What you do n’t see are the silent ingredients that have ooze into your nutrient during repositing , namely the chemicals that are contained in the promotional material that comes into tangency with your food . In fact , the Food Packaging Forum , a Swiss nonprofit , has linked 175 toxic substances to New packaging materials such as atomic number 13 foil , cans and plastic wrap [ root : Wagner ] . Formaldehyde , for case , is a cognise carcinogen , yet modest levels of the substance are legally set aside in plastic bottles for carbonated beverages . Other nutrient packaging turn back bisphenol A , tributylin , triclosan and phthalates , which are know to stamp down fertility rate and cause hormonal disruption .
How much harm exposure to these chemicals campaign over a lifetime — or to the solid food itself — is still unclear , but scientists are taking a closer spirit at whether food packaging can really better the nutritionary war paint of the nutrient it has touch with . Entersmart packaging . This new generation of packaging could necessitate all sorts of innovations , such as milk carton inside with an enzyme that would eliminate milk sugar or packaging that keep food for thought decay by killing specific microorganisms . Food encased in antimicrobic smart promotional material might need fewer additives , and it might taste good thanks to the addition of certain polymers [ source : Waldman ] .

While this may vocalise like a blank - historic period answer best reserved for a sci - fi movie , it ’s already happening . Nanosilver(silver nanoparticles that stamp down microbic increase ) is in baby feeding bottle and cutting boards . More to the point , it ’s authorized for function in pliant food container in the United States ( although it ’s blackball in the European Union ) . But despite its use , nanosilver is n’t well understood , nor are its possible effect on food , nutriment and the human dead body [ origin : Seltenrich ] .
