Fatra Sontek®F breathable films – permeable to gases and water vapour but impermeable to water in liquid state – suitable for use in the manufacture of disposable sanitary products – nappies for babies, sanitary towels, incontinence pads/pants and supplies for the chronically ill.
Breathable for gases and vapour, resistant to water permeability in liquid form.
Hygienic without exception, meets standards ČSN EN ISO 10993:5 and 10993:10.
Improvement of user comfort – better skin breathability, reduction of unpleasant side effects such as: skin inflammation, sores, etc.
Tailored to the specific needs of the customer.
Fatra Sontek® F breathable films are manufactured from densely filled polyethylene by extrusion technology.
The films are permeable to gases and water vapour but impermeable to water in liquid state.
The films are matt, soft and pleasant to the touch.
It is possible to print up to eight colours on the film.
The flms are hygienic without exception, suitable for hygienic applications, the films are designed for use in the manufacture of disposable sanitary products – nappies for babies, sanitary towels, incontinence pads/pants and supplies for the chronically ill. The films help enhance user comfort – their permeability allows the skin to breathe better, reducing the potential occurrence of undesirable side effects such as rashes, sores etc.

PE (polyethylene) is the most commonly used plastic in the world. Annual production exceeds 90 million tons. It was developed in 1933. This invention proved essential to the development of modern plastic materials, which have since become indispensable. From a chemical point of view, polyethylene’s structure is very simple; therefore, it can be produced in a relatively easy and inexpensive way. According to its density, polyethylene is classified into two major types: low-density (LDPE) and high-density (HDPE), while a third type is known as linear low-density PE (LLDPE).
Both primary types of PE are easily processed by certain technologies, and products of various shapes and sizes are made from them. In general, polyethylene has excellent strength, high toughness and ductility. Products may be transparent or coloured with pigments. The most common PE processing methods are extrusion (2D products) and injection-moulding (3D products).
The best-known polyethylene applications include:
Flexible packages – o bags for fresh and frozen foodstuffs, shopping bags, extensible foils.
Solid packages – bottles for detergents and cosmetics, canisters, barrels, large containers.
Consumer items – minor kitchen ware.
Tubes and pipes
Polyethylene may be recycled. It is widely present in communal waste, so efforts are made to sort (yellow container for sorted waste) and reuse it.
The film (laminate) is joined to the other components of the hygienic product at the final processing plants. Typical final structure:
internal layer (nonwoven fleece, textile mesh)
intermediate layer (absorption materials of different composition)
internal layer (breathable film or laminate)

This film avoids the release of liquid from products, while still letting gases and water vapour circulate. Consequently, the skin is able to breathe but stay dry and not irritated by liquid.
