Wool is a natural, non-toxic material, free from harmful chemicals or synthetic compounds that could leach into sensitive contents. When processed for packaging, it is cleaned and treated with food-safe standards, making it ideal for direct or indirect contact with pharmaceuticals, dairy, meats, fresh produce, and other consumables. Its safety profile reduces the risk of product contamination or regulatory issues.
