(Note that there is no hole present on the above packaging)

My Question:

What is the advantage of having a hole on one's coffee packaging v.s. not having one?

The existence of the de-gassing vent was answered here:

What is the clear plastic sticker on New England Coffee bags for?

If the manufacturer does not feel that the coffee (usually whole beans) will need C02 venting, there will be ho holes or vents. That will be the case if the coffee is packaged a week or so after roasting.

some boutique coffee packages have an aroma vent - for you to squeeze the bag and smell the coffee.
