Nanotech plastic packaging could leach silver into some
types of foods and beverages

Antimicrobial packaging is being developed to extend
the shelf life and safety of foods and beverages. However, there is
concern about the transfer of potentially harmful materials, such
as silver nanoparticles, from these types of containers to
consumables. Now, researchers reporting in ACS Applied Materials
& Interfaces illustrate that silver embedded in an
antimicrobial plastic can leave the material and form nanoparticles
in foods and beverages, particularly in sweet and sugary
ones.
