The lamination technology is a process used to join two or more nonwoven filter media together in order to create composite materials with superior performance characteristics. This technique can be used to combine different types of materials, such as base & saturated papers, nonwovens, or miscellaneous fabrics.
By combining different filter media through lamination technology, manufacturers can create versatile products designed for optimal filtration performance while still providing enhanced durability and longevity.
GESSNER’s lamination line is capable of combining substrates such as paper, wet- or dry-laid nonwovens and films, as well as any combination of these, into a final multi-layered material.
Three bonding technologies and a finely adjustable web tension system allow us to process many light weight materials, as well as substrates with high stretch.
An ultrasonic bonding system with its dot-array pattern is used to bond up to five layers in one process step. Alternatively, the adhesive unit can spray either hotmelt adhesive or reactive hotmelts for a full-surface lamination of two layers in one process step.
