Lintec Europe is partnering with Screen Europe at Labelexpo Europe 2019 to address ink and adhesive migration in the pharmaceutical packaging industry.
A series of independent third-party migration tests were run to assess the performance of the labelstock, during which a solution consisting of 50 percent ethanol or 3 percent acetic acid was applied to the adhesive side of the material and left in a 60 deg 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/100sq cm.
‘This is an outstanding result, when considering that the current EU regulation allowance for OML is maximum 10mg/100sq cm,’ said Soichiro Fujinaga, technical manager, Lintec Europe.
‘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,’ he added.
Lintec’s new labelstock provides improved safety for labels on plastic-molded pharmaceutical packaging. Developed primarily for use on aseptic Blow-Fill-Seal (BFS) fluid containers, vials and ampules, this labelstock significantly reduces the risk of product contamination due to the inclusion of an ultra-low migration adhesive.
Developed specifically for food and pharmaceutical packaging applications, theTruepress 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 a nitrogen purge mechanism that reduces the density of oxygen to a minimum to accelerate the curing process and minimize the risk of ink migration.
