[China Glass Net] For glass bottle packaging, the current trend of glass bottle lightening has become more and more obvious. The defect that the glass bottle is too heavy and too thick makes it lose the opportunity to compete with the plastic bottle. At the same time, it costs for the manufacturer. More raw materials also mean an increase in costs. Therefore, the demand for lightweight and weight-reducing glass bottles has become more and more high in recent years.
The lightweighting of glass bottles saves a lot of raw materials, which means a cost reduction for one glass bottle manufacturer. On the other hand, as the weight of the glass bottle is reduced, the logistics cost during transportation is also greatly saved. The many advantages of lightweight glass bottles make the current industry expect a lot.
Glass bottle lightweight is not a generalization
However, the weight of glass bottles is not as good as it looks. The lightweight technology of glass bottles is difficult to overcome. The bottle must withstand a certain amount of pressure, the bottle wall becomes thinner, and the ability of the glass bottle to withstand pressure will drop rapidly. So this lightweight technology is difficult to overcome. In terms of people's consumption habits, the thick texture of the glass bottle can reflect the grade and luxury of a product. Many high-end products use glass bottle packaging for this reason. Lightweight will make the glass bottle lose this advantage. In addition, similar to the wine glass bottle, the wine has certain requirements for the color of the bottle body, not the thinner the better.
For some glass bottles that have no special requirements, such as ordinary food glass bottles and dried fruit glass bottles, it is necessary to reduce the weight of the packaging. The weight reduction not only reduces the cost, but also makes the consumers more convenient to carry. However, there are still many glass bottles that are not suitable for weight loss. Champagne is also known as sparkling wine, which produces a lot of air pressure. Therefore, for a champagne bottle, if the weight is reduced, it is difficult to grasp the wall thickness of the glass bottle. Champagne bottles are easily broken during transport or use, thus losing the meaning of weight loss in champagne bottles.
Therefore, we must support both the weight loss of the glass bottle and the specific analysis according to the specific situation.
