Basically speaking, there are five kinds of package for soap.
1.in pearlized film, one or two sides with lable sticker,mostly used for 10-50g soap. It is the cheapest one and mostly used.
2.in paper wrap, one or two sides with lable sticker, mostly used for 10-50g soap. A little more expensive then the first one but it is eco-friendly.
3.in cellophane, it mostly used for transparent soap, it is visual for customer to see the product.
4.in sachet with logo printing.It is cheaper than card box, but not as economic as the above two.
5.in opp, then in card box with logo printing.Card box makes soap more high-end.
