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."
