What Is a 26 / 29 mm Aluminum Crown Cap?
A crown cap is a metal bottle closure that seals the mouth of a glass bottle through crimping. It is named for its crown-shaped edge. Common sizes include 26 mm and 29 mm.
26 mm Crown Cap
Widely used for beer bottles and some soda bottles. It is the global standard size in the beer industry.
29 mm Crown Cap
Primarily used for beverages with higher internal pressure, such as carbonated drinks, energy drinks, and sparkling water, where sealing and pressure resistance requirements are higher.
Aluminum offers inherent advantages such as lightweight construction, corrosion resistance, and recyclability, making it a widely recognized safe packaging material in the food and beverage industry.
Why Choose Aluminum Crown Caps?
Compared with traditional tinplate materials, aluminum has clear advantages: lower weight reduces transportation costs; excellent formability enables more complex shapes and printing designs; and aluminum is odorless, helping preserve the original taste of beverages.
