Based on cost considerations, only shells in domestically-made materials use wooden packaging. The packaging of imported materials is generally divided into the original package and color package. The original package is generally used for the packaging of genuine materials. The color package is generally used for the packaging of deputy brand materials. The transportation of imported materials generally needs to be carried by shipping, railways, or motor transport. There are many procedures for loading and unloading. In order to prevent the occurrence of broken packages, wooden trays and plastic trays are generally equipped. The cost of wooden trays is approximately 50 yuan/ton higher than that of bulk carriers, and the cost of plastic trays is approximately 100 yuan/ton higher. Purchase plastic packaging products.
