The products obtained from plastic polymers have very long degradation times, they pollute water and soil, resulting toxic to animal species and humans. Their replacement, in favor of bio-sustainable and less impactful products, is one of the main objectives of our century. The biocompatible film was born as a substitute for the plastic films (generally in polypropylene or polyethylene) used in numerous agro-industrial and zootechnical applications, such as for example the covering of silage or mulching.
What is proposed is therefore a valid, bio-sustainable and less impactful alternative to plastic sheeting.
The biocompatible coverage is obtained from a natural film-forming agent, such as proteins or polysaccharides, and reinforced using natural fibers, such as grass or shavings. The mechanical characteristics of the coverage can easily be modified, for example by adding natural plasticizing substances, so as to provide the optimal characteristics according to the intended use. The product can be formed directly on the product to be preserved or made in the desired shape, so as to be used later. The fabric produced is able to resist for times suitable for agro-industrial applications and is able to resist shocks.
The main advantage of the coverage is that it does not pollute the ground when damaged or left to operate for a long time. Not infrequently, in fact, the continuous reuse of plastic sheeting, not least particularly adverse weather conditions, end up damaging it, with the consequent release of microplastics into the environment. Microplastics, in addition to being pollutants, are ingested by animals with damages that inevitably end up affecting humans as well. Another advantage of the coverage, compared to the common plastic sheets on the market, is precisely that it is not toxic to animals.
