Had been producing OPP film structures for food packaging; which had the largest share in consumption; until the early 1990s. After all; the concentration in the fast moving consumer goods was on the foodstuffs rather than the cleaning or cosmetic materials. The fundamental feature of foodstuffs; on the other hand; is very high market circulation; i.e. they can be sold out rapidly without waiting
on the shelves for long time. Under these circumstances; it is unnecessary for the flexible packaging materials used to wrap up the foodstuffs to have very high barrier feature. When the foodstuffs like biscuits; candies; legumes; macaroni; dried nuts; etc. are packaged in a material with medium barrier feature; like OPP film; they could remain fresh sufficiently when bought by the end user.
