Never noticed holes, except for needle holes where they are sewn closed.
Could yours be conveyor belt induced holes, to get traction when they are
filled and loaded?

So peeping toms like you can spy on the cement without opening the
bag.

Its so the worms can breath. Thats where they breed the worms for the worm
drive saws. See worm drive saw post.

The holes are there because of how the bags are filled. The bags are
actually closed except for a small opening near the top that accepts
the feeder (basically a 2-3" tube). An operator will simply slip the
bag over this tube and the bag is filled with concrete. The weight of
the concrete will then push against the opening to close it. If there
were not holes in the bag, then the bag would explode while being
filled from the increase in pressure. The same technique is used to
fill large bags of dog food, cat litter, etc.
