Herma, the Germany-based self-adhesive materials company, is reporting that adhesives based on multi-layer technology are contributing to significant growth in the company's films segment of its adhesive materials division.
"The multi-layer concept allows us to overcome challenges that have generally arisen in the past when processing films. We have thus been able to lower substantially the risk of adhesive bleeding. Likewise, the level of contamination of the cutting dies is significantly reduced in the case of films with a multi-layer adhesive," expalins Herma's managing director, Thomas Baumgärtner. "For all label printers, these are important considerations. This has made itself felt for some time now by way of increased demand for our film label material."
Accordingly, Herma is moving forward with further expansion of its film range. The result is two new polypropylene (PP) films and a new polyolefin (PO) film which are now available.
The PP grades are glossy, biaxially-oriented films with a special surface for good printability. They are available in two versions: HERMAflex transparent (grade 833) and HERMAflex white (grade 843). Both films are designed to offer superior diecutting and dispensing properties thanks to their structure. Having undergone corona pretreatment, they achieve high print quality with all conventional printing methods. Due to their extreme adaptability, they are ideally suited for the high-end labeling of flexible containers such as those used for cosmetics, body care and household cleaning products. But they can equally be used in the food sector, for example, since they comply with the relevant EU regulations concerning contact with food.
The other new addition, Herma PO Laser (grade 801), is a white, matte, filled polyolefin film. It was specially developed for use with both black-and-white and color laser printers. In conjunction with suitable inks, its matte surface delivers high-quality printed images with all conventional printing methods. In combination with the adhesive 64Z and 64B the Herma PO Laser (grade 801) received additionally the certification BS5609 Section 2 for marine use. Herma PO Laser label sheets are particularly suitable for labeling drums or pallets.
