Baumer hhs is launching an advanced hot melt system for applying pressure-sensitive adhesives to corrugated board and cardboard. It can be used to produce e-commerce cartons and shipping packaging with pressure-sensitive adhesive closures that increase shipping security in online retail.
The Covid 19 pandemic has driven up demand for e-commerce cartons and other shipping packaging with pressure-sensitive adhesive closures worldwide. The packaging is typically sealed with adhesive strips that are Applied with hot melt systems and then covered with silicone strips become. The demands of the e-commerce market on the application quality of pressure-sensitive adhesives are constantly increasing.
„Today, adhesive strip application systems are expected to apply perfect, uniform layer thicknesses and cover them precisely with silicone strips, even with large application quantities and high production speeds. The more homogeneous the contact surfaces, the more reliable and stable the shipping packaging is sealed. At the same time Homogeneous contact surfaces facilitate the work of employees in the dispatch department. You no longer need to brush your hand over the packaging to seal it tightly. Baumer hhs is launching an advanced hot melt system on the market that is characterised by stable application quality and high melting performance.“ Andreas Schneiders, Business Development Manager Corrugated at Baumer hhs.
One highlight is the application head specially developed for these applications. In combination with a new volume flow control, it guarantees very good performance values at the highest production speeds. With the correct settings and adequate ambient conditions, it can be used to apply adhesive weights of up to 500 g/m2 realise. The uniform contact surfaces that are created the basis for stable bonding. Sharp tear-off edges and minimised tailing also ensure that no pressure-sensitive adhesive is carried over into other areas of the packaging or even into machines. There is also flexibility in terms of the pressure-sensitive adhesives that can be used: The new application head processes a wide range of different adhesives with varying degrees of viscosity.
Hot melt system from Baumer hhs as a complete solution
The system is a complete solution including an energy-efficient melter, high-performance application head, control unit, product guide and robust holder with fine adjustment. This means that packaging manufacturers get a turnkey system for applying pressure-sensitive adhesives to corrugated board and cardboard from a single source. When it comes to silicone strip dispensers, the company basically gives its customers a free choice. The hot melt system is integrated into the depth with the silicone strip dispenser of the Baumer hhsco-operation partner Enpro, via which it can also be controlled. Otherwise, it can be integrated into all standard Baumer hhs control systems.
The durable hot melt system can be flexibly configured. Various nozzles are available for the application head. The masks can be adapted to individual requirements in order to realise different application patterns depending on the packaging to be produced.
