Sandwich wrappers are materials used to enclose and protect sandwiches for storage and transport. They can be made from various materials, including paper, plastic, or foil, and are designed to keep the sandwich fresh while preventing spills and messes. Many wrappers are also printed with designs or branding, making them visually appealing. These wrappers are commonly used in delis, cafés, and for packed lunches. They help maintain the sandwich's shape and prevent it from becoming soggy. Additionally, some sandwich wrappers are biodegradable or recyclable, contributing to environmentally friendly practices in food packaging.
