cardboard. Value Packaging: Each package contains 50 4-inch square paper deli boxes and 50 clear lids, enough for daily and party use. Material: The mini deli boxes are made of solid cardboard, and the clear lids are made of food-grade PET plastic, which are sturdy and recyclable. Greaseproof: There is a layer of polyester coating on the inside of these bread boxes, which can effectively avoid the penetration of oil and sauce. With Lid: The raised lid not only provides more space for food, but also isolates dust. The embedded design on the four corners can make the lid fit tightly with the take-out dessert container to prevent food leakage. Widely Used: These disposable food containers are perfect for packaging mini cakes, cupcakes, muffins, donuts, cookies, sandwiches, hamburgers, French fries, chocolate bombs, chocolate strawberries, snacks and desserts.
