Specifications

  • Breathable laminates Fatra Sontek®L are manufactured by laminating breathable film and non-woven fabric.
  • The laminates are permeable for gases and water vapours but impermeable to water in liquid state.
  • Suitable for hygienic applications, the laminates are designed for use in the manufacture of disposable sanitary products – baby diapers, sanitary towels, incontinence pads and supplies for the chronically ill.
  • They help to enhance user comfort – their permeability allows the skin to better breathe, reducing the potential occurrence of undesired side effects such as skin rash, sores etc.
  • Using fleece in the laminate gives the product texture and appearance of textile.
  • laminates can be supplied in white or printed version up to eight colours.

 

THE PRINCIPLE OF VAPOUR PERMEABILITY
Breathable film is very thin sheet containing about 1,4 billion pores/cm2. A single pore is 700 times larger than a molecule of water vapour and 20 000 smaller than a drop of water. The actual pore size is 2-3 microns. It provides high vapour permeability and liquid impermeability of the product.

STRUCTURE OF BREATHABLE PE FILM

POSITION OF FATRA SONTEK® L IN HYGIENIC DISPOSABLE PRODUCT

The film in laminate avoids liquid to get out of the product while letting circulate the gases and water vapour. Thanks to this, the skin is able to breathe while staying dry and not irritated by liquids.
