Edible oil bottle packaging needed to diversify

For edible oil bottle packaging, capacity is given priority to with 5 l. Such large capacity compared to other food packaging is less. Because food many has a shelf life. For 5 l such edible oil bottle packaging and what are the strengths and weaknesses?

in terms of advantage, 5 l of edible oil bottle packaging for some of the family, the small restaurant heavy oil, obviously more convenient, need not often go to buy cooking oil. However, the large capacity of edible oil bottle packaging is also has a lot of problems. First of all, 5 l capacity obviously use at ordinary times must pour oil out of the bloom caster in, otherwise is not convenient to use, especially our housewives to use more constant. Next, the capacity of 5 l for the average family, a lot of time to one or two months to finished. Often open, easily lead to bacteria invasion, cause health problems.
so, though the 5 l edible oil bottle is the mainstream market, but we think that still need more edible oil bottle packing type to supplement the market demand of various kinds of differentiation.
