You will face criminal responsibility for drinks that cost 50 cents. The reasons are as follows: Food and beverage products need at least drinking water and food-grade additives as contents and food-grade packaging materials. So the equipment needs at least water treatment system, bottle blowing machine, filling machine, shrinking machine, inkjet printer and other equipment. If semi-mechanized bottle blowing and manual filling are adopted, the output per minute will not exceed 4 bottles. And you need to buy PET bottles and caps or two-piece cans and three-piece cans. Then the price of 50 cents is impossible to meet the requirements of food grade.
Once harmful ingredients are detected in products produced with non-food grade containers and contents, they will be prosecuted for harmful food production and sales.
For the safety of your investment and the health of consumers, please think carefully!
