COC Sparkles as Barrier Layer in Coex Sheet.Coextruded rigid films for thermoforming in which cyclic olefin copolymer Cyclic Olefin Copolymer (COC) is an amorphous polymer made by several polymer manufacturers. COC is a relatively new class of polymers when compared to polypropylene and polyethylene. (COC See chip on chip. ) is used as the core layer between PP skins have been launched by Tekni-Plex Inc., Somerville, N.J. A first in North America, these Novinex products are trilayer films 10 to 20 mils thick. For moisture-barrier applications, they are alternatives to PVC PVC: see polyvinyl chloride.

Potential uses include blister packs, trays, lids, and stand-up stand·up or stand-up adj. 1. Standing erect; upright: a standup collar. 2.

Novinex films form easily and at speeds comparable to vinyl-based films, says Michael Cain, Tekni-Plex product-development manager. He also says the COC layer (unlike other barrier materials) remains continuous during forming, which gives improved product protection. The Topas COC core resin comes from Ticona in Summit, N.J. Besides moisture barrier, it provides clarity, strength, and stiffness (the last is critical for stand-up pouches). |
