What is the difference between aluminum foil and true foil in an aluminum foil bag?
In plastic material, we have normal aluminum foil and true foil.
When putting a light inside the normal aluminum foil bag, the light can be seen from the outside of the bag, but if you put a light inside the true foil bag, the light is gone.
This means the true foil material can shield the light well and will keep the coffee bean fresh for a long time storage even in sunlight.
If you need to know which will be more suitable for your package, please kindly send an inquiry to us or contact our sales directly.
