PE Film Secrets: What Sets Pads and Diapers Apart

— And How Sanvera Customizes for Every Need

In the world of hygiene products, not all PE films are created equal.

At first glance, it may seem that sanitary napkins and baby diapers use similar types of polyethylene (PE) films—but the reality is that each product category has very specific needs. At Sanvera, we understand these differences deeply and provide targeted PE film solutions to match.

Let’s break down the key technical differences—and show you how our films support better performance and sustainability across product lines.

1. Functionality: One Material, Different Missions

Sanitary Napkins: PE film acts as a leak-proof backsheet, needing to be thin, reliable, and printable.
Baby Diapers: PE film functions as a breathable outer layer, combining comfort and leakage protection.

Sanvera offers both breathable and non-breathable PE films, engineered to match the functional needs of each product type. OEM support allows full customization of film thickness and width to your production lines.

2. Breathability: A Key Differentiator

Sanitary napkins often use non-breathable films to maximize leakage protection.
Diapers demand breathable PE films—or laminated films—to ensure all-day comfort and prevent rashes.

💨 At Sanvera, our breathable films have stable MVTR (moisture vapor transmission rate) and excellent softness, ensuring skin-friendly wear without compromising barrier protection.

3. Softness & Sensory Comfort

Diaper films must feel soft and cloth-like, often using PE + nonwoven laminates.
Napkin films can be slightly stiffer but still smooth to touch.

🧵 Sanvera’s “Cloth-Like” PE films are optimized for lamination, offering high bonding strength and uniform thickness, perfect for premium diaper lines.

4. Thickness, Width & OEM Flexibility

Sanvera supports full OEM customization:

🛠 Whether you need ultra-thin films for sanitary pads or wide-width breathable films for adult diapers, we’re ready to meet your specific specs.

5. Going Green: Biodegradable PE Film

🌱 Sustainability matters. That’s why Sanvera now offers anaerobically biodegradable PE film solutions, ideal for brands committed to circular innovation.

♻ These films maintain the same performance as traditional PE while breaking down under landfill conditions—perfect for forward-thinking hygiene manufacturers.

Leakage protection in sanitary napkins
