Our FoodVacBags vacuum sealer rolls are designed with a metallic back and clear front, for the perfect display of your products. The thick, heavy-duty, honeycomb embossed rolls provide long-term protection for your food and non-food items. The exclusive embossed pattern air-removal channels increase suction for maximum freshness. Our vacuum sealer rolls increase 5 to 6 times longer freezer storage time, locking in freshness, flavor and nutritional value. Our vacuum sealer bags are BPA free, phthalate free and provide excellent protection from freezer burn and dehydration. *These metallic bags are thick and sometimes do not work with low quality vacuum sealers. Make sure you have a powerful sealer!*
