Principles of using breathable films

1. The air permeability effect is the inherent characteristic of the breathable film, and the structural design of personal hygiene care products is the key.

2. As a waterproof material, the safety (water insulation) of the breathable film is the premise, and only on the premise of ensuring safety can the permeability be talked about.

3. " Relatively wide ", "thin, close-fitting", "relatively closed" type structure and relatively long time use (such as diapers, pads, etc.) of care products, the use of breathable film materials is necessary.

4. Compared with ordinary PE embossed film, breathable film has its inherent shortcomings, so the design of products should be good at avoiding defects and giving play to its strengths. For example, the transverse strength of the breathable film is low, the color is relatively monotonous, and the thermal stability is poor.

5. The final breathable effect is proportional to the actual breathable area of the breathable film. Product design needs to maintain effective ventilation area.

6. The design of the final product should consider the convection of the small environment.

Application of breathable film

Breathable film used in diapers, sanitary napkins, medical mattresses, etc., in Europe and the United States and other countries has been a stable demand, and the domestic hygiene materials market will mature with the demands of functionality and comfort, the demand for breathable film space will be more and more large.
