Straight Strip Package Sanitary Napkin Production Line

Full-Servo Strip-Wrap Sanitary Napkin Production Line

This is a high-speed, fully automated production line specifically designed for manufacturing strip-wrap sanitary napkins – individually wrapped sanitary pads that are hygienically sealed in a thin film, offering superior portability and a higher retail value. “Strip wrapping” refers to the process where each pad is individually sealed in a strip film. This packaging format is highly preferred by premium brands and in export markets for its enhanced hygiene and convenience.

The core technology of this line is its full-servo drive system, which ensures precise synchronisation, digital size changeovers, and superior product quality at high production speeds.

Core Systems & Features

A typical full-servo strip-wrap sanitary napkin production line comprises the following core systems and features:

• Product Structure: The line processes multiple material layers including: flat or textured topsheet, ADL (acquisition distribution layer), fluff pulp or airlaid core (mixed with SAP), backsheet, absorbent paper, release paper, and pouch film-. It can be configured to produce both cotton-core and ultra-thin (airlaid) sanitary napkins-.

• Strip-Wrap Packaging System: After forming, each sanitary napkin is individually wrapped and sealed in a thin strip film. This process ensures product hygiene and portability.

• Drive & Control System: Full-servo motors drive all critical stations, ensuring precise synchronisation. Operators can set parameters, monitor operations, and manage production via an intelligent HMI touchscreen (PLC-based man-machine interface)-. The system supports digital size changeover, allowing quick switching between different product sizes-.

• Tension & Web Handling: Equipped with tension control with buffer system and automatic web guiding systems to maintain flat and stable material travel at high speeds-. Key stations feature zero-speed splicing technology for non-stop roll changes.

• Quality Control System: Integrated inline detection systems monitor pad position, size, sealing, and film alignment. Faulty products are rejected automatically. Advanced systems can also include vision detection and metal detection.

• Safety System: Designed according to European CE standards and CE certified. Equipped with safety guards on the operating side, emergency stop switches, safety doors, and other protective devices-.

• Packaging System: Includes an automatic stacker and packaging machine, customisable according to customer requirements.

• Precision Manufacturing: Most spare parts are manufactured by numerical control precision processing; key mechanical parts are CNC machined; major outsourced components are from world-famous brands-.

Key Technical Parameters

Specific values may vary by manufacturer and model. The table below summarises common industry ranges based on various manufacturer specifications:

 Advanced Technologies & Customisation Options

• Precision and Speed: With servo control, the machine can achieve timing accuracy down to milliseconds and positioning accuracy within ±1mm, ensuring every pad has the same size and quality.

• High Automation: The line can operate at high speeds with minimal manual intervention, significantly improving production efficiency-.

• Modular Design: Modern lines are modular for easy maintenance and future upgrades-.

• Customisation: Manufacturers offer extensive customisation options, including jumbo roll auto-splicing servo control, full-servo control stacker, automatic bagging sealing machine, and other tailor-made solutions.

• CE Certification: Designed and manufactured in compliance with European CE standards with safety protection devices.
