Why is it suitable to put ketchup in a glass bottle?

Putting ketchup in a glass bottle is suitable because glass is non-reactive, preserving the flavor and freshness of the condiment without leaching any chemicals. Additionally, glass provides an airtight seal that helps maintain the ketchup's consistency and prevents contamination. The aesthetic appeal of glass can enhance the dining experience, making it more visually appealing on tables. Lastly, glass is recyclable, making it a more environmentally friendly option compared to plastic.
