Flexible Packaging Materials 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 pa ckaging systems, generic systems
(pouches, lidding, blisters, laminate tubes, wrappe rs,..)

compete with each other.
• The films have balanced properties without
compromises.
• A large range of different properties can be
realized.
