VPF’s New Deep-freeze Adhesive for Vaccines & Pharmaceuticals ApplicationsVPF launches ultra-deep-freeze adhesive 972 for extreme cooling for pharmaceutical products such as COVID-19 vaccines to guarantee their effectiveness. The adhesive can be used in connection with suitable PP substrates for temperatures down to -75°C – ideal for the labeling of vaccine doses or syringes that must be stored and transported in extremely low temperatures.

Temperature Stability Tested by Independent Institute

Highly transparent acrylate dispersion adhesive 972 has good temperature stability vigorously tested by an independent institute. Glass vaccine doses with a diameter of 30 mm, featuring labels made from 60 µ white glossy PP material (VPF 60659) and coated with 18 g/m² of the ultra-deep-freeze adhesive 972, served as the test objects.

During the series of tests, the glass vaccine doses – labeled at room temperature – were exposed to temperatures of -75°C for a period of 72 hours and then warmed to +5°C over a period of 12 hours. The test results confirmed the temperature stability of adhesive 972, which exhibited full adhesive and cohesion values. No brittleness in the adhesive or edge separation with the labels were observed.

Broad Temperature Range, Suitable for Variety of Substrates

The company specifies the temperature range of -75°C to +70°C for adhesive 972, while the labeling temperature should be above -5°C. The low-migration adhesive is equally suited to substrates made from paper as well as film. The adhesive has ISEGA approval for direct contact with dry, moist, and fatty foods with a correction factor of at least 3 (according to EU Regulation 10/2011). Adhesive 972 can also be used for labeling blood bags.

Adhesive 972 is available in a wide range of substrate and liner combinations. For high-speed labeling, PET liners with easy release systems are also available.
