2007-07-07 News Release
New oxygen barrier technology for healthcare packaging and delivery systems GLS Corporation has announced its upcoming oxygen barrier technology for healthcare packaging and delivery systems.
This ultra-clean TPE technology from GLS Corp., a global leader in the
development, manufacture, and supply of high-performance, custom-formulated
thermoplastic elastomers (TPEs), provides high oxygen barrier performance
that is up to ten times better than conventional TPEs and equivalent to
traditional thermoset butyl rubber. At the same time, it delivers the
exceptional design freedom and potential for part consolidation of thermoplastics.
Further, the ability to injection-mold TPEs streamlines manufacturing
and improves consistency by eliminating secondary operations required
with thermosets.
The new materials, which are designed to be custom-formulated, are currently available for sampling to customers. Information is available from GLS Corp. Clean Chemistry Inherent cleanliness is a key area in which GLS Corp.’s TPEs can improve upon traditional barrier packaging materials. By eliminating the use of halogens and heavy metals used in curing thermoset rubber, the new TPEs avoid the risk of leaching into the contents of medical containers or contamination of clean systems, which are increasingly used for disposable devices. In drug-contact applications, the TPEs are very inert and demonstrate an extremely low level of extractables and leachables meeting Japanese Pharmacopeia Chapter 59. Design Freedom TPEs also provide enhanced design flexibility. They can be processed using high-pressure injection molding, which helps in thin-wall parts and complex geometries, as well as extrusion and blow molding. While thermoset rubbers need reinforcing fillers that limit them in physical attributes such as clarity and density, TPE’s do not require fillers and can be reinforced using plastics. This allows them to maintain lower specific gravity and clarity/translucence. The oxygen barrier TPEs will bond to a polypropylene substrate, permitting overmolding that opens up many opportunities for part consolidation and design innovation. Consistent Quality Further, TPEs can improve the safety and consistency of the final packaging
of the product. Injection molding is a one-step process, whereas producing
thermosets requires three or four steps - compression molding, trimming,
washing, siliconizing, and sometimes manual assembly. Each step introduces
the possibility of compromised quality, which can add up to wide variations
in the finished product for packaging. No matter how many precautions
are put in place, complaints are often generated about contamination found
in the end product. Medical Packaging Jobs - Post Employment Opportunity!
