Material Buying Guide

This silicone coated release paper is a critical component in the production of disposable hygiene products, primarily serving as a protective liner for adhesive zones on sanitary pads and panty liners. Its primary function is to protect the adhesive before use and to release cleanly and easily when the product is applied, ensuring a secure fit without damaging the product's structure.

For purchasing and R&D teams, this material offers a balance of key performance attributes. The 42 gsm basis weight provides dimensional stability and sufficient stiffness for efficient handling on converting lines, while the silicone coating delivers the controlled release characteristics necessary for high-speed processing. The available width range of 25 mm to 960 mm offers flexibility for various production setups and product sizes.

Key verified specifications include:

• Basis Weight: 42 g/m² (±2 g/m²)
• Whiteness: 80-85%
• Moisture: 8% ± 2%
• Breaking Tension: ≥ 45 N/25.4mm
• Peeling Strength: 0.08 - 0.25 N/25mm

Functional Benefits: The material is designed to offer a smooth, consistent surface for reliable adhesive coverage and release. Its visual properties—including color and cleanliness—are controlled to meet the aesthetic requirements of hygiene products. The roll dimensions and core size are standardized to fit common converting machinery.

Sampling and Packing: For evaluation purposes, samples can be arranged to assess the material's performance on your specific production line. Standard packing is in rolls, with a typical loading quantity of 15 tons per 20GP container.

Application and Compatibility

This silicone coated release paper is positioned as a high-performance liner for the hygiene industry. It is specifically designed to be compatible with the adhesive systems and high-speed processes used in the manufacture of sanitary pads and panty liners.

Material Position in Production: It is typically used as the bottom protective layer, covering the adhesive that secures the product to underwear. It can also be used as a release liner for individual adhesive strips or wings.

Compatible Substrates and Process Steps: The material is designed to work with standard hot-melt adhesive application systems. Its controlled release properties ensure that the liner can be cleanly removed from the adhesive without leaving residue or causing tearing. It is suitable for use in rotary and intermittent converting processes.

Production-Line Considerations: The 76 mm inner core diameter is a standard size for most converting lines, ensuring easy mounting. The roll's outer diameter of 460 mm allows for extended production runs, reducing downtime for roll changes. The material's tensile strength is designed to withstand the tension of high-speed unwinding and lamination processes.

Quality Checkpoints: Incoming quality control should verify the roll dimensions, basis weight, and visual appearance. During production, monitor the release force to ensure it remains within the specified range of 0.08-0.25 N/25mm for consistent performance.

Specifications: For detailed physical properties, please refer to the Technical Specifications section. Final configuration and suitability for your specific process should be confirmed through material trials.
