Why are some sticks of gum stamped with pattern or initials?

Some sticks of gum may be stamped with patterns or initials as a trademark or branding strategy by the manufacturing company. These patterns or initials help identify the gum brand and create a unique visual association, making it memorable for customers. They also serve as quality checks and help identify any issues during the production process. Some gum brands use specific patterns or designs stamped on the gum or packaging to indicate different flavors or gum strengths.
