Aluminum foil composite bags
Strong barrier properties: Aluminum foil has excellent barrier properties, blocking oxygen, moisture, and light, thereby preventing coffee beans from oxidizing, becoming damp, or being affected by light, thus preserving their flavor and quality.
Durable: This material is strong and resistant to damage, providing reliable protection for coffee beans during storage and transportation.
Aluminum-coated composite bags
Good barrier properties: The aluminum coating provides the packaging bag with good barrier properties, reducing the intrusion of oxygen and moisture, which helps extend the shelf life of coffee beans.
Cost advantage: Compared to pure aluminum foil composite bags, aluminum-coated composite bags are relatively inexpensive, offering a high cost-effectiveness ratio while ensuring adequate freshness.
Coffee bean octagonal seal bags Kraft paper composite bags
Excellent environmental friendliness: Kraft paper is a recyclable eco-friendly material. When combined with moisture-proof and oxygen-barrier materials such as aluminum foil or plastic film, it enhances both environmental friendliness and freshness retention.
Good light-blocking properties: Kraft paper has a dark color and provides some light-blocking effects, reducing the impact of light on coffee beans.
Coffee bags with exhaust valves
Regardless of the material chosen, to better preserve freshness, one-way breathable valves can be added to the packaging bags, allowing coffee beans to release carbon dioxide while preventing external air from entering.
