shirt bags and vest bags. Other bag styles require confirmation of the forming, sealing, cutting and packaging configuration.
Q: Which film materials are supported?
A: The existing bag-making range supports HDPE, LDPE and LLDPE films. Compatibility should be checked against the selected material specification and complete-line configuration.
Q: Can the number of bags per pack be adjusted?
A: Pack quantity can be specified according to the required finished product. The available settings depend on the selected counting and packaging system.
Q: How is production capacity calculated?
A: Capacity depends on bag-making speed, bags per pack and packaging cycle time. The rated output of the complete line should be confirmed for the selected configuration.
Q: Can the line be customized?
A: Yes. Bag dimensions, film specifications, packaging format, production targets, electrical requirements and installation layout can be reviewed when preparing the equipment configuration.
