New adhesion promoting oligomers for indirect food packaing
Anna Johnson, Sartomer
Abstract:Clear regulatory guidelines exist for selecting monomers used in indirect food packaging. However oligomers can also introduce reaction by-products, residual raw materials and cross contamination that pose a migration risk. Strict quality requirements have significantly narrowed the selection of products appropriate for food packaging, in particular adhesion promoters for difficult substrates. This overview details new adhesion promoting oligomers that meet regulatory requirements and successfully promote adhesion to difficult substrates used in food packaging.
