What Is Breathable PE Film of Diaper? How To Make Diaper Breathable Film?

Breathable film is an environmentally friendly, breathable water (liquid, bacteria, dust) functional material. The emergence of microporous breathable film has a history of more than 20 years, the last 10 years has been rapid development.

Breathable film is a necessary material for diapers, mainly used as the bottom material of diapers, the main purpose of PE breathable bottom film is to prevent leakage.

THE BREATHABLE PRINCIPLE OF BREATHABLE FILM

The so-called breathable film, is through the polyolefin raw materials uniformly added to mix a functional inorganic products, so that the products in the film-forming process due to high-fold stretching and produce air holes, so as to have breathable, moisture-conducting function.

PE breathable film is in the LDPE / LLDPE polyethylene resin carrier, add about 50% of the special calcium carbonate for blending, after extrusion into a film after directional stretching for a certain number of times and become. As the polyethylene resin for thermoplastic plastic materials, can be stretched and crystallized under certain conditions, stretching polymer and calcium carbonate particles occur between the interfacial stripping, calcium carbonate particles around the formation of interconnected meandering pores or channels, it is these pores and channels to give the film's breathable (wet) function, thus communicating with the film on both sides of the environment.

APPLICATIONS OF BREATHABLE FILMS

Breathable films are used in diapers, sanitary napkins, medical mattresses, etc. There has been a steady demand in Europe and the U.S. and other countries, and the domestic sanitary materials market is bound to mature along with the demand for functionality and comfort, and the demand for breathable films is bound to have more and more space.
