ALBAL's MEDIUM HERMETIC FREEZER BAGS feature a design with a flat base, ensuring that the bags are easy to fill without mess. They come with a dual sealing mechanism, allowing you to access only the desired food portions. A new flap provides a simple way to open and securely close the bag while maintaining an airtight seal. Made from durable materials, the Albal® Ultra-Zip® freezer bags are suitable for freezing foods at temperatures as low as -40ºC and can also be used for heating by submerging them in water up to +90ºC. This makes these bags a practical choice for families that prepare large quantities of pre-cooked meals, as they allow for individual portion freezing, facilitating easier thawing.
