These innovative PLA-based wetlaid nonwovens have a variety of applications in markets such as horticulture, packaging, filtration and healthcare.

In horticulture, PLA/wood pulp wetlaid materials achieve the ideal balance between good water absorption, good rooting and degradation properties due to wood pulp on the one hand, and the high strength provided by PLA on the other. These properties are required by short-, medium- and long-term plant propagation systems, e.g. for vegetable growing, flower cultivation and forestry. The new PLA-based product line complements the current range of plant propagation wetlaid materials offered by Freudenberg, based on different component mixes including wood pulp, polypropylene, polyester and viscose.

For packaging, PLA/wood pulp wetlaids open up new sustainable opportunities by replacing plastic-based packaging, e.g. bio-based desiccant bags to replace traditional synthetic desiccant bags.

Other applications of PLA-based wetlaids include embroidery backings and interlinings for apparel, and wound dressings for the healthcare market.

The two-component mix is flexible, therefore allowing for a wide range of products to fulfill the requirements of the various applications.
