Einar® anti-stat solutions for impact copolymer polypropylene (PP) • Einar® 411 is a superior food-grade anti-stat for impact copolymer PP • Einar® 411 offers excellent performance at low humidity and across a wide range of applications Application background . Impact copolymer PP is used in many different food and non-food packaging applications where an attractive appearance toward consumers are important. An appealing and dust-free packaging is secured by the use of efficient migratory anti-stats that are able to build a concentration on the packaging surface that form a conductive layer. This will enable dissipation of static charges whereby dust and other fine particles will not be attracted or settle on the packaging. Impact copolymer PP is the preferred packaging material for a very wide range of both food and non-food products because it offers excellent protection. The polymer has high impact strength at low temperatures and has good barrier properties for protection of packaged goods. The inherent nature of the polymer also provides challenges for migratory anti-stats. They need to be optimized for the polymer in order to guarantee an attractive and clean appearance.
