As the leading disposable diaper PE film factory and manufacturer in China, our PE film can be used in a variety of applications, such as women's sanitary napkins and sanitary pads, baby & adult diapers, disposable medical protection products, surgical coats, caps, shoe cover, and industry protection products.





PE Film For Diaper

PE film is one of the raw materials used in baby diapers for packaging film and backing. It has good breathability, water resistance, softness and optimal physical properties. And the good uniformity and tactility are friendly to baby diapers.


Types of PE film

1) Breathable and non-breathable PE film

2) Plain embossed and pressure embossed PE film

3) Breathable and non-breathable laser PE film

4) Printed PE film (multi-color, indicative ink, full printing, etc.)

5) Silicone release film (for sanitary napkins packaging or individual packaging)



Is Diaper PE Film Breathable?

The diaper PE film is usually a composite of nonwoven polyethylene (PE) film. Breathable diaper PE films are mostly used in baby diapers when the health of the infant is considered to keep the skin dry. The diaper PE film has a positive effect on the infant's skin, especially in terms of occlusion and diaper dermatitis.

More About the Breathable PE Film

Breathable PE film is a new type of breathable and impermeable material in the world, whose main component is polyethylene. To be precise, it is a polymer material synthesized from polyethylene. Because of its soft and skin-friendly, high tensile strength and good moisture permeability, it is widely used in various fields, such as women's sanitary napkins, padding film, baby diapers, diapers, etc.


Meanwhile, breathable PE film is also the most important material for medical mask packaging. Breathable PE film is also known as breathable film. Presently, diapers (including baby diapers and adult diapers), sanitary napkins, mommy napkins, etc., basically use breathable PE film, and the breathability is about 2000-2500.



Features Of Breathable PE Film

  • Excellent air permeability. The breathable diaper backsheet film can pass through gas but not water, so it can not only isolate moisture effectively but also discharge heat and moisture. It can be used as waterproof material with a moisture-proof function.


  • Skin-friendly and soft. Breathable PE film has an excellent hand feel, and products made of it are soft and comfortable. Compared with ordinary non-breathable film, it is less likely to cause red bottom problems such as eczema to babies' delicate skin.


  • Excellent tensile strength and extensibility. The breathable disposable diaper PE backsheet film can properly improve air convection in the user's small environment and is conducive to skin breathing.


  • Green and environmental protection. Due to the characteristics of its raw materials, breathable PE film is a new environmentally friendly material that does not damage the environment. Meanwhile, its chemical resistance is good and not easy to corrode.



Principle Of Breathable PE Film

Breathable PE film is made of LDPE/LLDPE polyethylene resin, blended with about 50% of special calcium carbonate, and extruded into film after directional stretching at a certain speed. Since polyethylene resin is a thermoplastic material, it can be stretched and crystallized under certain conditions.


During the stretching process, the interface between the polymer and the calcium carbonate particles is peeled off, and interconnected sinuous pores are formed around the calcium carbonate particles. Or channels and these pores and channels give the membrane its breathable (wet) function, thus communicating the environment on both sides of the membrane.



Usage Range Of Breathable PE Film

  • Sanitary products: diapers, sanitary napkins, medical surgical gowns, special medical packaging, food packaging, etc.
  • Daily necessities: raincoat, suit jacket, eye mask, tablecloths, shower cap, shower curtain, water bag, tablecloth, etc.
  • Packaging supplies: computers, dust covers for air-conditioning appliances, car covers, soft packaging for cosmetics, shopping bags, gift bags, folders, etc.
  • Packaging bags: fashion packaging, cosmetic bags, advanced stationery, embracing saliva shoulders, closets, fishing bags, handbags, and other product applications.



The Main Raw Materials For Diapers And Sanitary Napkins

1) PE film, laminated film (cloth-like film)

2) PP side tape, hook side tape and PP frontal tape, hook frontal tape

3) Hot melt adhesive (spandex/structure), backing glue

4) Treated/untreated fluff pulp

5) SAP

6) Nonwoven

7) Spandex/elastic waistband

8) Quick and easy tape for sanitary napkins

9) Release paper (with wings or back of sanitary napkins)

10) Sap absorbent paper, air-laid paper

11) Perforated PE film, perforated nonwoven



Why Choose The Breathable PE Film For Diaper?

PE film is one of the main raw materials of baby diapers, adult diapers, sanitary napkins and diapers, which is breathable and soft after stretching. Thus, it is often used for baby diapers, waterproof to protect the baby's delicate skin from harm.


  • Excellent waterproof performance
  • Best physical function
  • Non-toxic, tasteless, and harmless to human
  • Excellent printing performance
  • Soft and silk hand feeling


The breathable PE film is mainly used for the backsheet film of the baby/adult diaper. However, it also can be applied to sanitary napkins, disposable mattresses and more disposable personal healthcare products.



Breathable PE Film For Medical Field

Breathable films are manufactured from laminated polyethylene by extrusion technology. This film is permeable to gases and water vapor, but not to water in its liquid state. It is non-toxic, odorless, corrosion and tear-resistant, resilient at both low and high temperatures, easy to decompose and recycle, and waste disposal without causing harm to humans or the environment.


The breathable PE film is suitable for hygiene applications. It is often designed to manufacture disposable hygiene products, baby diapers, sanitary napkins, incontinence pads and supplies for chronic patients. Contribute to user comfort - their permeability allows the skin to breathe better and reduces the occurrence of potential adverse side effects such as rashes, ulcers, etc.
