The changing environment of food packaging is characterized by globalization, protection of the global environment, eating by oneself, and food safety. Delicious-looking food descriptions are printed on food packages to induce the consumer to pick up a product at the store, and nutritional, allergy, product liability, and recycling data are provided as legally required. Printing technology features such as high resolution and ink expressiveness make it possible to display such information, and this technology contributes to the creation of value through packaging. Considering the future of packaging printing, we expect food packaging to create real value: for example by adding security, preventing food loss, and providing a high level of visibility. In order to formalize the logistical quality of packaging, an easy-to-understand and established standard is needed. To this end, we implemented standardization by: 1. Classifying the necessary information; 2. Defining the space; and 3. Designating the size, dimension, and font to be used. Additionally, we improved the stacking efficiency at the pallet level by a reverse design procedure (outer package → number of package → inner package → individual package) and by using a quick reference chart of the pallet pattern. Taking the packaging process as a whole, the proportional cost of the printing process to the life cycle assessment is low. However, its potential function is very important and I believe that printing can create significant new value in packaging. Due to information overload and the extreme difficulty of making good judgment calls, I expect printing technology for food packaging to provide only the necessary information on demand.
