Vacuum bag packaging is one of the most effective ways to preserve food. Vacuum bags help preserve food for a long time. With these bags, you can seal food or snacks to increase their shelf life. This is the best way to avoid bacterial growth or reduce food spoilage.
Vacuum bags usually do not need printing, but for some high-grade frozen foods, there are still some simple printing. Our company has been producing vacuum bags for many years, and we provide vacuum bags for companies like frozen food, meat and fish products to meet their huge demand in food packaging.
--What material are the food vacuum bags made of?
Food vacuum bags are made of plastic or polymer materials.
The plastic must be flexible enough to handle the vacuum process.
In other words, the plastic will adapt to the shape of the food you store in the vacuum bag.
--Why Use Food Vacuum for your Product?
The reason you should choose a food vacuum bag is that it prevents food oxidation by preventing bacteria, fungi, oxygen, light, water, and other barriers and bacteria.
It also provides consumers with the ability to store fresh flavors for a long time before eating.
--How to use vacuum seal food bags
The main function of vacuum packing is not only to keep oxygen and quality but also to resist pressure, prevent gas, and keep fresh, which can effectively keep the original color, aroma, taste, shape, and nutritional value of food for a long time. Besides, many foods are not suitable for vacuum packaging but must be filled with vacuum packaging. Such as crunchy and fragile food, easy to agglomerate food, easy to take the deformation of oil food, there are sharp edges and corners or high hardness will puncture packaging bags of food. After the food is packed in a vacuum environment, the air pressure inside the bag is higher than the atmospheric pressure outside the bag, which can effectively prevent the food from crushing and deformation under pressure without affecting the appearance and printing decoration of the bag. Vacuum packing is filled with a single gas of nitrogen, carbon dioxide, oxygen, or a mixture of two or three gases after a vacuum. Nitrogen is an inert gas, which plays a filling role to keep the positive pressure inside the bag and prevent the air outside the bag from entering the bag, thus playing a protective role for food. Its carbon dioxide can dissolve in all kinds of fat or water, and lead to carbonic acid, which has the activity of inhibiting mold, putrid bacteria, and other microorganisms. Its oxygen can inhibit the growth and reproduction of anaerobic bacteria, and keep the freshness and color of fruits and vegetables. The high concentration of oxygen can keep the fresh meat bright red.
--Advantages of using vacuum seal food bags
High barrier: the film is co-extruded with high barrier properties of different plastic materials to achieve the effect of high barriers such as oxygen, water, carbon dioxide, and smell.
Stable performance: oil resistance, moisture resistance, low temperature and freezing resistance, quality preservation, fresh preservation, odor preservation, can be used for vacuum packaging, aseptic packaging, inflatable packaging.
Low cost: compared with glass packaging, aluminum foil packaging, and another plastic packaging, to achieve the same barrier effect, co-extrusion film has a greater advantage in cost.
