Perfecseal's high-barrier PVC-free blister-forming web, PerfecForm SkyBlue, is based on polyolefin chemistry, and its new high-barrier flow-wrap specification, PerfecPharm P232, is capable of achieving hermetic seals at the maximum speed capabilities of the top flow-wrap equipment.
Perfecseal has introduced a new high-barrier, PVC-free, blister-forming web, PerfecForm SkyBlue, designed to be cost effective and provide barrier properties to protect all but the highest barrier requirement product applications. This high-barrier blister film is based on polyolefin chemistry, rather than the chlorine chemistry used to produce PVC forming webs.
Unlike other barrier blister films, PerfecForm SkyBlue is manufactured via a co-extrusion process as a symmetrical structure. The thickness of the barrier layer, which is sandwiched between co-polyester, determines the overall barrier performance.
Perfecseal has also introduced a new high-barrier flow-wrap specification, PerfecPharm P232, which is capable of achieving hermetic seals at the maximum speed capabilities of the top flow-wrap equipment. “Perfecseal evaluated this product on high-speed Bosch flow-wrap equipment to assure this product would meet the desired performance level demanded by the healthcare market,” states Georgia Mohr, pharmaceutical director of Perfecseal, in a press release. “The P232 flow wrap material offers a large sealing window (140°C–200°C) and the potential to run at lower temperatures than traditional materials, yet seals hermetically at speeds exceeding 300 ppm.” Once again, Perfecseal delivers packaging solutions based on material science expertise.
