Our Nylon Wool Packs are manufactured to the Australian Wool Exchange (AWEX) Pack Standard No.3, Standards and Test Methods for Woven Wool Packs made from Multifilament Nylon Yarns (Published in Revision July 2014). This ensures that all Wool Packs are sampled, tested and carry a Certificate of Compliance, ensuring your wool is packed with the best possible materials to minimise contamination during storage and transport.
