Q6. Are paper cans waterproof and moisture resistant?

Yes, paper cans can provide excellent moisture resistance and protection when designed with the right structure and materials.

Standard paper cans are made from multiple layers of paperboard and can be customized with moisture-resistant coatings, aluminum foil lining, PE film, or inner bags to improve barrier performance.

For products requiring higher protection, such as coffee, nuts, snacks, spices, and powdered foods, composite paper cans with sealing lids and inner barriers are recommended to prevent moisture, oxygen, and external contamination.
