Non-woven fabric is one of the more popular fabrics on the market. It is a fabric that does not need to be spun and weaves, but the short fibers or filaments are oriented or randomly arranged to form a web structure. Then it is reinforced by mechanical, thermal bonding or chemical methods. Usually it can be made into handbags, and higher grade non-woven fabrics can be made into medical masks, medical protective clothing, etc. Non-woven fabrics can be customized from 10 grams to 260 grams. The thicknesses often available in the market are 25 grams, 30 grams, 45 grams, 60 grams, 75 grams, 90 grams, 100 grams, 120 grams and so on.
Generally speaking, the thickness of non-woven materials used for promotional materials, advertising bags, gift bags, and shopping bags are 60 grams, 75 grams, 90 grams, 100 grams, and 120 grams. However, it is mainly determined according to the weight that the customer needs. Among them, 75 grams and 90 grams are the thickness chosen by most customers.
Generally, 25 grams to 60 grams of materials are used for the moisture-proof and dust-proof packaging bags for shoe covers or wallets and electronic products. The moisture-proof and dust-proof bags for the packaging of luggage or bulky products generally use materials of 50 grams to 75 grams.
So how should we choose the thickness of the non-woven material?
For example, if we want to use non-woven fabric to make non-woven fabric handbags, we should first know that the material specifications of non-woven fabric handbags are calculated in grams (g). Under normal circumstances, non-woven shopping bags are mostly 70 to 90g, so how to accurately choose the customized thickness? First of all, it is necessary to clarify that the load-bearing capacity of different thicknesses is not the same. A 70g bag generally bears about 4Kg. 80g can bear about 10Kg. Above 100g can bear about 15kg. Of course, it depends on the production process. Ultrasonic sewing can withstand about 5kg. But the sewing and cross-stitching reinforcement can maximize the load-bearing performance of the fabric. Therefore, different thicknesses can be selected according to different industries, uses, and costs. If it is used as the inner packaging of clothing, shoes and bags, a non-woven fabric with a thickness of 60g is sufficient. And if it is used for the outer packaging of small commodities and advertising non-woven bags, a non-woven fabric with a thickness of 70g is sufficient. However, due to quality and aesthetic considerations, this cost is generally not saved.
If the non-woven bag is used for packaging food or larger products, and the weight of the product exceeds 5kg, it is recommended that the non-woven fabric is more than 80g, and the production process needs to be machine-sewn.
Therefore, in general, the thickness of the non-woven fabric can be selected according to its use and the load-bearing requirements of the product. When choosing the thickness of the non-woven fabric, you can select it appropriately according to the above reference data.
