| Product Compatibility | Flexible Configuration
Day-use, night-use, winged, non-winged, ultra-thin, and maxi sanitary napkins can be supported when the corresponding forming and folding modules are installed. | A modular line allows manufacturers to produce several product formats without purchasing a completely different production system for every design. | Request confirmed product drawings, dimensions, material specifications, and sample output for every intended napkin type. |
| Production Speed | Approximately 500–1,200 pieces/min
Actual speed depends on product structure, absorbent core design, packaging format, and quality-control requirements. | Higher nominal speed can improve output, but stable operation and acceptable rejection rates are more important than maximum speed alone. | Compare the guaranteed continuous speed with the line’s tested speed using the buyer’s actual raw materials and product specifications. |
| Material Feeding | Multi-Material Unwinding
Common materials include nonwoven topsheet, PE film, tissue, absorbent paper, fluff pulp, SAP, release paper, and packaging film. | Accurate and stable feeding helps maintain consistent product dimensions, absorbency, sealing quality, and material consumption. | Check tension-control devices, automatic splicing, material-width range, roll diameter limits, and compatibility with the planned raw materials. |
| Absorbent Core Formation | Controlled Pulp and SAP Distribution
The forming system should support uniform pulp shaping and controlled superabsorbent polymer dosing according to the product recipe. | Core uniformity directly affects liquid absorption, rewet performance, thickness consistency, and user comfort. | Review core-weight tolerance, SAP dosing accuracy, dust-control design, forming-mold changeover, and test results for absorbency uniformity. |
| Sealing and Cutting | Ultrasonic or Heat Sealing
Sealing and die-cutting systems are selected according to the topsheet, backsheet, wings, adhesive pattern, and required edge appearance. | Reliable sealing reduces leakage risks, delamination, loose edges, and irregular product shapes during use and packaging. | Inspect seal strength, cutting accuracy, edge smoothness, tooling life, adjustment range, and the availability of replacement dies. |
| Line Automation | PLC and Touchscreen Control
Modern lines commonly use PLC-based control, servo drives, recipe storage, alarm records, and coordinated speed adjustment. | Automation improves repeatability, simplifies parameter management, and helps operators identify faults more quickly. | Confirm control-language options, electrical standards, remote diagnostic capability, data backup, password levels, and operator training. |
| Quality Inspection | Online Defect Detection Options
Available inspection functions may include missing-material detection, splice detection, length measurement, packaging inspection, and metal detection. | In-line inspection can reduce the number of defective products reaching packing and supports more consistent batch quality. | Identify which inspection functions are included as standard, which are optional, and how rejected products are separated and recorded. |
| Changeover Performance | Tooling and Recipe-Based Changeover
Changeover time varies widely; a well-designed line uses quick-adjustment mechanisms, stored recipes, and clearly marked settings. | Shorter changeovers increase available production time when multiple sizes, absorbency levels, or packaging formats are manufactured. | Ask for a documented changeover procedure and observe a full conversion between two representative product specifications. |
| Electrical and Utility Requirements | Three-Phase Industrial Power
Many production lines use three-phase electricity and require compressed air; exact voltage, frequency, air pressure, and consumption are project-specific. | Utility compatibility affects installation cost, operating stability, factory layout, and the selection of auxiliary equipment. | Obtain the final electrical load list, compressed-air consumption, recommended air quality, grounding requirements, and factory-space drawings. |
| Packaging Integration | Individual and Multipack Options
The line may integrate individual wrapping, three-fold or four-fold folding, multipack counting, bag making, sealing, and date coding. | Integrated packing reduces manual handling and helps maintain accurate count, hygienic separation, and consistent package appearance. | Confirm pack-count range, film dimensions, sealing temperature range, coding method, changeover time, and compatibility with retail packaging. |
| Hygiene and Factory Layout | Controlled Production Environment
Production areas should support cleanable surfaces, organized material flow, dust management, personnel controls, and separation of finished goods from waste. | Sanitary napkin production requires disciplined environmental and personnel practices to reduce contamination and protect product quality. | Review the proposed layout, cleaning access, waste-removal route, material storage conditions, and the supplier’s hygiene recommendations. |
| Safety Protection | Guarding and Emergency Controls
A reliable line should include machine guarding, emergency-stop devices, interlocks, warning labels, and protection around rotating and cutting parts. | Proper safeguards reduce risks during operation, cleaning, maintenance, and tooling changes. | Check the risk assessment, guarding design, emergency-stop locations, electrical protection, lockout procedures, and safety documentation. |
| Energy and Material Efficiency | Waste-Control Features
Servo drives, optimized forming, accurate dosing, automatic splicing, and controlled trim collection can help reduce energy use and material waste. | Lower waste improves production economics and supports more predictable consumption of high-cost materials such as SAP and specialty films. | Request actual material-consumption data, average scrap rate, compressed-air usage, installed power, and test conditions used for the calculations. |
| Testing and Acceptance | Factory and Site Acceptance Tests
Acceptance should cover speed, dimensions, weight, absorbency-related tests, sealing quality, packaging accuracy, noise, and safety functions. | Clearly defined acceptance criteria reduce disputes and confirm that the completed line meets the agreed production objectives. | Prepare a signed FAT and SAT checklist with approved raw materials, test duration, sampling frequency, tolerances, and procedures for corrective action. |
| After-Sales Support | Installation, Training, and Spare Parts
Support commonly includes installation guidance, commissioning, operator training, maintenance manuals, electrical drawings, and recommended spare-parts lists. | Responsive technical support helps reduce downtime and improves the line’s long-term maintainability. | Confirm response times, remote-support methods, warranty coverage, engineer availability, spare-parts lead times, and training scope in the contract. |
| Compliance Documentation | Technical and Safety Records
Documentation may include manuals, wiring diagrams, pneumatic diagrams, component lists, maintenance schedules, risk assessments, and conformity documents where applicable. | Complete documentation supports safe operation, regulatory review, maintenance planning, and future line modifications. | Require document formats and languages before delivery, and verify that the documents match the actual installed components and machine configuration. |
