Protection from corrosion: before goods are packed, materials which are liable to deterioration during transit should be properly treated with protective;highly polished metal surface are particularly subject to the dangers of rust and corrosion;It is customary to coat the surfaces thickly with a slushing oil; anti-corrosive compounds, films, wax or grease should be applied.

防腐蚀包装：在货物包装之前，对在运输过程中可能变质的材料采取适当的防护处理；抛光的金属表面很容易生锈和腐蚀。通常在表面刷上一层厚厚的抗腐蚀润滑油；防腐化合剂、薄膜、蜡、润滑油等是必用之物。用刷子、喷漆枪涂上，或在浸泡桶里加以处理；密封的容器和除湿化合物，如可用硅脂胶体；大体积液体通常装在鼓形圆桶或罐里；一些材料应该用防水纸或石蜡包纸；为了预防高危险材料，船运公司规定了包装规格；箱子应该与防水纸和布一致。
