Glad Food Storage Bags prevent food from being destroyed and dried out with freezer burn. These bags have an extra tight and wide closure, which locks in freshness easily and securely. The extra thick and durable plastic help to ward off freezer burn by preventing air from reaching the food. These bags are BPA free and microwaveable so you can safely defrost your food in the microwave. Glad bags are great for storing fruit, cheese and meat in the refrigerator, and also the perfect size for storing tools, toys, travel toiletries, and many other smaller items. With the Yellow and Blue Make Green seal, you know when the bag is fully closed. Using Glad bags give an extra level of protection for your food and for your things.
