250g Empty Tin Coffee Cans , 9OZ Metal Tin Cans With Valve ISO9001 Certified

Freshness Preservation: The combination of vent holes and exhaust valves allows for controlled airflow within the cans. This ventilation system effectively releases any excess gas, primarily carbon dioxide (CO2), while preventing excessive exposure to oxygen. By regulating the gases within the can, it ensures optimal freshness and flavor retention of the coffee beans, keeping them at their peak for longer.

Aroma Lock: The ventilation system in our metal cans is designed to balance airflow, effectively retaining the rich aroma of the coffee beans inside while preventing the entry of any undesirable odors or flavors. This ensures that every time you open the can, you are greeted with the enticing and tantalizing aroma of freshly roasted coffee.

Consistent Roast: The presence of vent holes and exhaust valves helps maintain a consistent roast level of the coffee beans. It allows for the controlled release of CO2, a natural byproduct of the roasting process. This ensures that the coffee beans reach their optimal flavor profile and prevents them from becoming stale or losing their freshness prematurely.
