Replacing other materials
Paperboard can be used, with significant gains, to replace other packaging materials. Its properties make it a good choice for many packaging applications. For example replacing:
Plastic – Significantly lower carbon footprint. In many applications a paperboard box saves more than 75% of the fossil carbon emissions compared to a similar packaging in plastic. For the application above, the gift card, you can save more than 95% of the carbon footprint by going from plastic to paper.
Glass - Lighter and less brittle. The weight of a paperboard container is often a fraction of a glass jar of same size, making transportation much less fuel demanding.
Metal - Lower energy use. The fossil energy used to produce a metal can for food packaging is usually enough to produce 10 similar paperboard packagings and still have a lower emission of fossil CO2.
