In the world of bottled products, cans hold a unique place. The history of canned bottles dates back quite a long time. In many TV shows that depict the early years of the People's Republic of China, it was common to see food items packed in glass cans. At that time, plastic bottles were not yet widely used, and glass cans were the mainstream packaging solution. These glass containers were coated with tinplate, offering excellent sealing properties. Additionally, they had the same size as regular bottles, making them easy to handle and remove. As a result, glass cans enjoyed a significant market share for many years.
Over time, with the rise of plastic bottles, glass cans gradually fell out of favor due to their higher production costs. However, in recent years, there has been a renewed interest in canned products such as fruit, pickled vegetables, and chili sauce. The straight-mouth design of glass cans makes them ideal for packaging these types of items. Combined with their strong sealing capabilities, this has led to a growing demand for glass cans once again.
It's not just glass cans that have seen improvements—plastic bottles, especially PET cans, have also gained popularity in recent years. Merchants have made significant advancements in the design and functionality of plastic cans. Compared to glass, plastic cans are lighter, which is a major advantage when it comes to solid foods like biscuits or snacks. This lightweight feature makes them more convenient for both manufacturers and consumers, further boosting their appeal in the market. With ongoing innovations and changing consumer preferences, canned bottles continue to play an important role in the packaging industry.
