Efficiently and profitably delivering quality flexible packaging to the marketplace requires designing and manufacturing products that are both "fit-to-use" and "fit-to-make". The engineering function in a flexible packaging enterprise must attend to these dual design challenges. _Flexible Packaging_ discusses the basic processes used to manufacture flexible packaging products, including rotogravure printing, flexographic printing, adhesive lamination, extrusion lamination/coating; and finishing/slitting. These processes are then related to the machines used to practice them, emphasising the basics of machines’ control systems , and options to minimize wasted time and materials between production jobs. Raw materials are also considered, including the three basic forms: _Rollstock_ (paper, foil, plastic films); _Resin_; and _Wets_ (inks, varnishes, primers). Guidance is provided on both material selection, and on adding value through enhancement or modification of the materials’ physical features. A ‘measures’ section covers both primary material features – such as tensile, elongation, modulus and elastic and plastic regions – and secondary quality characteristics such as seal and bond strengths, coefficient of friction, oxygen barrier and moisture vapour barrier. * Helps engineers improve existing raw material selection and manufacturing processes for manufacturing functional flexible packaging materials. * Covers all aspects of delivering high value packaging to the customer – from the raw materials, to the methods of processing them, the machines used to do it, and the measures required to gauge the characteristics of the product. * Helps engineers to minimize waste and unproductive time in production.
