How much investment does it take to run a plastic bottle factory (drinks, daily chemicals)? How is the market now? thank you

Plastic bottles include blow molding. There are two kinds of blow molding: direct blowing and combined blowing. Direct blow molding is extrusion blow molding. Generally, machines under 200g cost about 654.38+10,000 yuan, and then they are blown into tube blanks for blow molding. Firstly, the tube blank is produced by injection molding machine, and then the tube blank is heated before blow molding. The price of a bottle blowing machine below 500ml is about 25,000 yuan, and that of an injection molding machine below 200g is about 10 yuan.
