Paper-based adhesive seals that can be processed at production speed? Does it really work? Yes, say various pharmaceutical companies after successful tests. This solution for the tamper-proof closure of folding cartons was developed by Vioprint from Turnhout (Belgium) and perfected until it was ready for series production.<\/strong><\/p>\n

As possible first-opening protection in the packaging of pharmaceutical folding cartons<\/strong> Three variants are usually used: tamper-evident labels, so-called adhesive seals, micro-perforated tear-open tabs or a tab seal. Adhesive seals are widely used because, in contrast to tamper-evident labels, attempts to open them are immediately recognisable due to damage to the label or box.<\/p>\n

Whereas plastic was previously used for these labels (PE or PP), since last year the market has also had access to a Transparent paper-based variant<\/strong> available. This takes account of the concept of sustainability, as covering a carton with paper makes it easier to recycle and also reduces the consumption of new plastic.<\/p>

A path with high hurdles<\/strong><\/h2>\n

Statements about the \u201eGreen Deal\u201c and the more careful use of resources are omnipresent. However, the bar is set very high for practical implementation in the pharmaceutical production and packaging process. GMP requirements, qualification expenses and technical restrictions<\/strong>, coupled with high production pressure can slow down the willingness to innovate.<\/p>\n

Now it was a particular challenge for most pharmaceutical packaging companies, Properties of TE labels in line with the requirements for packaging material, dispensing systems and production stability<\/strong> to bring. It was not uncommon for the labels to be everywhere but in the desired position on the box. Even renowned label manufacturers were only able to work on product maturity in the field, and the optimisation process tried the patience of those responsible for packaging.<\/p>
