Essential Raw Materials of Diaper: What You Need to Know


When it comes to manufacturing high-quality diapers, understanding the raw materials of diaper is crucial. These materials determine the comfort, absorbency, and safety of the final product. In this guide, we’ll explore the types, functions, and sourcing strategies for diaper raw materials, especially from China, a leading global supplier.


Types of Raw materials of Diaper


Diapers are made from several key components, each serving a specific purpose. The primary raw materials of diaper include:

  • Absorbent Core: Usually made of superabsorbent polymers (SAP) and fluff pulp, this layer traps moisture.
  • Top Sheet: A non-woven fabric that stays dry against the baby’s skin.
  • Back Sheet: A waterproof layer, often polyethylene, to prevent leaks.
  • Elastic Components: Used around legs and waist for a snug fit.
  • Adhesives: For securing tabs and layers.

Functions and features of Raw materials of Diaper


Each material plays a vital role in diaper performance. For example, SAP can absorb up to 30 times its weight in liquid, while the top sheet’s softness prevents irritation. The back sheet’s breathability ensures comfort, and elastic components enhance fit to prevent leaks.


Scenarios of Raw materials of Diaper


These materials are used in various diaper types, including disposable, cloth, and biodegradable options. Disposable diapers rely heavily on SAP and non-woven fabrics, while eco-friendly diapers may use bamboo or corn-based materials.


How to Choose Raw materials of Diaper


Selecting the right materials depends on factors like absorbency, skin-friendliness, and environmental impact. Always check for certifications like OEKO-TEX or ISO 9001 to ensure safety and quality.
