Japan Food Distribution Systems Association developed a fresh-keeping cartons

This is a new type of carton developed by the Japan Food Distribution System Association in recent years. Researchers used a "Ristoval" (a type of silicate) as an additive to pulp. Due to this kind of stone powder, it has unique adsorption effect on various gases, and it is cheap and does not require low-temperature and high-cost equipment. It has a long-term preservation effect, and the weight of fresh fruits and vegetables will not be reduced, so businesses love it. With it, it is even more unique to carry out long-distance storage and transportation.
