The meaning of "PK" in chewing gum has two potential explanations, both related to the Wrigley family and its history.
Potential Meanings of "PK"
There isn't a definitive, universally agreed-upon answer. Instead, two different theories exist within the Wrigley company itself:
-
"Packed tight, kept right": This theory suggests that "PK" is an abbreviation of a popular slogan used by packaging regulators at the time of its creation. The slogan emphasized the importance of proper packaging for maintaining the quality of the chewing gum.
-
Philip Knight Wrigley: Another belief is that "PK" was a tribute to Philip Knight Wrigley, the CEO of the Wrigley confectionery company from 1925 to 1961. This would have been a way to honor his leadership and contribution to the company's success.
Therefore, the meaning of "PK" is open to interpretation depending on which origin story you subscribe to. Both theories have a basis within the history of Wrigley's chewing gum.
