Round glass Beverage Bottle or square glass Beverage Bottle ?
Both shapes, round or square, are important—whether in terms of attracting end users or influencing their purchasing decisions. Square and round glass bottles and glass jars have their own unique characteristics, and no one is superior to the other.
In order to make your choice easier, the factors you can consider when choosing the right product packaging shape are listed below: round glass jar or square glass jar.
1. Strength of glass jar:
Generally, the roundness of the bottle helps to balance the pressure on the entire surface. On the other hand, due to uneven pressure, square bottles are likely to have gaps in the corners.
2. Automation and conveyor belt handling:
Compared with square glass jars, machine filling products in round glass jars is faster and more efficient.
3. End consumer preferences:

Mechanical labeling on round bottles is relatively easy and consistent. If done manually, both are the same.

Therefore, the square shape is easier to attract the user's attention and help customers immediately recognize your brand.
