Lintec and Screen tackle ink and adhesive migration in pharmaceutical packaging
L
intec Europe partnered with Screen Europe, a manufacturer of digital high speed inkjet printers
and label and packaging solutions, to address one of the most pressing issues in the pharmaceutical packaging industry: ink and adhesive migration. Lintec used Labelexpo Europe as an opportunity to showcase its ultra-low migration labelstock, designed to be compatible with the low migration inks used by the Screen Truepress Jet L350UV+LM label press. “Safety issues over the migration of ink and adhesive components throughout the pharmaceutical supply chain, as well as the potential health hazards they could pose to end users, are a cause for concern for brand owners and manufacturers,” explains Soichiro Fujinaga, technical manager at Lintec Europe. “For this reason, label and packaging suppliers are facing a heightened demand to deliver solutions that ensure pharmaceutical products are protected from contamination caused by inks and adhesives that are capable of migrating through the package substrate.” As a countermeasure to this issue, Lintec has designed an ultra-low migration labelstock that provides improved safety for labels on plastic-moulded pharmaceutical
process and significantly minimise the risk of ink migration. A series of independent third party
packaging. Developed primarily for use on aseptic Blow-Fill-Seal (BFS) fluid containers, vials and ampules, Lintec’s labelstock significantly reduces the risk of product contamination thanks to the inclusion of an ultra-low migration adhesive. Lintec’s ultra-low migration labelstock is
ideal for use with Screen’s Truepress Jet L350UV+LM label press. Developed specifically for food and pharmaceutical packaging applications, the Truepress Jet L350UV+LM uses Screen’s proprietary low migration inks, which are compliant with the strict safety standards of food and pharmaceutical packaging. The system features an innovative
nitrogen purge mechanism that reduces the density of oxygen to an absolute minimum to accelerate the curing
migration tests were run to assess the performance of the labelstock, during which a solution consisting of 50 per cent Ethanol or 3 per cent acetic acid was applied to the adhesive side of the material and left in a 60°C environment over a period of 10 days. The final test results revealed that, when Lintec’s ultra-low migration labelstock is combined with the Screen Truepress Jet L350UV+ LM low migration ink, the overall migration limit (OML) is of 0.6mg/100cm2. “This is an outstanding result, when considering that the current EU regulation allowance for OML is 10mg/100cm2 maximum,” says Soichiro. He concludes: “In the highly-regulated
pharmaceutical industry, label and packaging manufacturers have a responsibility to ensure their products are compliant with legislation and industry guidelines. By tackling ink migration jointly with Screen, Lintec is showing its commitment to corporate responsibility and to delivering a product that provides brand owners and end users the reassurance that they need.”

Sun Chemical SunPak FSP inks set new standard in eco-friendly food packaging
on renewable bio-based materials, has achieved a new standard in eco- friendliness through a combination of compliance and sustainability. Not only is the hugely popular inkset, which has achieved double digit sales growth across Europe each year since its launch, fully compliant with all existing food packaging legislation worldwide, but it has also been independently tested to prove the high level of its environmental sustainability. The analysis of SunPak FSP was carried
S
out by Beta Analytic, the world leader in Carbon-14 measurements since 1979, at its testing laboratory in Florida, USA. There Beta Analytic measured the ratio of radiocarbon in the inkset relative to a National Institute of Standards and Technology (NIST) modern reference standard (SRM 4990C) and the results were accredited to ISO/IEC

un Chemical has launched its flagship food packaging offset inkset, SunPak FSP, which is based
17025:2005 accreditation, the highest level of recognised quality any testing or calibration laboratory can attain. The ratio of radiocarbon was calculated as a percentage and reported as the percentage of “Biobased Carbon”, which indicates the percentage of carbon in the inkset from “natural” (plant-based) sources versus “synthetic” (petrochemical) sources. The test showed that, on average, 77 per cent of the total organic carbon in the inks in the SunPak FSP range is biobased carbon

content, with only 23 per cent being fossil carbon, of which the majority relates to pigments. Felipe Mellado, chief marketing officer and board member at Sun Chemical, comments: “For some years Sun Chemical has been working to promote sustainable solutions, such as SunPak FSP, and our ongoing approach to sustainability guides the way we develop, manufacture and distribute products, as well as how we work with our customers and suppliers. It’s therefore gratifying now to be able to provide independent evidence of the sustainable quality of SunPak FSP, one of our most popular ink ranges. Our emphasis on sustainability will continue to be fundamental to our innovation and product development and, as demonstrated by the demand for SunPak FSP, is gaining broad support from our customers.”
