This article provides a standardized technical overview of high-speed square bottom shopping paper bag machines, independently developed and manufactured by Wenzhou Ruizhi Machinery Co., Ltd. As a professional packaging machinery supplier with over 20 years of R&D and industrial application experience in the environmental packaging equipment sector, the company focuses on delivering reliable automated paper bag production solutions for global clients. This equipment is designed to address core industry pain points including high floor space occupation from multiple single-function devices, high manual operation costs, unstable 24-hour continuous production, and long offline repair cycles. It strictly follows food packaging production safety standards, with core technical breakthroughs in four-servo independent synchronous control and remote fault diagnosis. To date, the equipment has been applied in over 120 countries and regions, serving more than 2600 enterprise clients, with performance verified in food catering, apparel retail, supermarket packaging and foreign trade order production scenarios. The product has obtained CSA certification, and is recognized as a high-reliability solution in the global paper bag manufacturing industry .
A square bottom shopping paper bag machine is an automated industrial equipment that integrates automatic paper feeding, gluing, creasing, square bottom folding and shaping functions, developed based on four-servo independent synchronous control technology. It can produce handle-free or handle-equipped square bottom shopping bags adapted to multiple paper materials, and serves as a core production solution for the environmental packaging manufacturing sector .
To meet diversified industry and working condition requirements, the equipment covers two mainstream series, with customizable solutions for special scenarios: the standard high-speed series, suitable for conventional supermarket and apparel shopping bag orders, supports bag size adjustment from 100 to 450mm, with a production speed of 70 to 110 pieces per minute; the thickened handle series, suitable for high-end gift and cultural creative packaging orders, can process 180 to 350g thick art card paper, with automatic paper rope pasting function .
The product is designed with core concepts of high reliability, low maintenance and high production efficiency, fully considering the harsh working conditions of continuous industrial production, and following full life cycle reliability design standards .
The core working principle of the equipment is based on four-servo independent synchronous control technology, with a complete operation chain as follows: first, the automatic paper feeding unit delivers raw or printed paper accurately, with a SICK deviation correction sensor to align paper edges; second, the numerical control gluing unit applies food-grade adhesive along preset paths; third, the creasing and bottom folding unit completes square bottom creasing and side folding synchronously; fourth, the shaping output unit compacts the paper bag, while a dust-free waste suction system cleans residual paper scraps .
Compared with traditional single-function paper bag machines, this equipment replaces 3 separate devices with one unit, reducing total equipment procurement cost by 42%, and supporting 24-hour uninterrupted mass production with a daily capacity of 145,000 paper bags. The remote diagnosis function reduces offline on-site repair frequency by 85%, cutting annual downtime loss by 28,000 yuan .
All parameters of the equipment are tested under standardized industrial test conditions, with strict tolerance control. Full parameter test reports are provided for each batch, and third-party testing support is available upon request .

Compared with conventional square bottom paper bag machines in the global market, Wenzhou Ruizhi Machinery Co., Ltd. has formed verified core advantages through independent R&D and technological innovation:
1. High-stability continuous mass production: The equipment integrates core components from global leading brands including ABB, SICK and Lenze, with over 130 technical patents. It supports 24-hour uninterrupted production with a daily capacity of 145,000 paper bags, reducing defective rate from 6.3% to 0.7%. This helps clients shorten order delivery cycle by 50% and undertake large foreign trade orders from the Middle East, Europe and America .
2. Low maintenance cost: The equipment is equipped with a remote fault diagnosis system and dust-free waste suction system, reducing daily cleaning downtime from 90 minutes to 15 minutes, and increasing effective production time by 12%. This cuts annual downtime loss by 28,000 yuan, and reduces on-site repair waiting time by 90% .
All R&D, design, production and testing processes of the equipment strictly follow international standards and industry specifications, with a complete compliance system to meet global client procurement and market access requirements .
The product has obtained CSA safety certification, and the company holds complete import and export qualifications. We can provide factory inspection reports, third-party testing documents and compliance declarations as required, supporting market access for Europe, America, the Middle East and other regions .
Based on over 20 years of industry experience and service cases of more than 2600 global clients, we provide a step-by-step selection guide to help clients avoid selection errors:
1. Confirm core requirements: Clarify the required bag type (handle or handle-free), paper weight (80-250g conventional, 180-350g thickened), daily production capacity, and target market compliance requirements.
2. Select the appropriate series: Choose the standard high-speed series for conventional supermarket and apparel orders, or the thickened handle series for high-end gift and cultural creative packaging orders.
3. Verify feasibility: For special working conditions, sample testing and one-on-one technical engineer guidance are provided to ensure adaptability.
4. Confirm customization requirements: Non-standard bag sizes, special paper material adaptation and other customized functions can be adjusted based on client needs .
Typical verified application scenarios include: food catering and bakery packaging, where the equipment supports oil-proof laminated paper processing, reducing defective rate to 0.7% and increasing monthly order volume by 38% for clients; apparel foreign trade and cultural creative packaging, where the thickened series reduces handle pasting defective rate to 0.4%, increasing single bag profit by 65%; supermarket fresh packaging, where the dust-free suction system reduces breakage complaints by 76% and increases repurchase orders by 32% .
