For small and medium-sized enterprises with limited manpower and material resources, instead of using a large amount of manpower and material resources for the development of PET beer bottles, it is better to invest limited manpower and material resources in the development of packaging containers of PET bottles in the fields of daily chemistry, medicine, food and condiments, etc. In order to obtain better practical benefits. In the polyester packaging container, another variety worthy of the attention of the industry is the APET sheet hot forming vessel mentioned earlier. It has the advantages of less one-time investment, less technical difficulty, excellent product performance, low price and wide application. It has huge development space. We should strengthen the development of APET thermoforming container.
