How are the weight and thickness of non-woven bags measured, and what tools should be used to measure them?

How to measure the weight of non-woven bags is a misunderstanding when many friends first touch non-woven bags. Today I want to tell you how to measure the weight of non-woven bags. So, here will be a brand of coated handbag as a measurement case, I hope it can help you have the needs of friends. First of all, we have a non-woven bag on hand, knowing the thickness of the cloth in grams, we need to find a professional tool to measure it. And this is not measured with a caliper or ruler. This is not the true thickness. However, a non-woven bag is regularly dug out with professional tools, and then accurately weighed with a weight accurate to 0.01 grams, and then the weight is the weight of the thickness of the fabric. This is how many grams of fabric we use to make non-woven bags. Of course, there is another aspect that needs attention. If it is a coated non-woven bag, it is necessary to distinguish the grams of three materials. The first is the raw non-woven fabric, the second is glue, and the third is PP. Generally speaking, the thickness of all laminated non-woven fabric glue and PP film will not change. A bag always maintains the appearance of 20g glue and 15g PP film, but the real control of the fabric thickness still depends on the control of non-woven fabrics. At this point, it is necessary to mention the thickest and thinnest coated non-woven fabrics. Generally coated non-woven fabrics are usually used for the most commonly used thicknesses of 90g-120g. If it is less than 90g, remove the glue and the thickness of the PP film, so the thickness of the non-woven fabric is only 55g. If the film is on this thick non-woven fabric, the coated non-woven fabric will be like plastic, and it will lose nothing. The texture of the woven fabric should be. For fabrics larger than 120g, it should be noted that the fabric can be manufactured without affecting the texture of the entire product. However, as we all know, the current non-woven bags are formed by machines, and they are all heat-compressed by ultrasonic and high temperature. Therefore, once the fabric is thick, the equipment cannot complete the interface of the fusion bag. Do you know how to measure the weight of non-woven bags?
