A grease proof sandwich bag is a lightweight, food safe paper bag designed to prevent oils and moisture from seeping through. Made from specially treated grease resistant paper, it keeps hands, surfaces, and other items clean while preserving the freshness and appearance of the food inside.
These bags are ideal for sandwiches, pastries, cookies, baked goods, wraps, and snacks that may contain butter, cheese, sauces, or natural oils. They provide a simple, eco friendly alternative to plastic packaging and are commonly used in cafés, bakeries, delis, and lunch settings.
