Why do you make the lining of a picnic box with PVC foam?

Using PVC foam to line a picnic box offers several advantages. It is lightweight, durable, and resistant to moisture, which helps protect the contents from spills and humidity. Additionally, PVC foam provides cushioning, preventing damage to fragile items, and is easy to clean, making it ideal for outdoor use. Its insulation properties can also help maintain the temperature of food and beverages.
