Herma introduces new multi-layer products

Herma will introduce two multi-layer products based on its HERMAperfect technology, from March 1 2012.

The product lines HERMAperfectCut (with the 62Xpc adhesive) and HERMAperfectTack (62Gpt) will replace the current lines based on the 62X and 62G adhesives, reportedly offering customers significant product enhancements. For the time being, HERMAperfectStick (62Dps) will not be affected by the change.

Herma managing director Dr Thomas Baumgärtner said, ‘We have consistently promised to use the HERMAperfect multi-layer technology to offer all-purpose products with appreciable value-added and the customary service, but without giving rise to extra costs for our customers. We are now living up to that promise.‘

With HERMAperfectCut, film label producers no longer have to make a choice between good adhesive properties and high converting quality because the dispersion adhesive is applied in conjunction with a new, specially developed second layer. This means less bleeding of the adhesive takes place during die-cutting and converting. It ensures less contamination of the die-cutters, improves convertibility and die-cutting results, thus enhancing machine performance. The improved converting properties have been achieved, without any reduction in either peel adhesion or tack.

In view of its additional second layer, HERMAperfectTack offers high tack even in difficult ambient conditions, such as moisture and low temperatures. The 62Gpt adhesive is based on a dispersion adhesive and offers excellent converting properties – unlike rubber-based hotmelt PSAs. In addition, the adhesive layer with 62Gpt is suitable for direct contact with dry, moist and, fatty foodstuffs according to trials carried out by the German test institute ISEGA. Thanks to their high tack, labels incorporating HERMAperfectTack are suitable for the blow-on process used for labelng at low temperatures. In such applications, labels are often attached to cool and moist substrates contactlessly by air, 62Gpt ensures extremely precise application without slippage. The benefits of the adhesive come to the fore in particular when high tack is essential because of different types of board, or when labels are being applied over edges. Since the adhesive allows labels to be applied even at minus 10 degrees Celsius, it is suitable for goods that are to be shipped at a constant low temperature throughout the entire (temperature-controlled) supply chain.

Label printers will now have access to a large range of pre-slit rolls in defined standard widths, even when specifying HERMAperfect products. Herma customers can call off supplies from the pre-slit range for immediate shipping, with a delivery time of 24 hours in most countries. The HERMAperfect products have also been integrated in the net width range. Customers can obtain pre-slit rolls in any width, exactly cut and without any charge for off-cuts.
