摘要： A packaging material, which is capable of absorbing trace amounts of volatile odorous sulfur compounds particularly from food, is made from a structural support material which is preferably a polymer film, and a defined molecular sieve. The packaging material may be in the form of a film which forms at least one layer of a film package, or it may be in the form of a cap liner, or it may be in the form of an insert. Film materials may be oriented film or oriented shrink film. The molecular sieve may be defined either by its measured ability to adsorb hydrogen sulfide, or by certain physical and chemical structural parameters of the molecular sieve. These are pore-opening size, Si/Al atomic ratio, pore-structure dimensionality, and basicity.
