NOVAMONT UNVEILS ITS INNOVATIVE BIODEGRADABLE AND COMPOSTABLE CLINGFILM

The clingfilm which can also be used for foodstuffs with a high fatty acid content and with acidic foods, is easy to tear off and contains renewable resources of agricultural origin.

Novamont continues the development with its Second Generation Mater-Bi® products: at the K fair (the international trade fair for plastics and rubber), taking place in Düsseldorf from 27 October to 3 November 2010, Novamont will be unveiling its first industrial clingfilm that is biodegradable and compostable and contains renewable resources.
The stretchy clingfilm can be used for any kind of foodstuffs, even food that has a high fat content (oils, sauces, butter, etc.) or that is acidic. After use it can be disposed of as organic waste as the material has been certified as compostable in accordance with standard EN13432 and is compatible with various kinds of composting plant technology.
The product was developed by Novamont together with its partners and has the same technical characteristics of strength and stretch as traditional products developed for domestic use without using any plasticisers or additives that could transfer into food. The development took quite a long time, as the technical profile of such products is complex, taking into consideration various benchmarks which had to be achieved. First of all, of course, the optical appearance and transparency, which has to be similar to the one offered by the conventionally used materials.
Novamont’s cling film is specially formulated to be easy to tear off without needing a serrated cutting edge, making it safer and more convenient. An intrinsic characteristic of the material is its high permeability to water vapour, helping to evaporate the condensation that forms particularly with warm food or in the fridge. This makes it ideal for preserving and protecting foodstuffs.
Another important aspect of this product is the balanced mechanical properties at very low gauge, as such films are mainly used in the gauge of 10 to 12 µ, with extremely high puncture resistance and excellent elongation values.
Moreover the product has a perfectly tuned water vapour transmission rate (WVTR) which is offering many products to be longer kept fresh in the fridge.
Mater-Bi® is the main product developed by Novamont. While providing the same strength and performance as traditional plastics, it is made of renewable resources of agricultural origin. It reduces greenhouse gas emissions and the consumption of energy and non-renewable resources, thus completing a virtuous circle: the raw materials of agricultural origin return to the earth through processes of biodegradation and composting, without releasing pollutants.
