Sound barrier

Perlen Packaging says it is the first company to enter the ultra-high barrier segment with PVdC based blister films with its Perlalux - Ultra Protect.

In 2006 Perlen Packaging launched of Perlalux - Tristar ultra, a PVdC based high barrier film and cost-effective alternative to PCTFE. The Swiss company’s latest offering is said to double the moisture and oxygen barrier again, using a multi-layer PVdC technology. “With Perlalux- Ultra Protect we can now provide the world’s first highly transparent PVdC film for the rapidly growing ultra-high barrier segment,” said Johannes Giessler, director sales & marketing at Perlen Packaging. “The advantage for pharmaceutical companies lies in higher product protection at improved processing and cost efficiency.”

The demands of the pharmaceutical industry on blister film barrier characteristics have increased substantially in recent years. The high barrier segment is growing at double digit percentages, driven by more complex molecular structures of new drugs, increased sales into tropical climate zones and the trend towards global distribution.

Perlalux Ultra Protect films provide high transparency and can be processed on all standard blister lines with the same parameters as standard PVdC films, without the need of additional forming aids. The symmetrical structure can be sealed on both sides to the aluminium lid foil. The barrier layers in the middle give optimum protection and highest product safety.
