Bags often become brittle when frozen and are prone to air leakage. To address this issue, the China manufacturer Gojun Pack has specially adjusted the material formula of the Low Temperature Vacuum Bag series. Even when placed in the deep-freezing layer at −30 ℃, the bags can maintain flexibility and will not crack easily when folded after being taken out. All of these features have been repeatedly tested at low temperatures. The sealing process of the bag opening is very solid, with a wide and firm heat-sealed edge; even if stored in the refrigerator for a long time after vacuuming, there will be no leakage caused by temperature changes.
The Gojun pack's Low Temperature Vacuum Bag also comes in targeted styles. For example, "Vegetables Low Temperature Vacuum Bag" and "Fruit Low Temperature Vacuum Bag" are particularly suitable for the needs of different ingredients. This vegetable product has a very good breathability, it won't let spinach, broccoli and other vegetables get stuck inside and rot their cores. At low temperatures, it can also reduce the formation of ice crystal, after thawing, the vegetables remain crisp and refreshing, not soft and limp.
The Fruit Low Temperature Vacuum Bag pays more attention to pressure resistance, for delicate fruits like strawberries and blueberries, when putting them in and vacuuming, the force will be milder, preventing the pulp from being crushed. The bag can isolate oxygen, preventing the water jelly from oxidizing and turning black over time, after thawing, it will still retain its original color and texture.
