Flexible packaging such as stand-up pouches is becoming increasingly important. These packages consist of several layers of film to ensure that the desired requirements such as good mechanical stability, good printability or light impermeability can be met. It is only due to adhesives that these various films can be combined to form a multi-layer packaging. Hence, they play a decisive role when it comes to developing and manufacturing packagings.
As a leading supplier of adhesive raw materials BASF offers the packaging industry new possibilities and opportunities with its aqueous dispersions and additives. Water-based adhesives are an environmentally friendly and efficient alternative to solvent-based and solvent-free adhesives that have been used up to now.
Our dispersions are free from toxic substances and are approved for direct food contact. In addition, they allow the immediate further processing of laminates. Due to this fact, converters can reduce the time span between incoming orders and delivery to one day, significantly decrease their stock and focus on their core competences. A recently published article in the magazine PackagingFilms summarizes the benefits and characteristics of our water-based adhesives. With our additives, light protection and barrier properties can be precisely adjusted. Moreover, degradative reactions can be reduced in high-temperature processes.
Apart from intensive technical support, we offer our customers the opportunity to benefit from our innovative coating center. We have coating/laminating machines both at laboratory as well as at pilot-scale level, which are both specially suited for packaging applications. There we develop and test dispersions specifically for our customers.
New study proves benefits of water-based adhesives
A recent Eco-Efficiency Analysis conducted by BASF and Comexi Group demonstrates the benefits of our water-based adhesives in comparison with other systems, in particular solvent-based products. Due to fewer chemical inputs – and therefore a lower carbon footprint –, our aqueous systems prove to be more environmentally compatible. They also provide maximum cost-efficiency, as energy costs are reduced and there are no additional costs for the solvent. Moreover, thanks to a high initial bonding strength, production procedures are accelerated – which results in more flexibility to respond to customer demand. Finally, as our water-based adhesives contain neither organic solvents nor aromatic isocyanates, production risks are reduced to a minimum and health and safety in the workplace is improved.
The BASF Eco-Efficiency methodology was most recently validated by NSF International, and the results of the study were critically reviewed and validated by a panel of independent experts led by TÜV Rheinland.
Axel Weiss, Head of Marketing Dispersions for Industrial Adhesives Europe at BASF, shows the certificate of TÜV Rheinland. The testing institute validated the results of the eco-efficiency analysis.
