How much silk is good for vacuum packaging bags?

The principle of vacuum packaging bags is relatively simple, which uses the method of deoxygenation to extend the shelf life and improve the quality of the packaged products. It can be seen that the effectiveness of vacuum packaging bags mainly depends on the airtightness of the vacuum bag. However, it is not as people think that the thicker the vacuum bag, the higher the airtightness. So, how many threads are good for vacuum packaging bags?

Jinde Packaging introduces that in order for vacuum packaging bags to complete packaging tasks in sales, transportation, and retail processes, it is necessary to choose vacuum packaging bags with suitable thickness, which also depends on the size of the packaged capacity.

For example, if the packaging capacity ranges from a few grams, tens of grams, hundreds of grams, to several kilograms or more, the thickness of this vacuum packaging bag generally needs to be between 2.5-20 microns, that is, 25-200 microns.

2. For packaging bags of several grams or tens of grams, such as Wangwang Snow Cake, heat sealed OPP material can be used, with a thickness of 2 or 2.5 threads. For example, there are foods with bones and spines, such as vacuum packed roasted chicken and duck necks, which can have a thickness of about 15 threads.
3. Packaging of 5kg and 10kg rice with larger capacity can achieve 18 strands.

For vacuum packaging with a capacity exceeding 10 kilograms, it is called heavy packaging. Generally, heavy packaging requires processing with composite materials and a thickness of about 25 threads.

The types of vacuum packaging bags are very diverse, and it is not a matter of constant conditions. Here is just a simple sharing.
