ViviOn is the name of a new family of cyclic block copolymers (CBC), a fully hydrogenated polymer from USI Corporation, which now complements the product portfolio of the German distributor Dreyplas. In addition to high purity, all grades provide low density, high transparency, low water absorption, and a low amount of extractables. Depending on the microstructure, the mechanical properties range from rigid to soft. ViviOn can be used as a separate layer in multilayer films or as a blend partner with PE or PP. The wide range of applications extends from packaging for food and medical devices to biodiagnostics, UVC disinfection, optics, and IC manufacturing.
Thanks to their excellent barrier properties, vacuum-metallised cast films are often used in multilayer packaging. However, the comparatively low stiffness and strength of substrates made of pure PE or PP can cause cracks to form in the ultra-thin metal layer applied to them when subjected to stress. This allows oxygen and moisture to penetrate the packaging, reducing the shelf life of the contents. Blends with ViviOn 8210XT offer higher stiffness without compromising flexibility, thus reducing the risk of cracking. Depending on the application, this may also allow for the use of more material-efficient films with lower thicknesses. In addition, this CBC can be used to optimise the tear propagation resistance of the film, which is an important convenience feature for easy opening applications.
ViviOn 8210XT comes with a “Recyclability of Packaging Material” certificate issued by cyclos-HTP Institute and is approved for use in food and pharmaceutical applications.
