When I grew up in Sweden, soda was sold in standardized glass bottles. All brands used the same bottles and they just put paper labels on. You'd return the glass bottles for a deposit, they'd take them in, remove the label, wash then and refill them. You could tell how old the glass bottle you were drinking out of was by how scratched the label was.

In the 90's, they were all replaced by PET bottles. We were told at the time that this was because the oil used in the plastic bottles was still less than the extra oil used to ship the heavy glass bottles back and forth.
