1. Why do coffee bean bags need a one-way degassing valve?
The valve lets carbon dioxide escape from freshly roasted beans without letting oxygen in, preventing the bag from bursting while keeping coffee fresh and flavorful.
2. What material keeps coffee beans fresh longest?
Aluminum foil laminates (e.g., PET/Alu/PE) offer the best barrier against oxygen, moisture, and light, preserving freshness for up to 2-3 years.
3. Are coffee bean bags recyclable?
Yes, mono-material PP or PE bags (including the valve) are fully recyclable in standard plastic streams, offering an eco-friendly alternative to traditional foil-lined bags.
