Principles of using breathable membrane：
For the embodiment of the final breathable effect, the inherent characteristics of the breathable film are the foundation, but the structural design of personal hygiene products is the key;
When used as a water-proof material, the safety (water-proof property) of the breathable membrane is the premise, and only under the premise of ensuring safety can we talk about breathability;
“Width-relatively large”, “thin-thin, close-fitting”, “package-relatively closed” structure and care products that are used for a relatively long time (such as diapers, panty liners, etc.), the use of breathable membrane materials is necessary;
Compared with the ordinary PE embossed film, the breathable film has its inherent shortcomings, so the design of the product should be good at avoiding shortcomings and giving full play to its strengths. For example, the transverse strength (CD) of the breathable film is low, the color is relatively monotonous, the thermal stability is poor, etc.;
The final ventilation effect is directly proportional to the actual ventilation area of the ventilation membrane. The effective ventilation area should be cherished and protected during product design;
The design of the final product should consider the convection of the small environment;
There is a time lag in the performance of breathable products on the user.
Application of breathable membrane:
Breathable films are used in diapers, sanitary napkins, medical mattresses, etc., and there has been a stable demand in Europe, America and other countries, while the domestic sanitary materials market is bound to mature with the demand for functionality and comfort. The demand for breathable films The demand space is bound to increase.
