Coating & Laminating
A Silkoseal Reaction D
ruckfarben, a Flint Group Company, underwent a full review of its Silkoseal Sealer range. Druckfarben acquired the Shackell Edwards brand and started the manufacture of this sealer product in 1995. Over this period, the use of oil- based over-print varnishes (OPV) for offset printing has grown significantly. There are dual benefits of using oil-based OPV. Firstly, they can enhance the appearance of the printed item by
creating an overall, or spot, matte or gloss varnish effect. Secondly, the use of an oil-based varnish will also help protect the printed product during creasing, cutting, bindery processes and ultimately extend its lifespan. Silkoseal is one of Europe’s leading brands of oil
based, over-print varnish and has maintained this position through development and refinements in line with modern printing press requirements. Grant Penfield, EMEA business director
sheetfed commercial, says, “In recognition of the need to produce faster print results, selected Silkoseal varnishes have been specifically formulated to help improve ‘work and turn’ through enhanced drying speeds and improved rub resistance. We have taken this opportunity to review the range of finishes and formulations, which now cover everything from clear, matt, gloss, quickset, hard dry and laser sealers.” Druckfarben customer reaction group, based in Poole, Dorset, has been using Silkoseal over-print
varnishes for five years. Andy Ostler, director, says, “We purchase our Silkoseal from Druckfarben: the quickset sealer is a versatile all-purpose sealer that dries quickly with good rub resistance and is ideal if a job is to be perfected or converted quickly.” In May, Druckfarben brought together the
portfolio and transformed it into a new A4 guide for quick and easy reference. The guide contains a full list of sealer types and a range overview.

Demo-linedelivers encouraging results E
xactly a year has passed since SML put a FlexPack 1800 extrusion coating line into operation, for the purpose of extensive testing, at its Lenzing headquarters. During the past year, 35 trial runs were completed for customers and raw material manufacturers from around the globe. These trials consisted of product modifications, new product developments and direct comparisons of performance with the existing plant capacity. Individual testing with the various clients demonstrated the diverse range of applications for extrusion coating and laminating. Moreover, trials reflected the divergent demands made upon a production line when manufacturing food-
packaging materials, technical laminates, building products, and hygiene and medical articles. Fortunately, due to the modular and flexible design of the FlexPack system, virtually every test could be completed using the original equipment; although it should be added that certain products posed fresh challenges, which required additional innovation. Nevertheless, solutions were repeatedly found for the customer and over time this led to useful process technology functions, which further enhanced line flexibility. The DoubleCoat process, for which a
patent is pending, met with a particularly positive customer response. Trial runs were held in relation to the manufacture of new
hygiene, medical and building products, during which a special focus was placed on a reduction in the thickness of the functional layer and improved composite adhesion. The results achieved largely exceeded customer expectations and as opposed to the products currently on the market, surpassed the stipulated values several times over. The availability of the test line has also had
an extremely positive effect on SML sales in the extrusion coating segment. Its performance convinced numerous customers of the advantages of this type of plant. Consequently, during the last year several new orders for coating lines were concluded and more projects are close to finalisation.
