What is the primary purpose of the wrap used for sandwiches?

The primary purpose of the wrap used for sandwiches is to keep the sandwich free of debris. This is essential for maintaining hygiene and ensuring that the food remains appetizing and fresh until it is ready to be eaten. The wrap serves as a barrier that protects the sandwich from external contaminants, such as dirt or dust, while also preventing the ingredients from drying out or becoming soggy.

While enhancing flavor and providing insulation are notable qualities, they are not the main functions of a sandwich wrap. Similarly, while decoration can be a secondary consideration in some contexts, it does not serve the primary function of protecting the sandwich. Thus, the wrap’s role in maintaining cleanliness directly supports its core purpose in food service and consumption.
