Sanitary Napkin Back Wood Pulp Paper Roll

Sanitary napkin back wood pulp paper roll is a key material used in the production of sanitary napkins or pads. It is used primarily as a backing layer that prevents leakage while ensuring comfort. Here's a general specification and description of the material:

1. Material Composition:

   • Made primarily from wood pulp, which is derived from natural wood fibers. It is typically bleached to ensure cleanliness and a light color, contributing to hygiene.
   • The wood pulp used is often processed into fluff pulp, which is highly absorbent, lightweight, and soft.

2. Roll Size:

   • Width: Typically ranges from 20 cm to 100 cm or more, depending on the manufacturer’s specifications.
   • Length: Can range from 500 meters to several kilometers, depending on the production needs.
   • The paper is rolled in a continuous sheet form to facilitate easier processing during manufacturing.

3. Thickness:

   • Varies but is generally 0.2mm to 0.5mm thick, depending on the intended end-use.
   • Thickness can affect both the comfort and strength of the napkin.

4. Weight:

   • Usually weighs 70-200 grams per square meter (gsm), depending on the desired absorbency and strength.

5. Absorbency:

   • The pulp is highly absorbent, contributing to the sanitary napkin’s ability to hold fluid and keep the user dry.

6. Color:

   • It is typically white, as it’s bleached during the production process to maintain hygiene and ensure there are no colorants that could irritate sensitive skin.

7. Pore Structure:

   • The paper roll is designed with a porous structure to ensure fluid retention, and it may have enhanced absorbency to keep the napkin dry and leak-proof.

8. Softness:

   • The back pulp paper should be soft to the touch, as it makes up the side that comes in contact with the user's skin.

9. Strength:

   • Should have enough tensile strength to prevent tearing during use. Typically, this paper should be strong enough to maintain the napkin’s structural integrity, even when it is wet.

10. Other Treatments:

• Coating: Sometimes, a polymer coating or hydrophobic treatment is applied to the wood pulp paper to prevent liquid from passing through. This enhances the leak-proof quality of the sanitary napkin.
• Antimicrobial Treatment: Some manufacturers apply antimicrobial agents to the paper to reduce bacteria growth.

Sanitary napkin back wood pulp paper rolls serve as a base layer in sanitary pads, positioned between the absorbent core (usually a combination of absorbent fluff pulp and superabsorbent polymers) and the outer layers (often made from nonwoven fabric). This back layer plays a crucial role in providing leakage protection and keeping moisture from leaking onto clothing or bedding.

• The porous nature of the wood pulp allows it to trap liquids, while the hydrophobic coatings prevent leakage from the back of the napkin.
• The fluff pulp used is typically processed to enhance its absorbent capacity and softness, ensuring that the product remains comfortable while still offering high absorbency.
• This material is designed for high-volume, continuous production to ensure consistency in every napkin and to improve cost-efficiency for large-scale sanitary napkin manufacturers.

• Sanitary Napkins/Pads: As a back sheet for protection against leaks.
• Diapers: Used as a part of the back layer in disposable baby diapers.
• Incontinence Products: Used in pads and liners designed for adult incontinence.

The key to a successful sanitary napkin back wood pulp paper roll lies in achieving the right balance between absorbency, comfort, and leakage protection, making this an essential component of sanitary product manufacturing.
