Fatra Sontek®L breathable laminates – 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 vapours, resistant to water permeability in liquid form.
Hygienic without exception, meets standards ČSN EN ISO 10993:5 and 10993:10.
Tailored to the specific needs of the customer.
Improvement of user comfort – better skin breathability, reduction of unpleasant side effects such as: skin inflammation, sores, etc.
Textile in form in touch and appearance.
Fatra Sontek®L breathable laminates are manufactured by laminating breathable film and non-woven fabric.
The laminates are permeable to gases and water vapour but impermeable to liquid.
The fleece in the laminate gives the product texture and the appearance of textile. The laminates can be supplied in white or printed with up to eight colours.
The laminates are hygienic without exception, suitable for hygienic applications, the laminates 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.
They help to enhance user comfort – their permeability allows the skin to breathe better, reducing the potential occurrence of undesirable side effects such as rashes and sores.
Higher breathability levels are available upon request.
Option of anti-microbial treatment.
Lamination with various types of non-woven textiles (standard, high softness, materials with various absorption capacities, and so on).
Flexographic print of up to 8 colours.
Print up to 3 different motives on one roll.
Registered print. random print.
Maximal print width of 1,270 mm.
Printing optionally on PE, PP, PET materials.

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.
Non-woven textiles are plane or mesh formations formed by chemical, thermal or mechanical processes; they are not created by knitting or weaving.
Non-woven textiles are usually made from polypropylene (PP). Non-woven PP textiles comprise thin fibres, several centimetres long, connected mutually by thermal reaction or adhesives.
Non-woven textiles are designed for various applications:
Sanitary items – nappies for babies, incontinence pants.
Health care – disposable sheets for surgical/medical operations.
Automotive industry – thermal and noise barriers, filling materiál.
Technical applications – geotextiles, filtration.
Agriculture – anti-weed textiles, for mulching, etc.
Fatra uses non-woven textiles in its waterproof Fatrafol 807 membrane, and in the production of steam-permeable laminates, such as membranes and surgical wear components.
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)
Applications of breathable films – as a backsheet in the production of disposable hygienic products:

The film in laminate 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.
