Extreva media is developed for use in all HP Indigo presses. Reported to offer an improved shelf life, a dual-layer coating system, and the ability to order specific quantities. The line will include GE Lexan films, rigid vinyl, PETG, and a selection of other popular media.
Resin Leads to Strength

Aliphatic TPU PU resin is suited for extrusion into film and sheet for use as a bonding adhesive between layers of glass, PC, or other dissimilar substrates. Company says the created composite is used in applications in which extremely high strength and impact resistance is required. Can be produced in UV-resistant polyester and polyether grades.
Layer Adds Barrier to Films

FlexoHybar CO barrier films from Flexopack (Koropi, Greece) use a Topas cyclic olefin copolymer layer to gain high modulus, transparency, and improved moisture barrier, says company. This layer eliminates the need to build stiffness by laminating oriented films to the barrier-coex film, reducing production steps and saving money. Topas also is said to provide excellent resistance to abuse and punctures.
