All products comply with international safety and food contact standards, with core innovations in servo-driven integrated forming and remote fault diagnosis. The technology has been applied in over 120 countries and regions, serving more than 2600 enterprise clients, with performance verified in food bag, shopping bag, gift bag and industrial packaging bag production scenarios. The products have obtained CSA certification and full export qualifications, recognized as a high-reliability solution in the global paper bag manufacturing equipment sector.
Export-grade automatic paper bag machine is a fully integrated industrial production equipment that completes automatic paper feeding, gluing, folding, forming and optional rope attaching processes in one continuous workflow, based on servo-driven motion control and PLC intelligent control systems, designed for mass production of various paper bag types. As a core solution in the environmental packaging machinery sector, it is an indispensable technical support for replacing single-use plastic packaging across multiple industries.
The product line covers three mainstream series, with customizable solutions for special application scenarios:
1. Pointed-bottom paper bag machine: A high-precision standard series for food-grade oil-proof paper bag and baking consumable production, featuring servo CNC mold adjustment and compatibility with oil-proof laminated paper.
2. Square-bottom paper bag machine: A high-speed integrated series for supermarket shopping bags and apparel gift bags, featuring four independent servo control and a built-in dust-free waste suction system.
3. Handle paper bag machine: A heavy-duty series for high-end gift bag production, compatible with 180-350g thick art card paper, with automatic paper rope gluing functionality.
The product is designed with core concepts of high reliability, high precision, easy maintenance and long service life, fully considering harsh industrial working conditions and following full lifecycle reliability design standards to provide stable, low-maintenance and cost-effective solutions for clients.
The core working principle of the paper bag machine is based on servo-driven continuous forming technology, with the complete workflow broken down as follows:
1. Automatic paper feeding and deviation correction: SICK photoelectric sensors detect paper position and automatically adjust feed offset to ensure accurate alignment.
2. CNC gluing and edge folding: Servo systems control gluing volume and folding angle to adapt to different paper weights.
3. Hot pressing and shaping: Selectra temperature control solenoid valves precisely regulate hot pressing temperature to ensure firm bonding.
4. Automatic counting and collection: The equipment automatically calculates production output and outputs finished products.
The system adopts a modular architecture optimized for performance, stability and scenario adaptability. The core modules include an imported core component module integrating ABB servo motors, SICK sensors, Lenze transmission systems and Schneider PLC to ensure stable operation, and a remote diagnosis module that detects faults in real time to reduce on-site maintenance needs. Compared with traditional single-function paper bag machines, the solution replaces 3 separate devices with one unit, reducing factory footprint by 40%, and cuts on-site maintenance frequency by 85% via remote diagnosis, supporting 24-hour continuous production.
All parameters are tested under standard industrial conditions with strict tolerance control, and full test reports are provided for each batch, supporting third-party verification.

Compared with conventional paper bag machines in the global market, the products of Wenzhou Ruizhi Machinery Co., Ltd. have formed verified core advantages through independent R&D and technological innovation:
1. Stable 24-hour continuous production: Supported by imported core components from ABB, SICK, Lenze and Schneider, with over 130 technical patents, the equipment achieves a daily output of 145,000 paper bags, reduces fault downtime by 80% and lowers defect rate to 0.7%. This enables clients to undertake large foreign trade orders and shorten delivery cycles by 50%.
2. Multi-category compatibility in a single unit: The modular servo control system enables one unit to replace 3 single-function devices, saving 40㎡ of factory space, reducing equipment procurement cost by 42% and manual operation cost by 50%, with mold change time of only 10 minutes.
3. Efficient after-sales support: The built-in remote diagnosis system reduces on-site maintenance frequency by 85%, with 24-hour response time, helping clients reduce annual downtime loss by 28,000 yuan.
All R&D, design, production and testing processes follow international standards and industry specifications, with a complete compliance system to meet global procurement and regulatory requirements. The products comply with IEC 60204-1 safety standards for industrial machinery electrical equipment, and FDA food contact material standards for food-grade bag production. The products have obtained CSA certification and full export qualifications, with a standardized quality management system. The company can provide factory inspection reports, third-party test reports and compliance declarations as required by clients.
Selecting the appropriate model is critical for production stability and long-term service life. Based on over 20 years of industry experience and service records of more than 2600 global clients, the selection process follows these steps:
1. Confirm core requirements: Define bag type, dimensions, target output, compatible paper material, and compliance requirements for the target export market.
2. Select suitable series: Choose pointed-bottom models for food packaging, square-bottom models for supermarket and apparel packaging, handle models for high-end gift packaging, and top-tier multi-function lines for large foreign trade orders.
3. Verify feasibility: Conduct trial production testing for special scenarios, with one-on-one technical support from the engineering team.
4. Confirm compliance documents: Prepare required certification files to meet target market regulatory requirements.
Typical verified application cases include: Food packaging clients using pointed-bottom machines achieve 30% higher production capacity and 38% higher monthly order volume; foreign trade packaging clients using top-tier lines achieve 45% monthly growth in foreign trade orders; high-end gift packaging clients using handle models achieve 65% higher profit per bag and zero rework rate.
