H.B. Fuller, a provider of adhesives and sealants, has introduced Advantra extreme cold resistant adhesives to cater to the pharmaceutical industry.
The new adhesive grades come with hot melt advanced technology developed for extreme cold storage of vaccines and medication packaging.
These adhesives can provide a secure bond at -70 C with tamper-evident fibre tear.
Appropriate packaging is required to securely preserve and transport pharmaceutical products, including vaccines and medication, right from the time they are filled to until they reach a patient.
According to H.B.Fuller, adhesives play an important role in packaging performance, particularly to meet the stringent requirements of storage.
The company is offering readily available extreme cold resistant adhesive grades with Advantra 9280 EU and Advantra BOLD 948.
Designed for tough surfaces and conditions such as high-speed pharmaceutical packaging lines without counterpressure, these adhesive grades are commercially offered in Europe, India, Middle East, and Africa (EIMEA), and with equivalent performance grades being available across the world.
Series of tests were conducted by the adhesive innovator with various industry-standard pharmaceutical packaging carton samples.
The tests were done at H.B. Fuller’s Lüneburg Adhesive Academy in Germany.
The new adhesives are claimed to have been formulated for better adhesion on GC1 and GC2 type carton boards.
Following testing, the Advantra adhesives are claimed to have demonstrated tamper-evident fibre tear on pharmaceutical packaging and confirmed fibre tear after seven days storage at -70 C and after reconditioning at refrigerator temperatures of 4 C (39 F) following comprehensive testing.
