HERMA Develops Two PET Films for Heat-resistant and Hard-wearing Labels

Published on 2017-01-24. Author : SpecialChem


Industrial labels on circuit boards or in vehicle engine compartments must withstand exceptional temperatures. They also have to hold fast – even when applied to a moist, oily or very rough surface. In order to satisfy these specific requirements, HERMA is continuing to expand the range of films offered by its Self-adhesive Materials division. Its headquarters in Filderstadt near Stuttgart has announced the launch of two UL-certified PET films, namely silver matt XT (grade 943) and white matt XT (grade 944), both of which are targeted especially at the automotive and electrical sectors.

Extremely Durable Labels

Their special surface coating ensures supreme printability when classic methods are employed, including laser and thermal transfer. The two films are extremely rugged and thus suitable for use within a broad temperature spectrum (-50 to +140 degrees Celsius, and short-term exposure to max. +150 degrees Celsius). Their good resistance to chemicals and high tensile forces, moreover, open up a wide range of applications – and therefore bright market prospects.

Acrylate-based Permanent Adhesive

The standard coating for the new films is the HERMA adhesive 63B. It is an acrylate-based permanent adhesive that offers excellent processing parameters – a major bonus for film applications in particular. In view of its aggressive adhesive behavior, this grade is ideally suited for critical surfaces, such as rough carton, for applying labels to vials, metal containers, or drums containing chemicals, and for hot filling applications. In combination with PET, it is especially well able to withstand exposure to elevated temperatures.

A classic field of use in this context is type plates. The adhesive also offers very good water resistance and is an ideal option for applying labels to moist and cool surfaces. It resists the influence of light, heat and ageing especially well. And no matter what the machine, its die-cutting attributes are excellent.


Located in Filderstadt near Stuttgart (Germany), HERMA GmbH is a leading European specialist in self-adhesive technology. In the 2015 fiscal year the HERMA Group generated sales of around €304.5 million in its three divisions with 945 employees.
