and/or diversematerials. These techniques can be used tomerge divergentmaterials into a single structure. Examples include: - Combining paper with polymers


- Combining paper with polymers and fofoil - Combining paper with polymers and oriented films such as BOPP or BOPET


- Combining polymer layers with oriented films such as BOPP or BOPET


- Coating water based barrier or functional polymers onto BOPP or BOPET.

These processes also allow for the creation of highly asymmetrical polymeric structures where cast filmor sheet can be coated with a barrier coextrusion structure to forma highly


process does not produce additional variations in product quality. The ultimate goal is to produce flexible packaging filmthatwill run on an end user’s processwithout issue, producing high quality products for the consumer.


y. SEQUENTIAL MANUF CTURING SEQUENTIALMANUFACTURING


One of themost exciting developments in flexible packaging is the growth of sequential


manufacturing, which addresses the need to producemore complex structures. Structur e complexity i s driven by the necessity in the marketplace for improved properties. Those improved properties include:


- Improved physical, barrier, optical, seal and performance properties


- Use of thin aluminimfoils for high barrier, reducing the need for expensive resins - Elimination of solvent odours and pollution -Water-based barrier coatings


- Controlled respiration (O2 & CO2 transmission ) - Combining incompatible polymers and webs: aluminiumfoil, paper, board, and polymer films - Reduced product cost


- Combining thick, bulk layers with thinner functional layers in one step


- Application of functional coatings for new material applications, or for themodification of the surface properties.


Resourceful converters are combining the benefits of several processes into one, in order to gain amarket advantage. Newmanufacturing technologies, which sequentially combine


different and separate processes into one line, are being used fofor producing complexmulti-layer products. Some of thesemachines combine solution coating, cast film, and sheet production with the extrusion coating process.With only one line, processors can create unique, high-value composite webs consisting of several layers


asymmetric structure. Another type of sequential method is the combination of liquid coating with extrusion coating or extrusion lamination in a system. (Davis-Standardmachinery pictured.) In the end, equipmentmanufacturers an d processors alike are being challenged to go beyond the status quo in serving the flexible packagingmarket. Volume and quality will continue to drive new innovation and improved technologies. As packaging with differentmaterials and

polymers entering structures evolve


themarket, the successful converter will find novel ways to combine these properties into the ultimate flexible packagingmaterial for an application. Amachinery supplier committed to all of these processes is uniquely qualified to lead the revolution inmanufacturing techniques for packagingmaterials, both rigid and flexible.
