Adhesive lamination is used to combine different substrates, such as OPET, Al foil, PE film, into multi-layer structures to achieve a range of end-use performance requirements. These end-use requirements typically include package integrity, barrier, and package appearance. In most cases the laminate's sealant layer is polyethylene-based and coextrusions are increasingly being utilized to most efficiently meet the target performance criteria.
A recent blown film study demonstrated that metallocene polyethylenes provide significant value when properly employed in coextruded lamination films.
