A combination of Tekniflex PCTFE blister and CSP Technologies™ Activ-Strip® polyethylene dessicant creates the first transparent thermoformed PCTFE blister exceeding the headspace protective properties of aluminum packaging.

SOMERVILLE, NJ: Tekni-Films, a Tekni-Plex Company, now offers the TEKNIFLEX® Modified Atmosphere Blister (MAB), the first transparent thermoformed PCTFE blister that takes the proven barrier properties of two and three-layer PCTFE laminates beyond those of cold formed foil. The new TEKNIFLEX MAB incorporates one or more CSP Technologies’ Activ-Strips polyethylene dessicant strips into the rib design of the blister card, linking every cavity with the dessicant.

The patented technology makes it possible to significantly reduce headspace moisture content to extend the shelf life of products. The Activ-Strip does not come in contact with the product, it is dust free, and complies with all relevant EU and US pharmaceutical and food regulations. Performance can be tailored by using different sheet thicknesses, sheet sizes (surface area) and dessicants (molecular sieve or silica gel).

When tested with TEKNIFLEX VA7200, one CSP Activ-Strip maintains the headspace dry for approximately two months at ICH accelerated stability conditions (40º C/75% RH). At three months, the same blister card with two CSP Activ-Strips maintains the headspace below 10% RH. Three CSP Activ-Strips can guarantee a dry headspace for two years at ICH long-term storage conditions (25º C/65%RH).
