Why do food vacuum packaging bags inflate?

Food vacuum packaging bags, also known as pressure reducing packaging, are used to extract and seal the air inside the packaging bag to maintain a highly depressurized state. Food vacuum packaging bags use the principle of deoxygenation to effectively prevent food spoilage, maintain its color, aroma, taste, and nutritional value. It should be noted that once the vacuum packaging bag for food expands, it loses its vacuum effect. So why do food vacuum packaging bags inflate?
Why do food vacuum packaging bags inflate? Jinde Packaging explained that there are several reasons for this:
1. Leakage problem: The sealing of food vacuum packaging bags may have issues, causing gas to re-enter the bag. Check if the bag opening is properly sealed and if there are any air leaks, such as damaged bag openings or other small holes.
2. Material breathability: Some food vacuum packaging bags may use materials with relatively high breathability, which means that although the gas inside the bag is extracted, fresh air can still penetrate into the bag through the material. Switching to high-quality food vacuum packaging bags can help solve this problem.
3. Temperature changes: Temperature changes may also cause the gas inside food vacuum packaging bags to expand again. When the bag is exposed to higher temperatures, the gas will expand and refill the bag. If this is one of the reasons for the bag to re inflate, trying to store the bag in a cooler environment can slow down this process.
