After bag making, handled paper bags usually require additional processes such as handle attachment and bonding, and separated processes can increase semi-finished product handling and production waiting time. The RZFD-450ATF paper bag machine with twisted handle inline continuously integrates roll paper unwinding, bag making, gluing, square bottom forming, automatic handle attachment, cutting, and collection, allowing the paper to complete handled bag processing along a defined production workflow and reducing downstream processing. The machine can be used for medium-size products such as supermarket shopping bags, apparel handled bags, bakery gift bags, and takeaway bags, making it suitable for packaging enterprises handling batch orders for different applications.
The machine adopts a synchronized servo control system to coordinate paper feeding, forming, and handle attachment, while the photoelectric positioning system adjusts the paper running position, helping reduce web deviation, wrinkling, and inconsistencies between pre-printed graphics and bag positions. For commonly used materials such as kraft paper, greaseproof coated paper, pre-printed paper, and white cardboard paper, the processing conditions can be adjusted according to paper thickness and surface characteristics. The handle attachment mechanism works in coordination with the bag body feeding rhythm, maintaining a consistent relationship between handle position, bonding areas, and the bag bottom structure, providing support for the load-carrying performance and appearance consistency of finished bags.
The touchscreen system can store multiple sets of product settings, allowing the corresponding parameters to be recalled when changing bag types, paper materials, or order specifications and reducing the impact of repeated setup on production scheduling. Protective shutdown functions for material shortage, paper jams, overloads, and web deviation allow operators to inspect abnormalities in a timely manner, while the automatic lubrication structure supports routine maintenance. For packaging plants handling multiple types of handled paper bag orders, the machine provides effective coordination between process integration, order changeover efficiency, and finished product management, providing an equipment foundation for the continuous processing of square bottom handled paper bags.
