Oxford Premium Lining and Zipper: The lining of the lunch bag is made of PEVA aluminium foil, which will not melt easily when the bag is loaded with something hot. At the same time, we use high quality zippers to minimize the possibility of zipper damage. Long-term insulation: Lunch bags are made of insulation material to keep food and drink cool or warm for more than 5 hours. Plenty of space for all the lunches you want (lunch boxes), cans, fruit, water bottles, snacks) suitable for work, outdoors and travel. You can use it as an ice pack, a lunch bag, a clutter or shopping bag, a snack bag for long trips, or a ladies' or men's convenience bag
