Hostaphan® RHB Polyester Film |
| The coextruded PET film for highest barrier effect after metallization or coating with ceramic barrier layers. Hostaphan RHB is a biaxally oriented, coexturded film, made of Polyethyleneterephthalate (PET) with a structure optimized to offer previously unattainable barriers against oxygen, water vapor and other gases as well as aromatic substances after vacuum coating with aluminum, AL203 or SiOx. |
