Vacuum bag refers to a packaging method in which a product is placed in an airtight packaging bag, and the air inside the bag is extracted to achieve a predetermined vacuum degree in the sealed bag. It can usually be divided into food vacuum bags, medicinal vacuum bags, electronic vacuum bags, high-temperature vacuum bags, low-temperature vacuum bags, powder vacuum bags, compressed food vacuum bags, sealed vacuum bags, etc. No matter what kind of vacuum bag is chosen for, the word "silk" will always be mentioned. So what does the number of silk in a vacuum bag represent? What is the difference between 16 silk, 19 silk, and 24 silk?
What does the number of threads in a vacuum bag represent?
Jinde Packaging introduces that the number of threads in a vacuum bag represents the thickness of the vacuum bag, and 1 thread is equal to 0.01mm, which is a commonly used non legal unit of measurement. 1 thread, in mechanical dimension measurement, 1 millimeter is usually divided into 100 parts, and the length unit represented by 1 part is called 1 thread. The larger the number of threads, the thicker the vacuum bag.
What is the difference between 16 silk, 19 silk, and 24 silk vacuum bags?
1. Thickness difference: 24 wire vacuum bags are thicker than 19 wire vacuum bags, and 19 wire vacuum bags are thicker than 16 wire vacuum bags. 16 silk refers to a vacuum packaging bag with a thickness of 16 silk on both sides, 8 silk on a single layer, and 16 silk=0.16mm. 19 silk refers to a vacuum packaging bag with a thickness of 19 silk on both sides, 9.5 silk on a single layer, and 19 silk=0.19mm. 24 silk refers to a vacuum packaging bag with a thickness of 24 silk on both sides, 12 silk on a single layer, and 19 silk=0.24mm.
2. Different gas barrier properties: 24 wire vacuum bags have better gas barrier properties than 19 wire vacuum bags; The gas barrier of a 19 wire vacuum bag is better than that of a 16 wire vacuum bag. Due to the large thickness of the 24 wire vacuum bag, its gas and oxygen barrier properties are strong, which can effectively extend the shelf life of food.
