RZFD-330 Square Bottom Paper Bag Machine with Printing Inline — An Efficient Bag-Making Solution for Coordinated Printing and Stable Quality

The RZFD-330 square bottom paper bag machine with printing inline is developed to meet the needs of scaled production. Its design emphasizes coordinated operation between printing and bag-making processes. By integrating the printing process directly with bag forming, this model reduces intermediate handling and process interference, helping users in food, daily chemical, and cultural and creative industries build a more compact and controllable paper bag production workflow.

The machine covers the complete process from roll paper unwinding, printing, and creasing to bag forming, square bottom gluing, and cutting. All related processes are coordinated and managed through a unified control system, ensuring that printing conditions remain synchronized with the bag-making rhythm and avoiding deviations and material loss caused by semi-finished product transfer. In actual production, this integrated approach helps improve overall operating efficiency while reducing manual intervention. During continuous operation, the printing system maintains clear and consistent presentation of patterns and text, meeting basic visual requirements for branded packaging. Paper feeding and positioning control remain stable, ensuring consistent bag dimensions and square bottom forming quality. The gluing and bonding process is continuously regulated by a temperature control system, allowing adaptation to a range of commonly used paper materials. The finished paper bags feature a firm structure, secure bottom sealing, and a clean appearance.

In terms of structure and configuration, the machine adopts a modular design concept. Specification changeover is relatively simplified, making it suitable for production scenarios involving alternating multiple orders, small batches, and regular batch runs. The machine operates stably under continuous production conditions, which helps control material waste and maintain a balanced output rhythm. Key components such as the printing and cutting units are manufactured using durable materials and processes, reducing maintenance frequency during long-term operation and extending the overall service life of the machine. Components and processes related to packaging safety and environmental protection are configured in accordance with common industry requirements, supporting the use of water-based inks and widely used eco-friendly paper materials, and meeting current packaging production needs for compliance and sustainability.

For application scenarios that require both printing quality and production efficiency, the RZFD-330 square bottom paper bag machine with printing inline supports continuous production while maintaining stable printing and bag-making quality. It helps users improve packaging consistency and delivery efficiency, enabling them to better respond to diversified order demands.
