6 Reasons why for a 5 ply Typical choice for opening/developing markets Intrinsic flexibily of production : Barrier no Barrier Downgauging and cost reduction vs/ 3 ply coex It can be a 3 extruders or a 5 extruder configuration Makes possible a symmetric barrier film production No curling on PA/PE structures Workhorse for barrier substrates in flexible packaging 6

9 Reasons why for a 7 ply Downauge a comparable 5 layers barrier film Provide for more and thinner barrier layers Provide for dual barrier feature Protect moisture sensitive EVOH with PA Optimise slip/antiblock use Bury some off-grade into structural layers 9

11 Reasons why for a 9 ply Softer barrier film than 5 or 7 ply Provide for more and thinner barrier layers Optimised sealant/skin layers Provide for dual/triple barrier feature Extremely heavy layer possibility Protect moisture sensitive EVOH with PA Improved cold strength Ready-made alternative to laminated products Equipment destinated to experienced users 11

40 Coextrusion requires a Threeways view 1- Specialty Films sales serving 5 key industries Food & Beverage PET food Converter (external) Industrial Medical/Pharmaceutical 2 - Distribution sales with focus on the following National Distribution Regional Distribution Niche Market Distribution 3 Vertical Integration for internal converting applications 40
41 Some useful hints to be recognized as a premier supplier of Flexible Packaging Solutions to various industries and markets Develop an outstanding partnership/cooperation with major key accounts. Provide for a dedicated account team works with the clients and their facilities to ensure a thorough understanding of their needs and expectations. Then you can review the specific flexible packaging applications to ensure you can recommend the right product for the application. In many cases you could be in the position are to offer cost saving alternative products by offering value added products. Your strategic objective is to provide their clients with the product they want! Some of the benefits the clients may receive from the above approach :. Significant packaging cost savings Decreased inventories and costly floor space Utilization of a stronger and better performing material that greatly outperforms previous products Reduced production costs due to better machinability of value-added products 41
