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 machinesâ 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 materialsâ physical features.
A âmeasuresâ 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.
presents the breadth and scope of manufacturing flexible packaging. The subjects are essential for process and development engineers in the industry and helpful for individuals who specify and purchase its products.
