Austria-based flexible packaging maker Constantia Flexibles has introduced a new laminate, PERPETUA ALTA, based on polypropylene (PP) with enhanced chemical resistance for pharmaceutical products.
The firm’s latest offering combines “Design for Recycling” guidelines with high chemical resistance against aggressive liquid or gel formulations.
The mono-polymer solution replaces the multi-material packaging for chemically aggressive products such as pharmaceutical liquid and gel compositions.
German Institute cyclos-HTP has certified the material recovery of the laminate up to 96%, depending on the final material configuration.
Constantia Flexibles Technical Organization & Innovation Pharma vice president Joerg Adrian said: “We highlight the need for more sustainable packaging in the pharmaceutical packaging business with our innovation PERPETUA ALTA.
“It was our goal to achieve a high-performance ready-to-be-recycled solution. Although designed for highly aggressive pharma products, PERPETUA ALTA may also find applications in other market segments requiring high chemical resistance, e.g., food applications.”
According to the firm, PERPETUA ALTA is comparable to multi-material laminates incorporating aluminium that meets HCR standards because it can endure various substances under accelerated ageing circumstances, such as a hydro-alcoholic gel.
The advanced laminate provides superior product protection from oxygen, water vapour, and light at a lower weight and higher yield than a traditional laminate solution.
The laminate-based packaging format is a drop-in replacement for including stick packs, sachets, and strip packs.
Constantia Flexibles said that the production of the new laminate does not require the replacement of the packaging machines.
In May last year, the company agreed to acquire Turkey-based packaging producer Propak for an undisclosed sum.
