Packing method
1.Bagging: One of the most common methods for packing silicon powder is bagging. Silicon powder can be packed into various types of bags such as paper bags, plastic bags, or woven bags. The bags can then be sealed using a heat sealer or tied with a twist tie or string.
2.Drum filling: For large quantities of silicon powder, drum filling is a more suitable option. The powder is poured into a steel or plastic drum and sealed with a lid. The drums can then be stacked on pallets for easy transportation.
