产品在运输周转过程中，由于气候、机械、生物和化学等因素的影响会受到一定程度的损坏。适当的包装可以保护产品不受这些因素的影响，同时，包装可以防止或减少货物的丢失和损坏。因此，保护产品是产品包装更基本的作用。包装防护主要有：防雨、防潮、防霉、防锈、防海水浸蚀、防大气侵蚀、防尘、防震、局部、防护等方式。
In the process of transportation turnover, the products will be damaged to a certain extent due to the influence of climatic, mechanical, biological and chemical factors. Proper packaging can protect products from these factors, and at the same time, packaging can prevent or reduce the loss and damage of goods. Therefore, product protection is the most basic function of product packaging. The main methods of anti-corrosion, anti-corrosion, anti-corrosion, anti-corrosion, anti-corrosion, anti-corrosion, anti-corrosion, anti-corrosion, anti-corrosion, anti-corrosion, anti-corrosion, anti-corrosion, anti-corrosion, anti-corrosion, anti-corrosion, anti-corrosion, anti-corrosion, anti-corrosion, anti-corrosion, anti-corrosion, anti-corrosion.
1.防潮包装：货物进行防潮包装时，应采取必要的防潮措施。例如在防潮材料密封的容器内加适量的干燥剂等。
1. Moisture proof packaging: necessary moisture-proof measures shall be taken when the goods are packed with moisture-proof materials. For example, add appropriate amount of desiccant in the container sealed with moisture-proof materials.
2.防震包装：防震包装应根据货物的特点采用不同的防震形式。
2. Shockproof packing: the shockproof packing should adopt different shockproof forms according to the characteristics of the goods.
3.防雨包装：货物进行防雨包装时，应在封闭内采取必要的防雨措施。
3. Rain proof packing: when the goods are packed with rain proof, necessary rain proof measures shall be taken in the closed area.
木箱内衬以防水材料，货物外部罩盖和包装箱顶盖采用双层防水材料结构等。遮盖货物所用的塑料薄膜一般不采用聚氯乙烯。如若使用应加强措施，使其不与产品漆层直接接触。在有内包装箱的复箱式包装中(如精密仪器仪表内箱与外箱，轴承纸盒与外包装箱等)，除在内包装箱中采取防震措施外，在内，外包装箱之间，要根据货物的不同特点，衬以纸屑、瓦楞纸、泡沫塑料等防震材料或用金属弹簧悬吊，不允许货物在包装箱内或包装箱(盒)在外包装箱内产生窜动。
The inner lining of the wooden case is made of waterproof material. The outer cover of the goods and the top cover of the packing case are made of double-layer waterproof material structure. The plastic film used to cover the goods is generally not PVC. If it is used, measures should be strengthened to prevent it from directly contacting with the paint layer of the product. In the compound box packing with inner packing boxes (for example, inside and outside boxes of precision instruments, bearing cartons and outer packing boxes), in addition to adopting shockproof measures in the inner packing box, the inner and outer packing boxes should be suspended with paper materials, corrugated paper, foam plastics and other shockproof materials or suspended by metal springs according to the different characteristics of the goods, and goods shall not be allowed to be packed in boxes or boxes. There is movement in the outer packing box.
