Next-level packaging with fine denier PET/PE nonwovens
The fine denier spunbond nonwovens from Freudenberg Performance Materials are based on flexible manufacturing processes that allow for a high degree of customization. The innovative materials can be produced from PET, PE, or PP – either in pure form or in various combinations such as PET/PE, PET/coPET, or PET/mPP – using mono- or bicomponent fibers with a titer range of 2.5 to 3 dtex. Basis weights range from 17 to 140 gsm.
Thermal bonding via flat calendering or point sealing ensures strong, reliable bonding. The result: lightweight nonwovens with excellent tensile and tear strength, along with a smooth, uniform surface.
Fully synthetic PET/PE fine denier materials are particularly well-suited for packaging applications such as desiccant bags and other moisture control products. Thanks to their outstanding heat-sealing properties, they enable fast, efficient production without the need for chemical binders or additional treatments. Freudenberg’s technology also delivers high abrasion resistance, mechanical strength, and long-term durability – making it ideal for robust, long-lasting desiccant packaging.
The ideal material for desiccant bag production
Desiccant bags are small packets filled with moisture-absorbing materials. They are commonly used to control humidity and prevent moisture damage in various products and environments, such as electronics, pharmaceuticals, apparel, shipping containers, and many more.
Our fine denier spunbond nonwovens provide the necessary mechanical properties for these applications, such as high strength and durability.
