  1. 1. Flexible Packaging TechnologyInsight view into a market driven segment of packaging with future
  2. 2. Composite principles: laminates
  3. 3. Flexible Packaging MaterialsComponents of Flexibles • aluminium 6,35 µm - 200 µm • film 12 - 100 µm (PE, PP, PET, PA, PVC,..) • paper 20 - 300 g/m² • coatings 0,5 - 10/ 50 g/m² • polymer resin • ancillary materials (adhesives, lacquers,wax, inks,..) => these composite products are used for specific packaging systems, generic systems (pouches, lidding, blisters, laminate tubes, wrappers,..)
