Bitumen is supplied to the market in different forms. For domestic markets, bitumen tanks are usually used, while for export purposes, depending on the type of bitumen, different types of drum packaging, polybag or Bitubag are used.
Polybag or Bitubag is a new and environmentally friendly product that is used for packaging different grades of bitumen with the advantage of easy transport and handle.
To use this product, the liquid bitumen is filled at a suitable temperature (lower than the bag’s melting point and higher than bitumen’s softening temperature) into a polybag that is made of polyethylene, and after cooling, bitumen becomes hard and solid which is easier for shipping.
The packed bitumen is then put into special pools and heated to the melting point. Since the bags are melted along with liquid bitumen in this method, it prevents loss of bitumen, reduces costs, saves time and energy. It should be noted that adding polyethylene to bitumen will increase the softening point and reduce the permeability of bitumen.
Based on the consumer’s requirement, these bags are produced in smaller sizes for packing 40 to 50 kg of bitumen or in larger sizes as jumbo bags for packing 300 kg or 1000 kg.
