GESSNER, a leading manufacturer in the filtration sector, specializes in producing wet-laid synthetic nonwovens designed to meet the specific needs of the water filtration industry. Our expertise lies in crafting thermally bonded nonwovens, which incorporate polyester (PET) or bicomponent fibers.

These high-quality nonwovens are engineered to provide superior filtration performance, ensuring clean and safe water. The integration of PET or bicomponent fibers adds robustness and longevity to our nonwovens, making them a preferred choice for durable and efficient water filtration systems.

Our commitment to quality and innovation allows us to offer reliable solutions that contribute significantly to improving water quality and safeguarding public health.




Redefining Membrane Support: The Superiority of Cranemat™ Membrane Backing Paper & Membrane Casting Substrates

Cranemat™ Membrane Backing Papers are a game-changer in the realm of Reverse Osmosis (RO) membranes. These meticulously engineered, wet laid synthetic supports provide a smooth, lay-flat surface that resists curling and eliminates membrane pin holes. Every roll undergoes rigorous testing to guarantee a high level of consistency, resulting in superior adhesion and exceptional runnability. Furthermore, extended roll lengths are available to minimize changeovers and enhance production efficiency.

Offered in both high bulk and calendered forms, our Cranemat™ products are designed to maximize physical performance characteristics. This includes tensile strength, tear strength, porosity, permeability, absorption, and laminate strength, making these products highly versatile in the marketplace. With grammage ranging from 17.5 gsm to 140 gsm (0.5 osy to 4.0 osy), and their uniform formation, these products cater to a wide array of market needs.

Discussing the Origin of Cranemat™

Historically, our Cranemat™ membrane casting substrates were supplied by Crane Nonwoven / Neenah Technical Materials. However, following the 2022 merger of SWM & Neenah to become Mativ, these materials have now become products under the GESSNER umbrella, a brand of Mativ.
