PVC shield keeping meds from children
Packaging Coordinators Inc. of Philadelphia is ramping up production for a new child-safe compliance package using a patented, internal PVC shield.
``We utilize blister packaging and a printed card,'' said senior account executive Gregory Shaw. ``Children can't enter, but adults can.''
The PVC shield works off an internal spring and takes advantage of PVC's memory capability. Pulling the trigger with an index finger and thumb allows the patient to dispense the drug.
``As soon as the patient releases the trigger, it becomes child-resistant automatically again,'' he said.
PCI patented the device in early 1998 and has conducted child-resistance tests with two potential customers. The product has yet to enter the market.
Shaw said PCI is a $200 millionin-sales subsidiary of Dublin, Ohio-based Cardinal Health Inc.
Meissner researching fluoropolymer filters
Meissner Filtration Products Inc. of Camarillo, Calif., is investigating the suitability of more fluoropolymers for filter products, said sales director Charles Capron.
Meissner makes microfiltration products and equipment for the pharmaceutical industry, including polytetrafluoroethylene filter cartridges, capsules and disks for fermentor air, sterile vents and gases.
``Users are concerned with tract metal extractables, and the fluoropolymer materials have the resistance and low extractables that would ideally suit their ultrapure processing needs,'' Capron said.
Microelectronics drive the requirement to have materials with better chemical and temperature resistance, according to Capron.
``As the microcircuit-path line width gets smaller and smaller [and] geometries get smaller and smaller, they are concerned with parts-per-trillion levels of trace metals ... and particle sizes down to 0.03 micron and smaller,'' he said.
Gore broadens use of expanded PTFE
W.L. Gore & Associates Inc. of Newark, Del., is applying its expertise in expanded polytetrafluoroethylene into chemically resistant, dimensionally stable gaskets; air-operated pump diaphragms; and white fiber packing, all for chemical processing applications.
The creator of Goretex fabric even makes expanded PTFE dental floss, said Allen Guizzetti, product specialist with Gore's industrial division in Elkton, Md.
Once through Gore's proprietary processes, expanded PTFE can cope with aggressive or toxic materials requiring compliance with environmental and safety regulations.
