When it comes to diapers, the outer layer might not always get the spotlight, but it plays one of the most crucial roles.
That layer is called the backsheet film, and it determines how soft, breathable, and leak-proof a diaper truly is.

What is Diaper Backsheet Film

The backsheet film is the outermost layer of baby and adult diapers. It prevents liquid leakage and ensures dryness, while also contributing to the overall comfort of the product.

Depending on the material and processing technology, backsheet films can be divided into three main types:

1. Breathable PE Film (Microporous Film)

This film allows air and water vapor to pass through tiny micropores, while blocking liquid water.
It provides a comfortable and dry wearing experience, especially for long-term use.

Key Features:

• High breathability that reduces heat and humidity.

• Soft and cloth-like hand feel.

• Prevents diaper rash by improving air circulation.

• Widely used in premium baby diapers and adult incontinence products.

2. Non-Breathable PE Film

The non-breathable PE film is a solid polyethylene layer that offers superior waterproof performance.
It is more cost-effective and provides excellent leakage protection, making it ideal for economic diaper ranges or underpads.

Key Features:

• 100 percent waterproof barrier.

• Smooth surface and strong mechanical strength.

• Compatible with printing and lamination.

• Used in standard baby diapers, sanitary pads, and pet pads.

3. Laminated Film (PE plus Nonwoven Fabric)

The laminated backsheet film combines PE film with nonwoven fabric, achieving both protection and softness.
It has a cloth-like texture and enhances the premium feel of diapers and sanitary products.

Key Features:

• Soft, textile-like surface for a comfortable touch.

• Excellent waterproof and breathable balance.

• Printable with brand logos or patterns.

• Available in white, blue, pink, or customized colors.
