The Computer-Controlled Cold-Cut Bag Making Machine converts HDPE and LDPE film rolls into plastic bags through automatic feeding, heat sealing and cold cutting. It supports flat bags and selected shopping bag formats, with additional tooling available for compatible bag designs. Computerized length control helps maintain consistent bag dimensions, while optional photoelectric tracking supports printed film processing. Machine configuration can be customized according to bag size, film specifications, production targets and factory requirements.
Key Advantages
Accurate Length Setting
Set the required bag length through the computer control system. Consistent length settings support repeat production and simplify adjustments when switching between confirmed bag specifications.
Controlled Heat Sealing
Adjustable temperature settings help match the sealing process to the film material and thickness. Correct process settings support uniform seals and consistent bag formation.
Printed Film Registration
Optional photoelectric tracking detects printed registration marks and coordinates cutting positions with the printed layout. Compatibility depends on mark contrast, print position and film movement.
Flexible Production Setup
Production-line arrangements and auxiliary equipment can be selected according to bag dimensions, output requirements and available installation space.
Bag Types and Applications
Flat Bags: Suitable for compatible flat bags used for clothing, footwear, retail products and general merchandise packaging.
Shopping Bags: Processes compatible plastic film for shopping bag production. The required sealing structure and cutting arrangement depend on the finished bag design.
T-Shirt Bags: T-shirt bag production requires the appropriate handle-forming or punching equipment. Confirm handle dimensions and bag specifications before selecting the configuration.
Packaging Operations: Suitable for plastic bag production serving retail packaging, merchandise packaging and related applications involving compatible film materials.
Working Process and Control
Automatic Film Feeding: The feeding system delivers film from the roll into the processing section. Appropriate tension and alignment settings help maintain stable film movement.
Computerized Length Control: The control system sets the target bag length and coordinates film feeding with the sealing and cutting cycle.
Heat Sealing: The sealing unit applies controlled heat to form the specified seal. Temperature and sealing time are adjusted according to film properties and bag construction.
Cold Cutting and Counting: The cutting unit separates the finished bags. Automatic counting can be included according to the selected configuration to support batch quantity control.

Material and Production Compatibility
Film Materials: HDPE and LDPE are common materials for this machine category. Confirm the resin type, film thickness, roll width and feeding requirements before production.
Printed Film: Printed film processing may require photoelectric color-mark tracking. The printed layout and registration marks should be checked against the intended cutting position.
Bag Dimensions: Provide the required minimum and maximum bag width and length. The selected model must accommodate the specified dimensions and bag structure.
Customization and Configuration
Bag Design: Configuration can be assessed according to bag dimensions, handle design, sealing structure and cutting requirements.
Output Requirements: Production-line quantity, drive configuration and auxiliary equipment can be evaluated according to the required output and product mix.
Electrical Supply: Voltage, frequency and installed power must match the intended factory electrical supply.
Optional Equipment: Photoelectric tracking, automatic collection and compatible punching equipment can be evaluated according to the required production process.
Output Quality and Production Evaluation
Bag Dimensions: Check finished-bag width, length and cutting position against the specified tolerances. Correct length settings and stable film feeding support consistent dimensions.
Seal Quality: Evaluate seal continuity and strength using the intended film material and thickness. Temperature and sealing time should be adjusted to the selected material.
Cutting Quality: Inspect cut edges and bag separation during production trials. Blade condition and cutting settings influence the finished result.
Production Rate: Assess output using the actual bag dimensions, film specifications and selected production-line arrangement. Confirm expected output under agreed operating conditions.
Installation and Order Confirmation
Installation Space
Confirm machine dimensions, operating clearance, film-loading access and finished-bag collection space before installation.
Electrical Requirements
Specify the available voltage and frequency to ensure compatibility with the selected electrical configuration.
Technical Documentation
Confirm the equipment list, operating instructions, electrical diagrams and installation requirements before shipment.
Production Testing
Agree on sample bag dimensions, sealing quality, cutting quality and output evaluation criteria before final acceptance.
Frequently Asked Questions
Q: What types of bags can this machine produce?
A: It can produce compatible flat bags and selected shopping bag formats. T-shirt bags require the appropriate handle-forming or punching configuration.
Q: Can it process printed plastic film?
A: Yes, when compatible photoelectric color-mark tracking is included. Confirm the print layout and registration requirements before ordering.
Q: What is the difference between cold cutting and hot cutting?
A: Cold cutting uses a blade to separate the film without relying on a heated cutting edge. Heat sealing can be performed separately to form the bag seal.
Q: Can the machine be customized?
A: Yes. Configuration can be assessed according to bag dimensions, film specifications, production targets, electrical requirements and auxiliary equipment.
Q: What information is needed to select a machine?
A: Provide the bag type, finished dimensions, film material, film thickness, printed or unprinted status, target output and local power supply.
