Sanitary Napkin Back Release Paper Roll

S3 Sanitary napkin back release paper rolls are an essential component in the manufacturing of sanitary napkins. This paper is used as the release liner that covers the adhesive layer, preventing the adhesive from sticking to unwanted surfaces during storage and handling.

Specification of Sanitary Napkin Back Release Paper Roll:

1. Material:

   • Typically made from siliconized paper or polyethylene-coated paper.
   • The paper is coated with silicone to provide smooth release properties.

2. Thickness:

   • Typically ranges from 40 to 80 GSM (grams per square meter).
   • The thickness may vary based on manufacturer requirements or the design of the sanitary napkin.

3. Width:

   • Common roll widths range from 150 mm to 800 mm, depending on the size of the sanitary napkin being produced.

4. Length:

   • The roll length can vary from 500 meters to 2000 meters per roll. It depends on the production scale and the specific needs of the manufacturer.

5. Weight:

   • Usually between 10 to 50 kilograms per roll, depending on the thickness, width, and length of the roll.

6. Color:

   • Typically white or natural (brown), though sometimes it can have a slight off-white tint due to the coating process.

7. Adhesive Layer:

   • There is a layer of silicone coating on one side, allowing easy peeling from the sanitary napkin's adhesive layer.
   • The release paper is treated to ensure that the adhesive sticks to the sanitary napkin pad during use but doesn’t interfere with the removal process during manufacturing or packaging.

8. Release Force:

   • The release force is typically measured in grams per inch or grams per meter and indicates how easily the paper can be removed from the adhesive. A typical release force could be between 20 to 50 grams per inch, though this can vary.

Key Features:

• Silicone Coating: The paper is treated with a silicone coating to create a smooth, low-friction surface that allows for easy separation from the adhesive.
• Strength and Durability: The release paper is designed to be strong enough to withstand the handling during manufacturing, yet it should peel off without tearing or damaging the adhesive underneath.
• Lightweight and Non-Toxic: The paper is typically lightweight and safe for use in products that will be in contact with sensitive skin.
• Environmental Considerations: Some manufacturers may also use biodegradable or recyclable paper to align with sustainability practices, though this is more common in certain markets.

Function and Purpose:

• Protective Layer: It serves as a protective barrier for the adhesive side of the sanitary napkin during the production, handling, and storage phases.
• Easy Peel-Off: It ensures that the adhesive layer stays protected and does not lose its stickiness or become contaminated until the user removes the back liner before use.
• Hygienic: Provides a clean, smooth surface to protect against contamination before use.

This release paper plays a crucial role in maintaining the hygiene and functionality of the sanitary napkins, ensuring they remain intact and properly sealed until they are ready for use.
