COC Composite Packaging Reduces Water Vapor Transmission Rate

Tekni-Plex, a US plastic film factory, used COC Topas and chlorofluoroethylene (PCTFE) materials for the first time in the production of high-barrier blister-type composite packaging films, resulting in water vapor transmission rate of blister packages. Greatly reduced. The application of this new type of blister packaging film Tekniflex is pharmaceutical packaging.

Compared with the general PVC and PVDC (polyvinylidene chloride) barrier blister packaging films, the development of cycloolefin copolymers in blister packaging applications has been successful, not only the water vapor transmission rate of the material is very low, but also the thickness It can be thinned and its rigidity increased. Among them, the thickness of COC ranges from 200 to 350 um, and the thickness of PCTFE ranges from 10 to 100 um.
