Herma’s Self-Adhesive Materials division has launched HERMAtherm top M (grade 912), a white thermal paper specifically designed to give improved results in the weight/price labelling of pre-packed foods that are subject to the effects of humidity.
According to the Germany-based self-adhesive technology specialist, HERMAtherm top M is enhanced by a protective coating that gives very good results both when labels are being applied to humid surfaces, as well as when subsequently exposed to the effects of humidity.
The BPA-free material is advantageous in any application in which thermal labels made from smudge-proof, solvent- and grease-resistant paper are required.
“Consumers are increasingly choosing to buy their fresh meat, sausage and cheese products in pre-packed form,” Herma says.
“A major priority for the food industry and retail sector is therefore to have reliable, high-quality label materials that lend themselves well to initial pre-printing and subsequent overprinting with the variable weight and/or price data.”
This poses a particular challenge, the company says, because of the demanding ambient conditions which often prevail when such labels are being applied and printed with variable data.
HERMAtherm top M has “superior whiteness” compared to its predecessor material HERMAtherm top R (grade 918), and its improved thermal printability make it highly suitable for EAN and UPC codes.
The new material is said to be less susceptible to scratching, thereby aiding barcode reading accuracy.
“An important factor for pre-printing is the smooth surface of HERMAtherm top M, which also delivers improved print quality with all the classic printing methods,” Herma says.
Print speeds of up to 200 mm/s are possible with direct thermal printing, and label printers can benefit from all the familiar net width services right from the start.
