Benefts of Glass Bottles
New ways of glass packaging are as follows:
1.Adopt advanced energy saving technology.

Another way to save energy, improve melting quality, and prolong the service life of the furnace is to increase the amount of broken glass, and the amount of broken glass from abroad reaches 60%-70%.The ideal is to use 100% cullet to achieve the goal of “ecological” glass production
2.Lightweight bottles and cans.
In developed countries such as Europe, America and Japan, lightweight bottles have become the leading products of glass bottles.80% of the glass bottles and jars produced are lightweight disposable bottles.The precise control of raw material composition, the precise control of the whole melting process, the small mouth pressure blowing technology (NNPB), the hot and cold end spraying of bottles and cans, the on-line inspection and other advanced technologies are the fundamental guarantees for realizing the lightweight of bottles and cans. Some countries are developing new surface enhancement technologies for bottles and cans in an attempt to further reduce the weight of bottles and cans. For example, Germany Heye Co., Ltd. coats a thin layer of organic resin on the surface of the bottle wall to produce a 1-liter concentrated juice bottle with only 295 grams, which can prevent the glass bottle from being scratched, thereby increasing the pressure strength of the bottle by 20%.The current popular plastic flm sleeve label is also conducive to the lightweight of glass bottles.
3.Increase labor productivity.
The key to improving the labor productivity of glass bottle manufacturing is to improve the forming speed of glass bottles. At present, the commonly adopted method in developed countries is to use multi-group and multi-drop forming machines. For example, the speed of 12 sets of double-dropping determinant bottlemaking machines produced abroad can exceed 240 pieces per minute, which is more than 4 times higher than the 6 sets of single-dropping forming machines commonly used in China. In order to ensure high-speed quality and high molding pass rate, electronic timers are used to replace traditional cam-type drums. The main actions use molding parameters, which can be optimized according to requirements. And cold end online inspection system automatically rejects waste.
