Drying, Curing & UV
Beyond the bond: Four considerations when choosing adhesive solutions
materials. They can help your business in a number of other ways, especially in a competitive environment where every small advantage can make a big difference. Jude Liddle, H.B. Fuller's marketing manager for EIMEA Converting Solutions, considers four key areas.

dhesive solutions have more to offer packaging manufacturers than simply bonding of
as manufacturers are using more and more recycled materials as part of their sustainability efforts. That is why H.B. Fuller provides food contact status declarations for all its adhesives, and continuously innovates to find solutions that give packaging manufacturers genuine peace of mind.
1. CONSUMER SAFETY While there may not be much adhesive in food packages like a box of breakfast cereal, any safety issues will be vitally important for manufacturers. Whenever a new raw material is introduced to the production line, whether it comes into direct contact with food products or not, it is vital that its impact is thoroughly evaluated for food safety. This way, packaging makers can feel confident consumers will be safe when packaging is used. With the migration of contaminants such as saturated hydrocarbons (including MOSH and MOAH) causing particular concern, the choice of adhesive should be considered carefully. This is particularly relevant today,

2. INCREASING EFFICIENCY Zero-defects production is the Holy Grail for all packaging manufacturers, and to achieve this, many rely on quality control technologies such as vision sensors and camera detection mechanisms integrated into the manufacturing line. These can track and adjust adhesive application in real time using UV-detection systems. However, problems can arise when using recycled boards that can contain higher levels optical brighteners used to make boards appear white. The brighteners and adhesives with a blue UV indicator, fluoresce under the same wavelength UV light, which significantly impacts the efficiency of the adhesive detection system. As a solution, detection system manufacturers introduced systems that work on the yellow/green UV wavelength. H.B. Fuller matched this change by introducing innovative UV light fluorescing adhesives, creating a range that can perform under blue or yellow-green UV wavelengths. This helps manufacturers to achieve exact adhesive placement and reduce downtime due to inaccuracy.
3. IMPROVING PRODUCT PERFORMANCE
Another benefit of our new UV fluorescing adhesives is that packaging manufacturers can be sure that their products are made exactly as they were designed, with the

adhesive applied precisely. As H.B. Fuller’s new adhesives are suitable for use on all common types of carton or corrugated boards and work with the two main wavelengths used for UV-detection, product performance can be guaranteed whatever the material or UV-detection system.
4. FINDING AN INNOVATIVE ADHESIVE PARTNER To keep ahead of adhesive packaging challenges – not to mention your competition – is hard to do in isolation. That’s why H.B. Fuller works closely with all its packaging partners, with a commitment to innovation that ensures we are always one step ahead. As a strong partner who understands the market and supply chain, H.B. Fuller can help you meet regulatory requirements and keep on top of industry developments. Everyday, the company connects its customers to its technical adhesive experts, providing support and guidance for all adhesive challenges.
