Herma has launched two new label self-adhesive materials with transparent PP film that combines economical clear-on-clear proper-ties with certified wash-off qualities.

In both cases, a transparent PP film combines particularly economical clear-on-clear properties with certified wash-off qualities – available in the net width range with short delivery times. The basis for the two new self-adhesive materials is the innovative, permanent multi-layer adhesive 72Hpw. It provides both high transparency for standard applications and certified wash-off properties, the company reported.

“The 72Hpw adhesive we have developed has once again proven to be a perfect all-rounder for film applications. Its excellent permanent adhesive properties are impressive even in humid conditions, such as those sometimes encountered in beverage filling,” said Hendrik Kehl, product manager at Herma. “Its special formulation ensures both wash-off properties and transparency. This adhesive is further proof of how multi-layer technology can be used to combine different and sometimes contradictory properties in a practical way.”

For the clear-on-clear application, this adhesive is combined with HER-MA PP transparent super tc film (type 886) and two different PET release liners. The latter are available in thicknesses of 30µm and 23µm. The new self-adhesive materials thus cover virtually all processing requirements and offer high-speed dispensing options. In label production itself, good print quality can be achieved with all conventional printing processes. Both new self-adhesive materials are ideally suited for labeling cosmetic products, household cleaners, etc., as well as for applications where weather and chemical resistance are required, the company said.
