What is Robust™ƒ

Robust™ is a dedicated fi ber blend for our products, whether BioWeb®, InFuse heatseal or Classic non-heatseal.

In our Classic and InFuse variants, this special blend makes our webs stronger, more flexible and it allows us to run more reliably and faster on current machines

For InFuse, that also means no more bleed through during heatsealing, you can now run continuously!

For our BioWeb®, the Robust™ version allows for increased mechanical stability and a wider heatseal window, which means no more lost time to adjust your equipment.

That means BioWeb® Robust™ can now be a substitute for traditional heatseal materials!

  •  Its versatility allows for easy web switches
