Regard to the "Happosai",
we have to weigh the vegetable one by one,and put in the bag one by one.
Once we put 4 vegetable in 1 bag and seal it,we will mix well.
We have to put the vegetables in the bag at same ratio.
If we mix vegetables before put in the bag, some bag has a lot of "Carrot",and others has a lot of "Young corn".
This is not acceptable in Japan.
So we have to weigh one by one then separately put in the bag.
I checked your file,that said mixing before put in the bag.
This is not acceptable.So please check it,if I misunderstand that is OK.
But if you misunderstand,please think again.
