The shipping costs of bottle caps are much lower than those of plastic bottles and glass bottles. Therefore, it will become more flexible in the location of the company. However, if bottle cap manufacturers want to gain more advantages, they still have to follow some principles of site selection. The following are some aspects that I think bottle cap manufacturers should consider in site selection. First of all, bottle cap manufacturers and glass bottles, plastic bottle manufacturers should be as close as possible. Because, a large part of the cap manufacturers manufacturers are plastic bottles, glass bottles factory. At the same time, where the plastic bottles and glass bottle manufacturers are concentrated, the relevant supporting facilities are perfect and easy to sell. Secondly, the user groups of bottle caps include wineries and food factories. It is even more advantageous to locate sites where these manufacturers concentrate. Finally, part of the bottle cap is the foreign trade market. The establishment of a site at the coast and foreign trade ports is also more conducive to the development of foreign trade orders. In short, for bottle cap manufacturers, we must start from many aspects. Although flexible, we should try our best to choose a place that is close to the buyers, which is more conducive to sales.
