It is not just convenience. It is also cost. How many customers will be willing to pay a $ or more just for the packaging? Every alternative to plastic is much more expensive. For instance, take glass. Glass bottles break very easily during transport and they are also more expensive to purchase. If you are thinking of recycling them, that too adds cost in the process - from pickup, cleaning, drying etc. The holy grail for packaging would be a transparent, flexible, glass-like substance that is also extremely inert and which doesn't absorb the contents, doesn't spoil, doesn't allow air in or out, retains shape for a long time.... and yet can be decomposed!! As you can see this is a tall order.
