Fatra’s Tenolan® biaxially oriented polyethylene terephthalate (BOPET) films are extruded films with subsequent biaxial orientation. Such film is designed for further processing by packaging technology, in the electrotechnical industry, for decoration purposes, as separation foils, etc. It is supplied on rolls or cut to size. It is specifically designed for direct contact with foodstuffs and meals and must comply with any hygienic regulations in force.
PET (polyethylene terephthalate) is a hard and clear polymer material with extremely good mechanical features. It shows excellent tear resistance; it can resist high pressures without breakage; it is used to produce packaging for beverages – PET bottles.
PET material is also suitable for the production of extruded foil. Subsequent biaxial stretching of the foil (in both directions) significantly improves strength in both directions. It is used as a packaging material in gift packs or as baking foil. In foil form, PET is highly resistant to steam and gas permeability, thereby providing protection to the packaged products, while also being resistant to the effects of the oils and fats in the packaged foodstuffs.
PET can be combined with other materials to create multi-layer packaging, the features of which are modified for the specific application – the packaging of aromatic spices, cheese, smoked meat, etc. Upon request, such foils may possess different colours, be imprinted or metal-coated (cosmetics, toothpaste) or laminated (packaging for pet feed).
Typical examples of PET applications include:
Fibres in the textile industry – dressmaking, winter jacket wadding (padding).
Bottles for beverages, in particular for sparkling and alcohol-free liquids.
High-speed boiling pouches, precooked food bags, packaging for non-perishable food.
PET is easily recyclable. PE bottles sorted from municipal waste are frequently reprocessed into fibres.
Aluminium (chemical symbol Al, Latin title Aluminium) is a very light metal of a whitish-grey colour and a very good conductor of electrical current. It is widely employed in electronics and in alloys for aircraft, as well as many other applications.
Aluminium is popular due to its relatively high chemical resistance and low weight. Rolling it into a thin foil results in kitchen foil, which is used in baking and roasting or as a protective packaging material for various applications.
Aluminium is also employed to produce flexible packaging foils. An aluminium layer is usually steamed onto plastic foil by electrical discharge in a vacuum.
Applications
Packaging PET films – for the production of flexible packaging for foodstuffs and technical products.
Electrical-insulation films – for producing cables, transformers, and the winding insulation of electric motors.
Other films– production of labels, adhesive tape, siliconized foil, identification and payment cards, office supplies.
