well exposing this things to air can make them spoil meaning they put preservatives in the packet of the biscuits the preservatives arent perment so they could spoil in the case,while exposing them to air can make them soft leading to spoilage

Answer 2

Dry foods such as instant noodles, biscuits and potato chips can be stored for a long time because they contain very little moisture. Moisture is what causes food to spoil quickly. Dry foods that contain less than 10 percent of moisture are the perfect candidates for long-term storage. Anything higher than ten could be difficult. 13% is a crucial number, with any foods higher than that posing too high of risk towards bacteria, mold, and fungus growth.

To store dry food properly, it should be kept in a cool and dry place. The storage temperature helps determine the length of storage; the higher the temperature, the shorter the storage time. Dried foods are susceptible to insect contamination and moisture reabsorption and must be properly packaged and stored immediately.
