Why can the canned fruit be in a glass bottle and the canned meat in an iron box?
In fact, almost all canned foods can be packaged in metal cans. Moreover, glass jars are heavy, brittle, and costly. As a simple example, a 500ml metal can weighs about 20-40g, while a 500ml glass can weigh 200-350g. Therefore, glass-packed products are more expensive to transport than metal packaging, and it is not very convenient in actual production and transportation. Therefore, in countries with large canned food consumption such as Europe and the United States, most of the canned foods on the market are metal cans.
However, due to its transparent nature, glass jars have a good display effect on the food itself, which can improve the product selling phase. For countries in China where the acceptance of canned foods may not be very high and the consumption of canned foods is not very large, this can attract consumers. Therefore, some canned fruits will use glass bottles.
In general, glass jars are costly, and only good-looking foods use glass packaging when they need to attract customers. The canned foods such as meat and chicken noodle soup are sold after a long period of high temperature treatment. The relatively cheap and ugly metal cans are the best choice!
