Components 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,..)
