Answer 3

Strength.

Try putting a some normal shopping item in a thinner mag. The eggs (or milk) will fall out and be smashed or split by the bag of spuds!

Handles stretch and break on thinner bags!

Thinner bags also puncture easily from corners of cartons and then more shopping falls out of the holes while you are walking to the car!
