The wall of a composite paper can consists of three layers: an inner aluminum
foil layer for moisture and oxygen barrier protection, a middle layer that provides
structural strength, and an outer label layer. The outer layer supports a wide range
of paper materials—from coated art paper to specialty paper—offering flexibility in
design and texture. Combined with various sealing options, the result is a tightly
sealed, cylindrical container that is both functional and visually appealing.
