Aluminum foil VS Metallized film:
When we choose to make an aluminum foil bag, there have some points we need to know before we get started.
-Aluminum foil is a high barrier film, the biggest advantage is 100% lightproof.
-Want to make a pouch with a window? Use metalized film instead of aluminum foil cos aluminum foil can not do that in craft in current.
-Metalized film is lower barriers than aluminum foil, but its cost is cheaper.
-Not all products need very high barrier properties, knowing your proper needs is the keypoint, and metalized films are not weak as well.
-Surface: ALuminum foil is one side matte and one side slightly shiny on look, Metalized film is shiny in both side.
– Shelf time of laminated aluminum foil is 18-24 months, and laminated metalized film is 12-15 months. Shelf life depends on your storage condition as well.
