By Dieter Schwindt, certified expert for nanotechnology and surface applications. Dry-fiber packaging is regarded as a promising approach to reducing plastic-based packaging solutions. In industrial practice, however, a central problem emerges: under humid process conditions, the materials quickly lose mechanical stability. This can lead to deformation, disruptions in machine handling and, in the worst case, downtime on filling lines. This is particularly critical in applications with high humidity or direct contact with liquids, as is common in the food and beverage industry. Existing hydrophobization solutions often reach their limits here, as they either impair forming or are not optimally scalable in economic and process terms. Challenges of dry fiber in humid process environments Dry-fiber packaging is sensitive to increased humidity and direct contact with water. Even under moderate climatic conditions, a significant reduction in mechanical stability can occur. On industrial filling lines \u2013 especially in areas with moisture ingress or direct contact with liquids \u2013 this problem is further amplified. Components can swell or lose their shape, which impairs machine handling. The consequences are disruptions on the filling line, increased reject rates and potential downtime. In practice, such effects frequently lead to additional cleaning cycles and a restart of the production line \u2013 a clear economic disadvantage. Limits of existing solutions Conventional hydrophobization methods such as AKD can only be used to a limited extent with dry fiber. A key approach in dry-fiber processing is instead to leave the fibers unaffected during forming, so that processes such as stretching and drawing can be carried out completely and without restrictions. The functional barrier is therefore deliberately applied only after forming. In many cases, an additional external coating is thus required. Alternative approaches \u2013 such as the use of MFC for hydrophobization \u2013 are known, but are often associated with higher costs and reduced process speed. An industrially scalable solution with a stable barrier effect and good processability therefore remains a challenge. SiOPack\u00ae as a solution approach With SiOPack\u00ae technology, a coating system is available that enables a stable water barrier on fiber-based materials without affecting the forming process. The aim is to reduce moisture absorption while improving the mechanical stability of components during further processing. The results to date show that significant improvements can be achieved through the use of suitable barriers: reduced moisture absorption improved dimensional stability of dry-fiber components more stable machine handling during further processing lower reject rates increased process reliability on filling lines Test results under practical conditions The results obtained show an improvement in storage and process stability. Storage times of more than 150 days could be achieved under non-climate-controlled conditions without significant losses in top-load stability. The results indicate potential for future applications in the field of hot beverages and other moisture-sensitive packaging applications.
