Rosin products are packed in drums made from 0.4mm galvanized sheet irons. Such sheet irons mostly come from importation. They have 17 layers of galvanization with a total thickness of 0.4mm. Domestic sheet irons are sometimes employed with the questions such as less galvanization layers that is easily oxidized and thinner in thickness (0.35mm) and less stiffness.Each drum of rosin usually has a net weight of 225KG, a gross weight of 233KG. The drum itself weighs 8KG. (0.4mm)
      When packing, each drum should be full, do not add broken pieces. The tin should be covered tightly. It should be put upside down to avoid direct sun shot and high temperature. This can also let the rosin softened and down to push air out so as to reduce contact with oxygen. Rosin should not be piled in the open air because of high temperature and quick oxidization. It should not be stored too long; it should be used 1-2 years after producing.   
      Some purchasers require the rosin be packed by paper and then put into knitted bags. Using this method, the rosin is easy to break; but it's of low cost. During storage and shipment, heat and fire should be avoided; heavy impact, which may cause the tin to deform and break, should also be avoided.

      Turpentine is usually contained in drums made from 2mm galvanized sheet irons. The average net weight of each drum is 175KG, and gross weight 197KG. The drum itself weighs 22KG. (2mm in thickness)
      After putting into the drum for some time, turpentine will become turbid and there will be white particles deposition separated out, covering the bottom and make the nearby turpentine to be milk white and opaque. This is because turpentine reacts with zinc oxide, zinc resinate and chloride under the presence of water and air. It is oxidized and polymerized, generating suspended substance that combines with zincic salt to become white particles depositing to the drum bottom. To avoid becoming turbid, newly produced turpentine should be standing for 7-10 days in the storage. Before packing, it should be filtrated by salt to remove residual water in it.
       The drum for turpentine should better be coated a thin film of Teflon for protection.
In storage and shipment, heat and fire should be avoided; the storage place should be shaded and cool. In shipment, the cover of the drum should be screwed tightly to prevent water from entering.
