Produce bag with selective gas permeability
Abstract:
Described are gas-permeable bags for storing respiring materials. The bags can be formed using a single sheet of a sturdy, transparent, gas-impermeable material to facilitate the viewing of bag contents. The bags can also include two or more gas-permeable walls with respective and different gas-transmission rates that are selected so that the overall gas-transmission rates for the bags are tailored for their contents. The types of films and laminates used for the gas-permeable walls exhibit gas-transmission rates for oxygen, carbon dioxide, and water that are favorable for different types of respiring materials.
