These Wool Packs are made from high density polyethylene (HDPE) woven fabric. Manufactured as a general waste bag, this grade of Wool Pack may contain loose fibres that can cause some contamination of the wool in the bale and consequently is not recommended for use in the wool packaging industry. However, as an economical alternative these are ideal for numerous other uses such as recycling, waste collection, garden refuse, packing rags, bulk sand, bulk building materials and other general uses.
