Application and use
The surface of HERMAtyvek® offers an good printing quality in conventional printing methods like e.g. flexo, screen and offset printing. We recommend special inks with a low content of solvents (< 3 %). UV inks are also possible. HERMAtyvek® requires stronger pression than paper of the same thickness. The polyethylene nonwoven is conditionally printable with thermal transfer and matrix printers.
HERMAtyvek® is highly resistant to weather and chemicals and thus suitable for outdoor applications, e.g. drum and container labelling. It is so robust and durable that it easily withstands even the toughest conditions. The properties of HERMAtyvek® remain unchanged even at extremely low temperatures. When processing/using the material in applications with high tension, the temperature should not exceed +80 °C.
HERMAtyvek® is also suitable for labels requiring a high tear resistance and durability. The PE nonwoven is 100 % recyclable. For recycling reasons, these labels are preferably used on PE surfaces.
