What's wrong with bubbles around the vacuum packaging bag?

Yesterday, a customer left a message on the website asking a question, 'What's wrong with the bubbles around the vacuum packaging bag?' In response to this question, Jinde Packaging technicians provided a detailed introduction.

In fact, the question 'What's wrong with bubbles around the vacuum packaging bag?' I don't know if the consultant wants to understand whether the vacuum packaging bag itself has bubbles or if there are bubbles inside the bag after vacuuming. To solve this friend's problem, the following will provide detailed explanations on these two points.

1. If there are bubbles in the vacuum packaging bag itself, it is a quality problem of the vacuum packaging bag. Generally, those with a diameter less than 1mm and evenly distributed are called small spots, while those with a larger diameter can clearly see the delamination of the two layers of film, which is called bubbles. The reason for this problem is that the two layers of film are not tightly bonded together. It belongs to the quality issue of vacuum packaging bags, which should be noted when purchasing.
2. If there are bubbles inside the vacuum packaging bag after vacuuming, it is due to insufficient vacuuming and residual air inside the bag. The parameters of the vacuum packaging machine can be adjusted to solve the problem. If it is not easy to vacuum the product due to the packaging, a textured vacuum packaging bag can be selected. The surface of the textured vacuum packaging bag is pressed with small patterns, which can be opened into microchannels during vacuum pumping, greatly improving the vacuum pumping effect.

What is the reason for the bubbles around the vacuum packaging bag mentioned above? I hope the analysis and clarification can be helpful to everyone. If you have more questions, please feel free to call our hotline at 15902743510 for consultation
