HERMA Adhesive Offers Transparency, Durability

FILDERSTADT, GERMANY | HERMA announces 62F adhesive, said to deliver the no-label look even in challenging conditions, including extreme moisture. Company says the adhesive is endowed with excellent durability and transparency, it is well suited to critical applications in the food, cosmetic, and pharmaceutical segments. For the food industry, the adhesive has been granted unconditional approval by ISEGA

Reportedly, clear-on-clear labels can experience a framing effect when moisture causes an unsightly white haze to creep across the applied label from its edges. This problem is said to be eliminated by 62F. It was developed specifically for clear-on-clear applications in which moisture is a factor, as in the drinks industry. Even when tested by immersing in water for 96 hours, it failed to trigger any clouding, company notes. The adhesive also is said to have high initial tack and good resistance to oils and aqueous media.

Additional benefits reported by the company include the following: The grade is not subject to secondary cross-linking (unwanted hardening) in connection with multicolor printing and prolonged UV curing, thus retaining good flow behavior; to ensure that the labels preserve their qualities for their entire life, the new grade offers good resistance to light, heat, water, and aging; it is suitable for direct contact with dry, moist, and fatty foodstuffs; it delivers good print quality with all the conventional printing techniques; and it produces visually appealing, glossy, and highly transparent labels.
