During the hot summer season, it was the busy season for sales of various types of beverages. The reporter visited a supermarket in Kunming and discovered that many plastic bottled drinks were replaced with bright new clothes. Some bottles also had some concave lines on the surface. There was a great desire to purchase, and it took a closer look to find that the original capacity of beverages in the range of 550 ml to 600 ml was changed to 450 ml to 500 ml, while the 355 ml canned drink was shrunk to 330 ml. Only, the price remains unchanged. The raw material of the beverage bottle comes from petroleum. Industry insiders said that the recent market price of bottle PET PET particles is about 13,000/ton, and if a bottle saves 3 grams of net weight, what is the concept? At present, the domestic advanced mineral water production line can produce approximately 36,000 bottles per hour, and approximately 864,000 bottles can be produced in one day, equivalent to saving 2,592 kilograms of PET particles. Therefore, a line can save about 33,000 yuan in costs a day.
According to industry sources, companies must change their molds whenever they change bottle types, and replacing molds means bleeding. A set of molds requires about 4 to 5 million inputs. There are hundreds of production lines in the country. All production lines are equipped. Not a small number. Reducing the weight of the bottle is a difficult technology in the industry, especially the adjustment of mineral water bottles. The mineral water bottle net weight was 15 grams a few years ago, and most of them are now adjusted to 8-12 grams. Beverage bottles have also been adjusted from the original 25 grams to the current 20 or less, although the weight of a single bottle is only a few grams, but the cumulative increase, the company faced a situation of rising prices, has played a very good relief.
