FLEXO Magazine : April 2014
Wednesday, April 30 17 Current Trends in the Flexible Packaging Market Ram Singhal, Flexible Packaging Association Flexible Packaging, a $27.7 Billion industry in the U.S. has evolved into packaging of choice. Each package is specifically designed to meet the varying needs of the product it holds while providing consumer conveniences, shelf appeal, extended shelf life resulting in less food waste and overall less environmental impact. The growth of flexible packaging is mainly driven by innovation and technology. The presentation will provide insights into the current trends in flexible packaging. Visual Quantification Scale for Metallic Inks in Packaging Veronika Lovell, Sun Chemical Corporation Brand owners want packages that will grab the customer’s attention and separate their products from those of their competitors. Inks that contain metallic pigments enhance a package’s appearance by the striking visual effects that they produce. As a manufacturer of specialty pigments and inks, Sun Chemical recognized the need for a process to quantitatively describe the visual effect of metallic inks often referred to as brilliance. Metallic inks were created using three types of metallic pigments and then proofed on various substrates. Samples were selected from the proofs that spanned the range of low brilliance to high brilliance. This presentation describes the development of the visual scale of brilliance, some preliminary results on correlating that scale with instrumental measurements and future work to develop an equation that accurately relates instrumental measurements and the visual judgments. The White Plate Matrix David Recchia, MacDermid Printing Solutions; Marek Skrzynski, CSW The one demand that reverse printers have is always the same “I need whiter White!” What they really mean is higher opacity, reduced mottle and pin holing. And this means absolutely smooth coverage of the white ink. Many things have been tried, most commonly a double bump of white. But a recent increase in the main component of this ink doubles the cost, to the dismay of the printers. To get the images to jump off the package the over print colors must have a smooth background which is only achieved by the white ink. Poor coverage equals poor reflectivity, and this degrades high end graphics. We seek to find a plate “Matrix”, which can be done with a single pass to achieve higher quality results. We will study all of the interactions of plate durometer, surface textures and screening patterns, stickybacks, and anilox. The quantifiable data will include opacity numbers, mottle readings, and the effects on the SID of the overprint colors. What Does the Future Hold for Flexible Packaging: Sustainability, Speed & Efficiency Grant Shouldice, Flint Group The current trends in the converted flexible packaging segment, which may include but are not limited to changes in consumer behavior, increased demand for recyclability, compostability, bio renewable content, reduction in materials and efficiency while maintaining high performance, suggests that real, tangible, product driven, sustainability solutions will be available to the flexible packaging value chain in the near future. At the same time, new developments in high-speed package printing as well as the concomitant opportunities and challenges that potentially face the players in the value added flexible packaging value chain will be discussed. Moreover, chasing sustainability and/or efficiency stories necessarily happens against a backdrop of near insatiable demand for impressive, eye catching, brand connecting graphics in this segment. A view of how to answer the question “What does the future hold for players in the value added flexible packaging value chain?” is given.
